FAQs
for Thermocouple Thermometers
The supported thermocouple types depend on the model. The 911B and 912B digital thermometers support K, J, T, and E. The 921B/922B intrinsically safe models and 931B/932B data logging models extend compatibility to additional high-temperature types including B, N, R, and S, giving broader coverage for demanding applications.
The 900 Series is specified at ±0.04% of reading + 0.3 °C, making it suitable for quality-critical measurement tasks. The instruments also include a probe offset function, allowing users to compensate for known probe-related error and improve overall system accuracy.
The 921B and 922B are the intrinsically safe models in the range. They are intended for use in hazardous locations where flammable gases, vapours, or dust may be present, making them appropriate for applications such as petrochemical facilities, fueling areas, and similar environments.
The 931B and 932B include internal memory for up to 1000 readings and Bluetooth Low Energy connectivity. This allows users to record measurements directly on the device and transfer or stream data to a compatible mobile device or PC for analysis, record keeping, and reporting.
Dual-channel models such as the 912B, 922B, and 932B can monitor two temperature points at the same time. They also provide a temperature difference display, which is especially useful for comparative diagnostics, inlet/outlet checks, and process efficiency evaluations.
The probe offset function allows users to enter a known correction value for a thermocouple probe. This helps compensate for minor sensor deviation and aligns displayed readings more closely with a verified reference, which is valuable when tighter measurement control is required.
These instruments are designed for demanding industrial and laboratory use. The ergonomic sealed housing supports one-handed operation and is built to withstand routine exposure to dust, chemicals, shocks, and general field handling, helping maintain reliability in harsh working conditions.
All models are powered by three standard AA batteries. The standard digital and intrinsically safe versions provide around 2000 hours of operation, while the Bluetooth data logging versions provide around 1000 hours, supporting long service intervals between battery changes.
The recommended calibration interval for the 900 Series is 2 years under normal use. This extended cycle helps reduce maintenance downtime while supporting confidence in long-term measurement performance. Optional accredited calibration services may also be available when documented traceability is required.
