Everest Interscience Inc. has introduced its Series 4000.4GX ultrahigh-speed infrared temperature transducers. The temperature response time is 20 ms with a turn-on time of 10 ms. The sensors are housed in a stainless steel case, and their connectors are also stainless steel, making the instruments stable in varying environments. They provide precision measurements from 240 °F to 2200 °F and do not require artificial cooling below 160 °F. A ball-and-socket swivel mount is included.
