technical data:power supply voltage 230v 50hz power consumption 3w.operating temperature from -10 °c to +40 °c.relative air humidity from 30% to 95%.sensor type - semiconductor japanese production durability 10 years.threshold concentration value - approximately 15% of the lower explosive limit.alarm signaling - optical and acoustic (red diode 85db piezo acoustic membrane).dimensions 120x80x45 mm.weight 0.30 kg. cable length 1.5mthis product is a response to the high market demand for devices that control gas installations ventilation systems and central heating furnaces installed in our apartments houses and public buildings. The device is particularly sought after by customers during the autumn and winter months. Our product is entirely manufactured in poland. It is laboratory tested using special gas mixtures to ensure the device will operate correctly when a concentration of gas hazardous to humans is present.the maxi/k-gp detector is designed to monitor closed rooms for the presence of flammable gases: methane and propane-butane. The detector continuously measures the gas concentration in the surrounding air. When the gas concentration exceeds approximately 15% of the lower explosive limit (i.e. at a gas concentration approximately 7 times lower than that at which the gas can explode) an optical and acoustic alarm is activated. The maxi/k-gp230 model has additional outputs enabling connection to alarm systems and control of solenoid valves and acoustic-light modules (siren lamp). The alarm is automatically deactivated when the gas concentration drops below the alarm threshold.the maxi/k-gp detector is designed to monitor closed rooms for the presence of flammable gases: methane and propane-butane.the detector continuously measures the gas concentration in the surrounding air.when the gas concentration exceeds approximately 15% of the lower explosive limit (i.e. at a gas concentration approximately 7 times lower than that at which gas can explode)the optical and acoustic alarm signal is activated.additional outputs enable connection to alarm systems and control of solenoid valves and acoustic-light modules (siren lamp). the alarm is automatically switched off when the gas concentration drops below the alarm threshold.applications of the maxi gas detector:domestic boiler rooms with natural gas or propane-butane furnacesbathrooms kitchens equipped with gas appliances e.g. Cookers stoves water heatersrooms with gas appliances i.e. Gas meters cylinders tanks gas pipes (basements corridors) portable gas heatershome car garages with lpg gas installationsschool physics and chemistry laboratoriescamping trailers and yachts**illustrative photo.
