As of 2021 Martel Calibrators are no longer being manufactured. Support is limited as service and replacement parts become harder to find. This includes several models which were labeled under other brand names.
A Martel Calibrator is large with lots of buttons versus the small size and easy to use interface of a PIE Calibrator. The Martel MC-1010 and Martel MC-1210 process calibrators require complicated hookups with easily lost jumper wires for RTD connections while the PIE 820 & PIE 830 use true 2, 3 & 4 wire connections. The Martel PTC-8010 Thermocouple/RTD calibrator require miniature thermocouple connectors to plug in wires while the PIE 525B accept bare thermocouple wires under screws as well as miniature thermocouple connectors.
Find hidden problems in 4 to 20 milliamp loops, broken wires from RTD sensors and excessive loop loads with troubleshooting features found only on PIE calibrators. Upgrade your Martel calibrator with a PIE Evolutionary Calibrator and see how much easier it is to use and how much time you save on each calibration.
