The Wahl TC622A is a pocket size RTD calibrator, designed to simplify the maintenance and commissioning of of temperature transmitters and probes. This model can measure or generate 12 different types of RTD temperatures and resistance at an accuracy of 0.02%.
With IP54 protection, these portable units are suitable for onsite use, even in demanding environmental conditions. The graphical interface makes reading easier, and allows for viewing of graphical or test formats. Memory can hold 10,000 values. Advanced functionalities include square root, steps, synthesizer, and statistical functions. Powered by four alkaline AA sized batteries.
Values can be displayed in °C, °F, mV, and Ω. Unit features a low temperature coefficient: 7 ppm /°C for resistance.
The TC622A comes with two sets of test leads. Two sets of 12436-16 Test Leads are required to perform 3 or 4 wire measurements.
This meter has a LEMO 4 pin connector. Our TMA series handheld RTD probes fit this meter.
