Pump-priming DSA2000-NO2 nitrogen dioxide detector

Pump-priming DSA2000-NO2 nitrogen dioxide detector using imported high-precision electrochemical characteristic principle of the sensor matrix liquid crystal display technology, you can display the kind of gas, the gas unit, gas concentration, measured maximum, local time, temperature and other support English operation interface, easy to switch gas concentration unit PPM, mg / m3 can quickly switch the display built-in mini pump, pump suction size adjustable features ten stalls or confined space monitoring of environmental concentrations of nitrogen dioxide and alarm with self-checking function, zero calibration function, so that gas monitoring is more accurate, more reliable and restore the factory settings function, can be removed from misuse problems with temperature and pressure compensation, it can achieve the perfect environment at different temperatures and pressures of the gas concentration Compensation levels sound and light alarm, alarm point can be set to high-capacity lithium polymer rechargeable battery pump suction sampler means of their own, the pump suction size adjustable housing made of high strength special plastic, non-slip, waterproof, dustproof, explosion exquisite high-end The aluminum suitcase application furniture, flooring, wallpaper, paint, gardening, interior decoration and renovation, dyes, paper, pharmaceutical, medical, food, antiseptic and disinfectant, fertilizers, resins, adhesives and pesticides, raw materials, sample, process and breeding plants, waste treatment plants, perm place in biopharmaceutical production plant, home environment, livestock breeding, greenhouse cultivation, logistics, wine fermentation, agricultural production? specifications Gas Detected measured gas nitrogen dioxide (NO2) detection principle Detection principle electrochemical principle sampling Sampling Method pump-priming, flow rates up to 1L / min, pump suction size ten stalls adjustable range Measure Range 0-10ppm, 0-20ppm, 0-50ppm, 0-100ppm, 0 -500ppm, 0-1000ppm, 0-2000ppm, 0-5000ppm (range options, are not listed range can be customized) Resolution Resolution 0.001ppm (0-10ppm), 0.01ppm (0-20ppm, 0-50ppm, 0 -100ppm), 0.1ppm (0-500ppm), 1ppm (0-1000ppm above) and 2% FS accuracy Precision Response Time Response Time ≤10S Recovery Time Recovery Time ≤10S Repeatability Repeatability ≤ ± 1% linearity error Linearity error ≤ ± 1% Zero drift Zero shift ≤ ± 1% (FS / years) display technology Display LCD dot matrix display technology Manipulation Language Operating language support in English gas unit Gas unit supports multiple gas unit switching display Operating temperature Temperature -40 ℃ ~ 70 ℃ Humidity Humidity 0-95% RH Explosion Proof Explosion-Proof ExiaⅡCT4 protection Degree of protection IP66 Alarm Alarm mode sound, light, vibration hours Operating time 100 hours (off pump) Dimensions Dimensions 205 * 75 * 32mm Weight 300g weight
