ML SERIES is a rugged and compact IR Pyrometer especially designed for low temperature application needs, ranging from 0°C...1000°C.The highly recommended and OEM favourite model is perfectly suitable for demanding industrial environment because of the compact size, and low maintenance.

ML SERIES is particularly a tough competitor due to its high performance at very attractive economy range. AST ML SERIES model can replace the already installed contact probes with the K type or J type thermocouple output along with standard 2 wire 4...20mA, 0..5V/0..10V analog outputs, J & K type thermocouple, Sensing head usable up to 180°C ambient Temperature. AST ML SERIES IR pyrometer comes along with digital TTL Output and Alarm Output for variety of applications in process industries.
