Course overview

Temperature instrument calibration must verify correct output from the primary element. It also verifies proper operation of the remaining sensor circuitry.

The Temperature Calibrators training course investigates the most common equipment needed to perform temperature instrument calibration. It explains the equipment's basic function and operation.

Temperature Calibrators is part of the Test Equipment training series.
