A combustible gas is any gas that will burn. Mixtures of combustible gases with air, when ignited, produce an explosion. Use a combustible gas sensor to insure that the percentage of gas in the air can never get high enough for the mixture to burn. When gas is sensed, try to replace the gas/air mixture with fresh air. If this, then shut down all equipment and evacuate all personnel from the area. Use these sensors to check for methane (natural gas), propane, butane, ethane, pentane, LNG, LPG, hydrogen and other combustible gases.

GC801 Combustible Gas NOVA-Sensor® uses the traditional “catalytic” method of gas detection. The NOVA-Sensor continuously displays the gas concentration in large, easy to read characters. A standard 4-20 milliamp circuit transmits the gas reading to other control equipment. Three sets of voltage free contacts provided for control or shutdown of equipment. Available in standard, weatherproof, and dust-proof models.

GC800 Combustible Gas Sensor. Save money by installing this model in locations where the gas concentration display and relay contacts are not required. Uses the same catalytic sensor as our NOVA-Sensor for reliable and accurate measurements. A standard 4-20 milliamp circuit transmits the gas reading to other control equipment. Available in standard, weatherproof, and dust-proof models.

GIR901 Infrared Combustible Gas NOVA-Sensor® uses the newer IR technology to sense gas. IR sensors are very stable and do not require recalibration on a regular basis. The NOVA-Sensor continuously displays the gas concentration in large, easy to read characters. A standard 4-20 milliamp circuit transmits the gas reading to other control equipment. Three sets of voltage free contacts provided for control or shutdown of equipment. Available in standard, weatherproof, and dust-proof models.
