TRAT Series

The TRAT series can be used in various heat treatment processes, and also be fitted with special block for IN-SITU calibration.

This block allows the insertion of another thermocouple for calibration by comparison without the need to remove the same process.

The CQI-9 requirement was established by the Automotive Industry Action Group (AIAG) in order to develop a management system thermal process to enable defect prevention and the reduction of variation and losses in the supply chain.
The reason that led the companies to carry out the heat treatment process with care CQI-9 requirement is that it was common for heat treated parts were the causes of problems in passenger vehicles, trucks and buses.

The system consists mainly of the following tests:

System Accuracy Test (SAT) - is the comparison of temperature values generated by a thermocouple control against temperature values generated by a thermocouple accuracy test.

Temperature uniformity rating (TUS) - is to monitor the temperature variation within the furnace working zone relative to the setpoint temperature.
