Gas detector STANDGAS

O2COmethane

STANDGAS HC is a stand-alone detector using catalytic technology for the detection of butane-propane, methane-natural gas and hydrogen provided with a relay output. It is available a special versión with three programmable relays. Stand-alone functioning: not connected to a control panel. Allows for the automatic selection of the gas to detect, from any of the available gases, through use of an established protocol using a jumper. – Detection range from 0 to 100% L.E.L. – Optical indicator for sensor fault & status. – 1 alarm relay output programmable with two options (20% L.E.L and 50% L.E.L), instantaneous/delayed disconnection, programmable disconnection delay and initial relay status when at rest. Up to three levels in the special version or two levels plus fault output. – Voltage supply from 10V to 30V DC. STANDGAS PRO is a stand-alone detector using electrochemical and infrared technology for the detection of toxic gases and O2 provided with three programmable alarm relay outputs with different levels for each gas. Available gases: CO, NO2, NH3, H2S, Cl2, SO2, CO2, O2, SF6 and refrigerant gases. – Digital control of sensor status. – Hardware automatic testing. – Digital filter based on variable samplings of the averages in sensor values. – Automatic thermal compensation that supplies a correct response when faced with temperature variations (STANDGAS O2 does not need this characteristic).
