This sampling pump is an accessory specifically developed this gas detector, It helps the gas detector detect gas concentraion of narrow or complicated environments,air flow velocity is about 0.5 cubic inches per hour,maximun gas sample collecting distance is about 50 feet, providing higher sensitivity for the detector effectively. 2. It does not operate independently,it needs to work with the voltage from the gas detector.Therefore,the sampling pump must be connected to the detector with 2 screws,please do not connect any other voltage power supply to the sampling pump to avoid burn out the pump. 3. When you are using the sampling pump,please ensure tighten up the sampling pump to the gas detector with 2 closed type screws,avoiding poor contact. DETAILED SPECIFICATIONS Color: Black Operating voltage range: DC 2.2V-3.2V Working current:<280mA Nozzle diameter: 2.5mm Minimum operating voltage:2.2V Noice :<75 dB Size:100.8*62.3*50mm Standard packing:sampling pump/user manual/soft rubber tube(500mm long).
