Pyrometer IMPAC Series 140 View

Key Features

  • Measurement of plastic films, especially extremely thin PE and PP films with a thickness from 30 µm
  • Temperature range 50 to 500 °C
  • Spectral range 3.43 µm

Details

The IPE 140/34 is a special pyrometer for non-contact temperature measurement of plastic films, especially extremely thin Polyethylen- or Polypropylen films with a minimum material thickness of only 30 µm.

Like the basic IPE 140, the IPE 140/34 is a highly accurate digital pyrometer. It is operating in an extremely narrow spectral range of 3.43 µm. This enables the precise measurement of plastic films.

3 different focusable optics are available for optimal match of the instrument to the application.
