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.
