Applications: Production Lines, Food, Metal, Glass, Ceramics, Rubber, Synthetic Resin, Medical, Petrochemical, Automotive, Electrical, Industrial


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.

The On-Line Infrared Thermometers, Models 15201-15204, are engineered specifically for use on the production line to measure moving objects quickly and accurately from a safe distance. These infrared thermometers measure targets within a temperature range of 32°F to 932°F (0°C to 500°C) with a 500 millisecond response, at a ±1% level of precision.
