HS-130AS Sensor for detecting ethanol, also detects isobutane and hydrogen
HS-131 Sensor, mainly for detecting methane gas (CH)4). The sensor also reacts extremely sensitively to liquid gasses isobutane and propane
HS-133 Sensor, mainly for detecting liquid gasses isobutane and propane. Also suitable for detecting natural gas because of its high sensitivity to methane
HS-134 Sensor for detecting carbon monoxide, also conditionally suitable for detecting hydrogen
HS-135 Sensor for detecting air pollution, sensitive to isobutane (i-C4H10), alcohols, sulphur dioxide (SO2)and carbon dioxide (CO)2)
Note: After long periods of storage and shutdowns, the sensors should be connected to the power supply for at least 24 hours before they can provide reliable data
