A built-in coaxial laser marker easily targets objects, with a 30mm diameter field of view. It has a 1°resolution on its digital display, and a 0.2°output resolution. Temperature scale is °F/°C switchable.
　　One of its most unique features is the E-TEACH function for automatic adjustment of the emissivity ratio. The On-Line Infrared Thermometers have two choices of analog output: TV-type (1mV/°C) which connects to such devices as a panel meter, or TA-type (4-20mA), for long distance transmissions. An optional air purge collar adapts this unit to dusty environments.
　　Applications range from the manufacturing of food, metal, glass, ceramics, rubber, synthetic resin, to medical, petrochemical, automotive, electrical and industrial uses.
