Neomonitors LaserGas™ III OP HF Gas Detector is specifically designed for service in hazardous areas. Based on our third generation LaserGas™ Technology. Built into compact flameproof enclosures making it fit for zone 1 applications. The LaserGas™ III OP HF consists of a transmitter and receiver unit that is mounted diametrically opposite each other at distances up to 100 meters. The laser light is sent from the transmitter to the receiver. HF concentration changes along the optical path from the transmitter to the receiver are detected in real-time.
