TSP #241 - Ametek Jofra CTC-140A (-17C TO +140C) Dry Block Calibrator Repair & Teardown
In this episode Shahriar takes a look at a faulty dry block calibrator from Ametek. These Jofra series temperature calibrators are widely used for thermostat validation as well as material analysis. This particular unit does not cool down or warm up but seems otherwise functional.
A brief set of measurements shows that one of the Peltier elements is damaged and should be replaced. A replacement is located and the temperature well is re-sealed. The unit is functional and the minimum temperature performance is verified.
