GAOTek Handheld Air Sampling Pump for NO2 Detection

Description Overview GAOTek Handheld Air Sampling Pump for NO2 Detection is based on advanced infrared and electrochemical technology for measuring 100% LEL, 1000 ppm CO, 30% O2, and 100 ppm H2S concentration, with optional H2, CO, and gas flow items. Compact, rugged, and robust, the portable multi-gas detector is well-suited for many applications where the presence of multiple gases needs to be monitored (e.g., underground coal, digesters, methane recovery, waste and water treatment).   Features Detects 4 gases with a resolution of 0.5% vol/1ppm High & low alarm function: sounds, lights, and vibrates Digital LCD display: Displays real-time gas concentration value with backlight Durable power supply: rechargeable battery that can last for more than 12 hours Data logger & transfer in real time   Technical Specifications Usage Industrial Processing/Personal Safety Gases detected H2S/CO/O2/CH4/CO2/LEL/SO2/NO2/NO Sensor types Infrared/Electrochemical/(Customized) Sensor life ≥5 years (NDIR/Infrared)≥2 years (Electrochemical) ≥1 years (Catalytic combustion) Triple alarm Sound/Light/Vibration Battery Short Circuit Current 2A Working current 95 mA Continuous operating hours ≥ 12 hours Air Sample Method Diffusion Battery Pl123450 3.7 V / 1500 mAh Charging time 4 hours to 5 hours Certificate CE/Ex Id I Working temperature -10°F to 131°F (-25°C to 55°C);short time for -40°F to 131°F (-40°C to 55°C) Certificate CE/Exi bd I Size 5.12 in x2.6 in x 1.18 in (130 mm x 66 mm x30 mm) Weight 40 lb (250 g)
