  • Quick and Accurate Way to Check the Calibration of IR Pyrometers
  • Fixed Temperature from 35°C to 150°C - Depending on Model
  • Outstanding Temperature Stability, Less than ±0.2°C Deviation
  • LED Temperature Indication



The FTK provides a quick and accurate way to check the calibration of infrared temperature sensors. These rugged and portable units are designed to provide fast calibration checks anywhere they are needed, from the factory to the workshop or laboratory. Eighteen models are available; offering target temperatures from 35°C or 150°C, all providing outstanding stability with less than ±0.2°C deviation.

The FTK takes between 5 and 15 minutes to heat and stabilize at the desired temperature (depending on the model), and uses a clear LED to show when it has reached that temperature: Green when the FTK is warming up, Orange when the FTK is ready for operation and Red when the FTK is above the calibration temperature.

The FTK can be used with any infrared temperature sensor that is able to measure between 35°C and 150°C and can focus on a target area less than 50.8 mm diameter.
