Palmer Wahl T150 | High Precision Temperature Field Calibrator | TC, RTD and thermistor
The Palmer Wahl T150 is a dual-channel field calibrator dedicated to temperature, covering thermocouples, RTDs (platinum, nickel and copper) and thermistors. Its two channels can be set as IN/IN for comparison and differential measurement, or IN/OUT to simulate temperature into recorders, indicators and handheld thermometers. Best accuracies are quoted at 0.005% of reading for thermocouples and 0.006% for RTDs and thermistors, and it can drive dry blocks, furnaces and baths with a 4-20 mA signal.
