Metis model MY45 and MY46 pyrometers are used for boiler and furnace applications that measure CO2 gas and flame temperature. These IR temperature sensors measure temperature in the high absorption CO2 gas band wavelength. At this optimized wavelength, the PSC model MY45/46 sensors measure Hot CO2 gas, which is a constituent of an oxygenated flame. Standard MY46 temperature measurement ranges of 932 (500°C) to 3632°F (2000°C). Starting temperature ranges for the MY45 are 212 (100°C) to 2732°F (1500°C). Other temperature ranges available upon request.
