NEWPORT’s hot point® calibrator is part of a new family of calibrators which allows calibration of thermocouple and RTD probes quickly and easily with an accuracy to 0.9°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 22°C (40°F) above ambient to 482°C (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 complete with a 1/4" diameter, 6" deep insert well, and insert block 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.
