High Accuracy RTD Auto-Connect Display Calibrator & Thermometer

With the CL515-PLUS you can check and calibrate all your RTD instruments and measure RTD Sensors. Automatic indication of connections on the display for simple hookups.

Stop carrying around a decade box and RTD resistance tables. The CL515-PLUS works with the RTDs you use including Platinum 100 (alpha = 3850, 3902, 3926) & 1000 (alpha = 3850, 3750) Ohm, Copper 10 & 50 Ohm, Nickel 100 and 120 Ohm. 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 the dark areas of the plant with the backlit display.
