OMEGA’s hot point™ calibrator is part of a new family of calibrators which allows calibration of thermistor, thermocouple and RTD probes quickly and easily with an accuracy to ±0.8°C (±1.5°F). An integral RTD sensor assures high measurement accuracy and repeatability. A built-in microprocessor-based PID digital controller assures exceptional stability. Setpoint and actual temperature are displayed, simultaneously. Temperature can be set in one degree increments from Ambient +22 to 482°C (Ambient +40 to 900°F).


The CL900A calibrator accepts a variety of optional inserts which are available in 4" and 6" depths, and probe diameters from 1/8" to 3/8". An undrilled insert is also available. The CL900A comes standard with a 1/4" diameter, 6" deep insert well, and insert removal tongs. Additional inserts can be ordered separately as required for other diameter probes. 6" depth inserts are used for probes 7" and longer. 4" depth inserts are used for probes 5" and longer..
