Infrared pyrometers from Optris use non-contact sensing to determine the surface temperature of an object based on its emitted infrared radiation. They can read the temperature of inaccessible or moving objects without difficulty. CS LT series infrared pyrometers are suited for temperature measurement in small and narrow environments. They feature stainless-steel construction, broad measuring range of -50 °C to 1,030 °C (-58 °F to 1,886°F), and a rating for use in ambient temperatures up to 80 °C (176 °F) without needing added cooling. CSmicro miniature infrared pyrometers can be used in ambient temperatures up to 120 °C (248°F), while their small size allows installation in tight spaces. They’re also CE marked, RoHS compliant and have two-year warranty.
