Monochromatic pyrometer CellaCombustion PA 18

with LED display°C°F

Product description
The CellaCombustion PA 18 is an infrared pyrometer designed to measure the temperature of hot combustion gases in combustion chambers of incineration processes, power plants and waste-to-energy facilities. Using a focusable precision lens and either through-the-lens sighting or an optional video camera, the instrument can be aligned precisely with the measuring spot.

Special features

• Measuring range 500 to 2,500 °C
• Focusable lenses for exact adjustment of the measuring distance
• Broadband anti-reflective precision lens
• LED display readable at long distance (4 x 7-segment, digit height 8 mm)
• Test current output for diagnostic checks
• Standard interfaces: digital I/O, two analogue outputs, USB and RS-485
