thermoMETER CTM-4: High speed & compact infrared pyrometer for low temperatures


The infrared pyrometer from Micro-Epsilon enables precise and non-contact temperature measurements in the range from 0 °C to 500 °C. The thermoMETER CTM-4 surpasses the previously known measurement speeds on the market. Compared to previous measurement values in the millisecond range, a signal of just 90 µs is sufficient for temperature detection using the CTM-4. The temperature value is output every 300 µs.

The spectral range of 2.2 to 6 µm wavelength opens up a wide range of applications. It enables the measurement of metals and non-metals such as ceramics or plastics. The measuring system is particularly well suited to fast measurements of hot melt glue in the packaging industry. Furthermore, fast-moving components such as wheel bearings and brakes of railway wagons can be measured whilst the train is moving.

Controller and sensor are installed separately which is a space-saving method to enable integration even in restricted spaces. Measurement values can be output via different interfaces. For quick parameter set up, the integrated USB interface is used. The CompactPlus Connect software is included in the scope of supply and offers various setting options.


  • High measurement speed for extremely fast processes
  • Measurement of metals and non-metals due to large, short-wave spectral range
  • Temperature measurement from 0 °C, ideal for industrial applications
  • Integrated USB interface
