Saf Eye Quasar 950 Open Path Gas Detector 01440

The latest SafEye Quasar open path UV detection technology, the Quasar 950, detects toxic Hydrogen Sulfide gas with path lengths of up to 200ft (60m). The Quasar 950 can be tailored to protect your personnel and high-risk installation. Reliability is key and is assured with SIL2.

All Quasar 950 detectors incorporate heated windows to minimize any effects from condensation, icing, snow and are totally immune to interference from sunlight or any other sources of radiation such as flare stacks, arc welding or lightning. A range of outputs are available including mA, HART, Modbus RS485 to suit all control systems.
