  • Temperature ranges between 550 and 3300 °C
  • Video output
  • Spot size marker for exact alignment

Details

The pyrometers IS 140-TV and IGA 140-TV are digital, highly accurate pyrometers for non-contact temperature measurement on metals, ceramics, graphite etc. They are equipped with a color camera module which enables the optical alignment of the pyrometer to the measuring object via video screen or monitor.

The monitor shows the actual measuring temperature as well as the adjusted emissivity of the pyrometer. Additionally the date and the time and a free selectable text can be displayed.
