Temperature monitoring instruments at DAS Company cover the complete range of industrial, commercial and regulatory temperature measurement applications beyond the simple PID temperature controller category — panel-mount digital temperature indicators for HVAC plant rooms and process panels; USB data loggers for HACCP cold chain verification, transport monitoring and laboratory environmental recording; wireless and WiFi temperature loggers for continuous building, warehouse and cold room monitoring with remote access; 21 CFR Part 11 validated monitoring systems for pharmaceutical, biotech and medical device cold storage requiring regulated electronic records; and multi-channel chart recorders and wired sensor networks for industrial process monitoring with PT100, PT1000 and thermocouple inputs.
The correct temperature monitor specification depends on the regulatory framework that applies to the monitored process. EN 12830 (Temperature recorders for the transport, storage and distribution of temperature-sensitive goods) is the European standard for cold chain monitoring equipment in food logistics, pharmaceutical distribution and clinical sample handling. 21 CFR Part 11 (FDA) and EU GMP Annex 11 (European Medicines Agency) cover pharmaceutical manufacturing and storage requiring validated electronic records, electronic signature workflows and audit trails. HACCP (Hazard Analysis Critical Control Points) under EU Regulation 852/2004 applies to all food business operators handling temperature-sensitive products. DAS Company supplies CE-marked temperature monitoring equipment with documented compliance to the applicable standards for the customer's industry — supporting auditable record-keeping for regulated operations across Europe.
Panel-mount digital temperature indicators provide direct visual display of process temperature on industrial control panels and HVAC plant room cabinets — accepting PT100 RTD, PT1000 RTD and thermocouple (Type J, K, T, S, R) sensor inputs and displaying the measured temperature on a 3, 4 or 5-digit LED or LCD display in standard DIN panel cutout sizes (48×48mm, 72×72mm and 96×96mm). Unlike PID temperature controllers (which actively control heating outputs based on temperature feedback), temperature indicators are display-only devices — providing operator visibility of temperature without the control output function or PID tuning complexity. Indicators are the appropriate specification for monitoring points where temperature is displayed for operator awareness but actively controlled by a separate device, or where the temperature value is read by operators for manual process decisions.
Common configuration features include multiple display channels (single-temperature display, dual-temperature display with min/max recording, scrolling multi-channel display for up to 8 measurement points), high and low alarm relay outputs (energising warning lights, sirens or BMS digital inputs when measured temperature exceeds preset limits), 4–20 mA or 0–10 V analogue retransmission (sending the measured temperature to a remote BMS or SCADA system), and Modbus RTU communication (RS-485 communication for integration with PLC and BMS systems). DAS Company supplies panel-mount temperature indicators from Enda (ET and ETC series), Selec, Autonics and other panel instrument manufacturers in our authorised brand portfolio.
USB temperature data loggers are compact, battery-powered devices that continuously record temperature at configurable intervals (typically 30 seconds to 60 minutes) for the duration of a monitored process — from food cold chain transport (typically 3–7 day journey monitoring) through pharmaceutical distribution (shipment-duration monitoring with single-use disposable loggers) to laboratory environmental recording (continuous multi-month monitoring of incubators, refrigerators and storage cabinets). The recorded temperature data is downloaded by direct USB connection to a PC at the end of the monitoring period, generating compliance-ready PDF and CSV reports with min/max statistics, alarm event records and the complete temperature trend graph required for HACCP and regulatory submission.
Standard USB logger features include integrated internal sensor (built into the logger body, suitable for ambient air temperature measurement) or external probe connection (separate probe on cable, allowing the logger to be mounted outside the monitored space while the probe is inside refrigerator, freezer or oven), configurable measurement range and interval (typically -40°C to +85°C for standard cold chain; -200°C to +250°C with external probe variants for industrial process monitoring), tamper-evident operation (visible LED indication of alarm events and tamper-resistant button protection), and EN 12830 certification for cold chain temperature recording equipment. The PDF report generated directly from the logger memory (no separate software installation required on the destination PC) provides regulatory-compliant documentation that food safety inspectors, pharmaceutical QA personnel and customs officials accept without additional verification. Single-use disposable loggers (typically 3–6 month battery life, used once and disposed of) provide cost-effective per-shipment monitoring; reusable loggers with replaceable battery provide multi-year service life for fixed installation in warehouses and cold storage facilities.
WiFi and wireless temperature loggers provide continuous remote temperature monitoring without the cable infrastructure of wired sensor networks — the appropriate specification for retrofit cold room monitoring, warehouse environmental monitoring, museum and archive climate control verification, and laboratory cold storage where running new sensor cables is impractical or excessively costly. Battery-powered WiFi loggers transmit temperature readings at configurable intervals (typically every 5–15 minutes) to a cloud platform via the building WiFi network — providing real-time temperature visibility on smartphone and browser dashboards from any internet-connected location, with automated alarm notification (email, SMS) when temperature exceeds preset limits.
