The RTD and Thermocouple Calibrator is an ideal device to handle all of your temperature calibration needs in a truly rugged, low-cost package.  It combines virtually all widely used thermocouples and RTDs in one device - you'll never have to worry about finding a temperature device you can't calibrate.  This is especially true when calibrating "smart" or pulsed RTD transmitters, where many other RTD calibrators fail to work or operate at reduced accuracy specs.

Comes complete with calibrator, set of 4 AA Alkaline batteries, (2) test lead sets, protective rubber boot, printed instruction manual, and NIST calibration certificate.
