The TDLS Open Path Solution
NEO Monitors new HF Open Path Gas monitor specifically designed for service in hazardous areas. Based on our third generation LaserGas Technology, the entire instrument is build into compact flameproof enclosures making it fit for zone 1 and division 1 applications. The LaserGasTMIII HF OP consists of a transmitter and receiver unit that are mounted opposite each other at distances up to 100 meters. The laser light is sent from the transmitter to the receiver and any HF concentration changes along the optical path from the transmitter and receiver are detected in real-time.
