LaserGas™ III OP


check Fast response time
check Automatic health check
check Suitable for harsh environment

LaserGas™ III Open Path gas detector is specifically designed for continuous monitoring in hazardous areas.
Based on our third generation LaserGas™ Technology, the entire instrument is built into compact flameproof enclosures which makes it ideal for zone 1 locations.
The LaserGas™ III OP consists of a transmitter and receiver unit that is mounted facing each other at distances up to 100 meters. The laser light is sent from the transmitter to the receiver and any changes in gas concentration along the optical path from the transmitter to the receiver are detected in real-time.
