The REED R2310-NIST is a rugged handheld infrared thermometer built for quick, non-contact surface readings from -35C to 650C (-31F to 1202F) at a 12:1 distance-to-spot ratio. Its IP65-rated, double-molded housing shrugs off dust and drop impacts, while a built-in laser sighting aid, adjustable emissivity, and backlit display make it easy to target and read in the field. Onboard min/max/average/differential tracking plus user-set high/low alarms suit routine maintenance and inspection work, and this unit ships with a NIST-traceable calibration certificate for applications that require documented accuracy.
