LaserGas III SP

LaserGas III Single Path analyser for oxygen is designed for service in hazardous areas. Based on our third generation LaserGas electronics, the entire instrument is built into compact flameproof enclosures, making it operative in zone 1 and class l division 1 areas.

The LaserGas III SP is our most reliable gas sensor with all electronics designed according to IEC 61508 and SIL 2 (safety integrity level). Based on the fully digital Gen. 3 compact LaserGas electronics, the analyser has a response time of 100 msec.

The LaserGas III SP O2 consists of a transmitter and receiver unit (mounted diametrically opposite each other) to measure the average gas concentration along the optical line-of-sight. Path lengths are typically from 0.5 to 20 meters.
