Two-color pyrometer CellaTemp® PA 50

digital°C°F

Product description:
The CellaTemp® PA 50 is a digital two-colour pyrometer for contactless temperature measurement in the range 500–1,400 °C. The two-colour measuring method reduces sensitivity to disturbances from dust, dirty protective windows or changing surface emissivity. For precise aiming the instrument can be equipped with through-the-lens sighting, a laser pilot light or a camera module.

• Measuring range 500 to 1,400 °C
• Focusable interchangeable lenses for exact adjustment of measuring distance
• Broadband anti-reflective precision optics
• 4-digit red LED display, digit height 8 mm, readable at distance
