Additional Features
OMEGA’s new hot point® calibrators allow calibration of thermocouple and RTD probes quickly and easily with 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 CL900 calibrator accepts a variety of standard and metric optional inserts which are available in 4" and 6" depths and for probe diameters from 1/8" to 3/8". An undrilled insert is also available. The CL900 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.
The CL950 calibrator features a built-in well with 5 ports sized to accommodate a 1/16", 1/8", 3/16", and two 1/4" diameter probes. The multi-port design allows for the use of a calibrated or NIST-traceable probe and meter to be used as a standard while calibrating other probes. The 5 port design also allows for calibration of more than one probe at a time, and eliminates the need for separate insert wells.

I have type J thermocouples with brazed junction, can I calibrate with a dry well calibrator
Thank you for your inquiry. As long as the thermocouple is the proper diameter and meet the minimum depth/length requirement, it can be used in this well.
