The CL515-PLUS works with the RTDs you use including Platinum 100 (alpha = 3850, 3902, 3926) & 1000 (alpha = 3850, 3750) Ω, Copper 10 & 50 Ω, Nickel 100 and 120 Ω. 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. Select the step time to match your system from 5, 6, 7, 8, 10, 15, 20, 25, 30 and 60 seconds.

Carry it without worry, it comes protected with a rubber boot and rugged, low profile switch. Easy to operate even in dark areas with the backlit display.
