IR-BA Series High-speed Compact Radiation Thermometers

The IR-BA series is a non-contact and high-speed compact radiation thermometer. The card sized thermometer with built-in signal converting function of 4-20mA output can easily be installed in narrow places, production lines and small equipment.
A standard speed type and a high-speed type (50ms/95%) are respectively available in standard type and small-target/short-distance type and small-target/long-distance type, and special application types for glass, lamp-anneal, film, and burning gas..
