Description

With the CL542-PLUS you can check and calibrate all your thermocouple instruments and measure thermocouple sensors.

Calibrate Directly in Temperature (°C and °F)
Stop carrying around a millivolt source and thermocouple tables. The CL542-PLUS works with the thermocouples you use including Types J, T, E, K, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and Platinel II. Easily set any value quickly to within 0.1° with the adjustable digital potentiometer “DIAL” plus store any three temperatures for instant recall with the check switch.

Calibrate Quickly with Automatic Output Stepping
Choose between 2, 3, 5, 11 and 21 steps to automatically increment the output in 100%, 50%, 25%, 10% or 5% of span.

Compatible with All Process Instruments
Connect directly to the thermocouple inputs of smart transmitters, PLCs, DCS and multichannel recorders and verify their outputs or displays. Carry it without worry—it comes protected with a rubber boot and rugged, low profile switch. Easy to operate even in the dark areas of the plant with the backlit display.
