The TEGAM 922B Dual-Input Intrinsically Safe Thermocouple Thermometer (922B / 78909-33) is designed for portable temperature measurement in potentially hazardous environments where flammable liquids, gases, vapours or combustible materials may be present. It accepts eight thermocouple types and can monitor two temperatures simultaneously or display one channel together with the difference between channels.
Key Features
- Certified intrinsically safe design, intended for temperature measurement in potentially hazardous locations
- ATEX-compliant for European applications, with UL and CE intrinsic-safety certification listed by TEGAM
- Dual thermocouple inputs, allowing two temperature points to be monitored simultaneously
- Supports J, K, T, E, N, R, S and B thermocouples, covering a broad range of industrial temperature applications
- Measurement range extends from -250 to 1820°C depending on thermocouple type, providing coverage from cryogenic to high-temperature applications
- Accuracy of ±(0.04% of reading + 0.3°C), supporting dependable process and maintenance measurements
- T1-T2 differential measurement, enabling direct comparison between two process points
- Probe offset function, allowing known probe errors to be compensated to improve overall measurement uncertainty
- Real-time statistical functions, displaying minimum, maximum, average, range and standard deviation on demand
- Backlit auto-resolution display, providing 0.1° resolution below 1000° and 1° resolution at higher values
- Approximately 2000 hours of battery life, providing extended portable use from three standard AA batteries
- Seamless ergonomic enclosure, designed for one-handed operation and easier cleaning in demanding environments
Benefits
- Measure temperature in approved hazardous-location applications using an intrinsically safe handheld instrument.
- Monitor two process points simultaneously and view the temperature difference directly as T1-T2.
- Use one thermometer with eight thermocouple types across a wide range of industrial processes.
- Reduce battery-change interruptions with approximately 2000 hours of operation from standard AA batteries.
- Assess process stability directly in the field using built-in minimum, maximum, average, range and standard-deviation statistics.
