Calex Electronics
Calex Electronics is a UK-based manufacturer specializing in non-contact infrared temperature measurement solutions for industrial applications. Calex products deliver accurate, reliable, and fast temperature readings without physical contact, making them ideal for harsh or demanding environments.
The product range includes infrared temperature sensors (pyrometers), temperature indicators, controllers, data loggers, and blackbody calibration sources — providing complete solutions for temperature monitoring and process control.
Calex infrared devices measure temperatures of moving, inaccessible, or extremely hot surfaces such as metals, glass, plastics, paper, asphalt, and food products. Engineered for industrial reliability, Calex solutions offer wide temperature ranges, high accuracy, fast response times, and easy integration with PLC and control systems via standard industrial outputs.
