The PIECAL 422 is a rugged, easy to use Automated Thermocouple Calibrator you can use to check & calibrate all your thermocouple instruments and measure thermocouple sensors.

The PIECAL 422 gives you the ability to:
  • Carry it without worry - it comes protected with a rubber boot and rugged, low profile switch.
  • Easy viewing - Large backlight display
  • Work will all process instruments - Works with older instruments and newer multi-channel instruments that switch between input channels.
  • Measure thermocouple sensors - Troubleshoot sensor connections and find broken wires or corroded connections.

PIECAL Calibrators Competitive Edge

PIECAL Calibrators are designed and built by members of the same team that designed and built the calibrators manufactured by Fluke under the Altek label.

PIECAL 422 vs. Altek 422
In comparison the PIECAL 422 improves upon other popular calibrator brands, such as the Altek 422, by including a larger display with backlight, making it easier to use, more resistant to accidental damage and more!
