Indoor environmental testing equipment portable ammonia detector

I. Overview HD-P900 portable pump suction ammonia detector, with built-in micro-pump, pump suction size and there are dozens of stalls adjustable, can quickly detect ammonia gas concentration in the air environment. HD-P900 ammonia detector using imported electrochemical sensors, there are very clear large LCD screen, dot matrix liquid crystal display technology, even in harsh environments can also be used to detect gas concentration of ammonia in the air, once they reach set When the alarm sound, light, vibration alarm occurs. Continuous detection of up to 100 hours, and it can be used continuously for about four days. Second, the technical parameters of the measured gas ammonia detection principle electrochemical principle, the principle of infrared semiconductor principle, PID photoionization principle and other sampling methods pump-priming, flow rates up to 1L / min, pump suction size ten stalls adjustable Range 0-50ppm, 0-100ppm, 0-200ppm (range options) resolution 0.01ppm, 0.1ppm accuracy of 2% FS (more precisely optional) signal output USB interface to high-speed data transmission, you can download and print the 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 a plurality of 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 product features Introduction HD-P900 portable ammonia detector, whether the sensor or circuit chip, are using imported first-class brand, because the sensor is at the heart of the instrument, the quality of the sensor directly affects the quality of products as well as life, on this basis, technical personnel also built miniature pump, the pump suction size ten stalls adjustable blocking the pump does not appear, as proof circuit design, while with the circuit protection design, with high accuracy, good stability, repeat and good features, the overall machine living in the domestic advanced level. Fourth, the instrument features A HD-P900 portable ammonia detector uses the original imported sensor, quality assurance; B The instrument display dot matrix liquid crystal display technology, clearly and accurately display the gas type and gas unit; C when in use operational mistakes, you can restore the factory settings; D gas concentration unit can be automatically switched; E pump suction size of ten stalls adjustable,; F explosion-proof certification, explosion-proof grade ExiaⅡCT4, ease of use; G Shell waterproof, explosion-proof, anti-skid, dust and other; H packaging is exquisite high-end aluminum suitcase; I use this instrument problems during the warranty period, if repairs can not be solved through commissioning, the factory is responsible for issuing new goods if you have any needs You can always contact customer service online or call to let us know.
