Temperature Calibrator

Product Overview

APSL-C211 and APSL-C251 Temperature Calibrators are high-precision, high-resolution and highly reliable handheld calibrators integrating measurement and simulation of RTDs and thermocouples, as well as output and measurement of electrical parameters such as voltage, millivolt and resistance. Equipped with a high-brightness backlit large display screen, it features simple operation, robust structure, compact lightweight design and cost-effectiveness. Suitable for instrument workshops, metrology rooms and calibration laboratories, it is an ideal calibration instrument for process control instruments.