Cloud-based monitoring platforms (typically subscription-based, supplied with the logger or hardware) aggregate data from multiple loggers across one or many sites into a unified dashboard — supporting multi-site cold storage networks (food distribution centres, pharmaceutical wholesalers, retail chain back-of-store cold rooms) and geographically distributed facility monitoring (multi-building hospital pharmacy, multi-site biobank, distributed agricultural cold storage). Standard features include 2-channel sensor input (temperature plus optional humidity, door open/closed status, or second external probe), alarm escalation rules (text alarm at first threshold, phone call at extended threshold, automated logging of alarm response actions), and compliance report generation (automated weekly and monthly reports with temperature statistics, alarm event lists and graphical trend output for HACCP, GMP and quality management system documentation).
Pharmaceutical manufacturing, biotech research, clinical trials and medical device storage applications subject to FDA 21 CFR Part 11 (US) and EU GMP Annex 11 (Europe) regulatory frameworks require temperature monitoring systems with documented validated controls that paper temperature charts and standard USB loggers cannot provide. The regulatory framework requires electronic records that are demonstrably unaltered from the point of measurement to the point of regulatory submission, electronic signatures that uniquely identify the individual performing record review and approval, audit trails recording every system access and data manipulation event, and validated software that has been formally tested against documented user requirements specifications and performance criteria.
DAS Company supplies pharmaceutical-grade temperature monitoring systems with the regulatory compliance documentation required for GMP-validated installation — including IQ (Installation Qualification) documentation confirming the system has been installed according to specification, OQ (Operational Qualification) documentation confirming the system performs to documented requirements, supplier quality system documentation (ISO 9001 and where applicable ISO 13485) and 21 CFR Part 11 compliance statements from the system manufacturer. Validated cold storage monitoring is typical in vaccine storage and distribution (clinic and hospital pharmacy vaccine fridge monitoring), biobank and clinical trial sample storage (-80°C ultra-low temperature freezer monitoring), pharmaceutical bulk and finished product cold storage warehouses, and pharmaceutical stability testing chambers.
Temperature monitoring systems use one of three primary sensor technologies depending on the temperature range and accuracy requirements of the application. PT100 RTD (Resistance Temperature Detector) sensors — platinum resistance elements with characteristic resistance of 100 Ω at 0°C — provide the highest accuracy (typical ±0.15°C Class A, ±0.3°C Class B per EN 60751) across the -50°C to +400°C range. PT100 is the standard sensor specification for pharmaceutical, food and laboratory applications requiring high-accuracy temperature measurement. PT1000 RTD sensors (1000 Ω at 0°C) provide equivalent accuracy with reduced cable resistance sensitivity — appropriate for long-cable installations where PT100 lead resistance would introduce measurement error. Thermocouple sensors (Type K nickel-chromium for -200°C to +1372°C, Type J iron-constantan for -210°C to +1200°C, Type T copper-constantan for cryogenic applications, Type S platinum for high-temperature furnace and kiln applications) provide a wider temperature range than RTD sensors but lower accuracy (typical ±1.5°C to ±2.5°C class) — appropriate for industrial process temperature measurement, oven and furnace monitoring where RTD limits are exceeded.
DAS Company supplies complete temperature sensor solutions for installed monitoring systems — PT100 and PT1000 immersion probes (stainless steel sheath, threaded compression fittings, M12 connector or terminal head versions), thermocouple probes (mineral-insulated stainless construction, ceramic high-temperature sheaths, surface-mount magnetic probes), RTD transmitters (4–20 mA output transmitters for PT100/PT1000 sensors providing long-distance transmission and noise immunity), and sensor cable (compensating cable for thermocouples, screened cable for low-level RTD signals). Calibration certificate options provide UKAS, DAkkS or equivalent national-laboratory traceability for sensor calibration in regulated industries.
Multi-channel paperless chart recorders provide on-screen temperature trend display and electronic data archive for industrial process monitoring applications — typically 4, 8, 12 or 16 universal input channels (PT100, thermocouple, mA, V configurable per channel), 5–7" colour TFT display with on-screen trend graphs, SD card or USB data export, Modbus TCP/RTU communication and integrated alarm relay outputs. Paperless recorders have largely replaced traditional ink-and-paper chart recorders in industrial process applications — providing better data resolution, easier data archival and remote access through Modbus and Ethernet integration with SCADA and PLC systems. Process applications include pasteurisation hold tank monitoring, oven and autoclave validation cycle recording, sterilisation cycle Bowie-Dick and load probe recording for medical device manufacturing, and continuous process temperature documentation for ISO 9001 and IATF 16949 regulated manufacturing.
