Details

The IN 140/5 is a digital pyrometer for non-contact temperature measurement of glass and quartz glass surfaces with temperature ranges between 250 and 2500 °C.

The instrument is characterized by a very short response time and extremely small spot sizes. Thus it is applicable for fast measuring tasks and for the measurement of smallest objects.

The type IN 140/5-L is equipped with a optics with better field of view (optics 2-NL).

The high speed version IN 140/5-H has a shorter response time of only 10 ms.

For optimal match of the instrument to the application (size of the measuring object, measuring distance) different focusable optics are available. The exact alignment of the measuring object will be achieved by a laser targeting light or a optimized thru-lens view finder.

The pyrometer is equipped with a display which shows in measuring mode the current temperature. Additionally all parameters can be read if they are changed via the integrated keys at the instrument.

Via serial interface and the provided software InfraWin the temperature can be displayed and stored on a PC, parameterizing can also be done. The diagnostics function allows to check pyrometer and wiring.

Typical Applications

  • Flat glass fabrication
  • Bulb production
  • Car glass assembly
  • Glass bending
