On-site calibrations

Ametek says it has designed the new JOFRA ATC (Advanced Temperature Calibrator) dry-block industrial calibrator to be a complete portable test laboratory which the user can program and then use on the process line to calibrate at temperatures up to 650 degrees C.

With a completely new core element, the three models in the series are designed to meet the new EA guidelines, established by European standard laboratories. The instruments are also novel in being constructed for calibrating many different types of sensor, including liquid-filled and large mechanical types.

Unusual for a dry-block heater, the heating element is constructed with two independently controlled zones. An upper active part offers homogeneity close to that of a laboratory liquid bath while the lower region ensures optimal heat dissipation throughout the entire block. And there is no need to insulate the sensor under test.
