Single Input Intrinsically Safe Thermocouple Thermometer

K, J, T, E , N, R, S & B Thermocouple Probes

The Model 921B is a single-channel intrinsically safe digital thermometer compatible with type K, J, T,E , N, R, S  or B thermocouple probes to provide a wide range of temperature measurements, (-418 °F to 2502 °F) certified intrinsically safe for use in potentially hazardous environments. The 921B boasts a 2000 hour battery life using three AA batteries.  The 921B provides dependable and uninterrupted portable measurement capability without expensive batteries, AC adapters or chargers.

The creative ergonomic design makes these I.S. thermocouple thermometers easy to hold, easy to read and easy to clean.  Designed for one-handed operation, these tools are comfortable to carry and use for extended periods of time.  The heavy-duty case is specifically designed for durability and resistance to contaminants such as dust and chemicals. The smooth, sleek, seamless case means that cleaning is quick and certain.

Real-time statistical data increases user productivity, process efficiency and product quality. Displayed on-demand MIN, MAX, AVG, RNG and STDEV (standard deviation) provide critical process information and diagnostics that allow the user to analyze manufacturing processes on the fly and make immediate adjustments for maximum efficiency and quality.

Like all TEGAM products, our intrinsically safe thermocouple thermometers are designed, assembled and tested in the United States but are ATEX-compliant for European applications.  TEGAM backs this durable instrument with a standard 3 year warranty and a 2 year calibration guarantee to insure that your instrument is ready to use when you need it.

TEGAM intrinsically safe products are ideal for measuring temperature in potentially hazardous environments such as those found within the aerospace, automotive, pharmaceutical, oil & gas, chemical, textiles, and mining industries and even some food processing applications.
