Temperature Calibrators AMETEK PTC Series
The PTC series portable temperature calibrator combines laboratory features such as a wide temperature range, high accuracy, stability and speed with Ametek’s well-known and long-standing quality and reliability, in a single industrial calibrator. Three temperature calibrator models (A;B;C) are available for each type, from a basic unit to a complete model including signal inputs and external reference sensor.
The PTC series calibrator features dual-zone active temperature control, which provides excellent temperature homogeneity in the thermal block and insert.
Automatic calibration function (auto-step) in 20 temperature points, controlled locally or remotely by PC through the JofraCal application.
Through the JofraCal Ametek PC software application, Calibration Certificates can be automatically issued and databases can be created with records of all tested sensors.
