Product description:The CellaPort PT 140 is a digital two-colour pyrometer for temperature measurement from 500 to 3,000 °C. The two-colour measuring principle reduces sensitivity to interference from dust, vapour, dirty protective windows and changing target surfaces compared with single-colour pyrometers. A through-the-lens sighting enables easy and precise aiming of the measuring spot.
