This calibrator sources and reads 11 thermocouple types (A, B, C, D, E, J, K, N, R, S, T) and 5 RTD types (Pt100, Pt200, Pt500, Pt1000, Cu50), plus DC voltage and resistance, making it a versatile bench tool for checking meters, controllers, transmitters, data loggers, and recorders. A 6-digit LCD with backlight, zero-adjust button, and internal cold-junction compensation support accurate readings, while a built-in LED flashlight, low-battery indicator, and auto shut-off round out the field-friendly design. It runs on 3 AA batteries and comes with test leads, a thermocouple adapter, and alligator clips.
