HD-P900 portable formaldehyde detector formaldehyde detector

I. Introduction HD-P900 for the pump-priming formaldehyde detector, using imported sensors to detect toxic formaldehyde customers more choices electrochemical type and semiconductor type sensor: Electrochemical type: gas occurs on the electrode electrochemical reflecting the output signal measured gas concentration sensor. Semiconductor-type: by measuring the electrical properties of semiconductors change before and after exposure to the gas detection of gas concentrations. Relatively low cost, fast response. The product from one place to another, carrying alarm formaldehyde can be used. Second, the technical parameters of the measured gas formaldehyde detection principle electrochemical principle, the principle of infrared semiconductor principle, PID photoionization principle sampling pump-priming, flow rates up to 1L / min, pump suction size ten stalls adjustable range 0 -10ppm, 20ppm, 50ppm, 100ppm range options) Resolution depending on the specific sensor accuracy and range may be fixed, as the sensor signal output USB interface to high-speed data transmission, you can download and print data (optional) Response time ≤10S recovery time ≤ 10S repeatability ≤ ± 1% linearity error ≤ ± 1% Zero drift ≤ ± 1% (FS / Year) dot matrix liquid crystal display technology, display technology Manipulation Language Support English gas unit supports multiple gas unit switching display Operating temperature -40 ℃ ~ 70 ℃ Operating Humidity 0-95% RH Protection IP66 Explosion levels ExiaⅡCT4 Alarm sound, light, vibration work 100 hours (off pump) Dimensions 205 * 75 * 32mm Weight 300g Third, the application areas u petrochemicals, industrial production, refining forging, electricity, coal, engineering, environmental monitoring, sewage treatment u biopharmaceutical, home environment, livestock breeding, greenhouse cultivation, logistics, wine fermentation, agricultural production u fire, gas, building construction, municipal enterprises, school laboratory, Research center u furniture, flooring, wallpaper, paint, gardening, interior decoration and renovation, dyes, paper, pharmaceutical, medical, food, preservative Fourth, quality, price, sale and formaldehyde detector and the company's other gas detectors are After Shandong University art reproduction study must undergo a secondary inspection before shipment, if there are questions, prohibit the sale, because we are the real manufacturer, so customers are all sold to the wholesale price, without any intermediate distributors nature, product life-long maintenance, a dedicated product support guide, you can take me home products and other home products to compare a look at our product quality, price, sale and, if you have any questions or needs any time online customer service Consulting or call 18853178077 or 0531-58675676 QQ: 1349192507 to let us know.
