Enhanced versions of noncontact ST Series infrared thermometers provide greater accuracy and range, says the manufacturer. Circular laser sighting better frames the measurement area on the targeted object, and improved optical resolution measures smaller areas from the same distance (or the same area from a greater distance), the company says. These features can result in quicker, higher-confidence measurements that increase the productivity of hvacr technicians, the manufacturer claims.
