Product Description

• Easy to use

With the OMEGA CL540A Series you can check & calibrate all your thermocouple instruments.

• Take it without into the shop, plant or field

Carry it without worry - protect it with an optional rubber boot and rugged, low profile switches.
Easy to operate even in the dark areas of the plant with the backlit display.

• Calibrate directly in temperature (°C & °F)

Stop carrying around a millivolt source and thermocouple tables. The OMEGA CL540A Series
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 DIAL switch.

• 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.
