HD-P800 handheld home formaldehyde formaldehyde detector tester

I. Product Overview HD-P800 is a professional formaldehyde detection instruments, it can be called a portable / handheld formaldehyde detection equipment, when the instrument detects air formaldehyde gas concentration reaches the set alarm value, there will be alarm, prevent poisoning incidents occur. The core of the instrument as a gas sensor, is the use of sensors to detect the type of gas in the air, is used to detect the composition and content of formaldehyde, so we should pay attention to when purchasing this regard, do not blindly buy. Second, the instrument is classified formaldehyde detection equipment introduced into the sampling mode Diffusion and pump-priming two, HD-P800 is the use of detection equipment formaldehyde diffusion Sampling Method: Diffusion-type gas detector gas detection region of the free flow of air Slow sample gas flow into the instrument for detection; pump gas detector is the instrument equipped with a small air pump, which works by power driven pump to treat gas sampling survey area was evacuated, and then the sample gas will be fed into the meter testing. Pump gas detector is characterized by fast detection of dangerous areas can now be remotely measure, the company's HD-P900 gas detector is the use of pump-priming sampling mode. Specific selection based on customer needs to be. Third, the product features * formaldehyde detection equipment using imported high-precision sensor; * dot matrix liquid crystal display technology, support Chinese and English display interface; * gas concentration unit PPM, mg / m3, etc. can quickly switch the display * ultra buzzer alarm sounds, two alarm level values ??can set your own; * with a data storage function, you can view the historical data on the instrument may also be connected to the computer to export the print data (optional); * high-capacity lithium polymer rechargeable battery, you can ensure that the instrument for a long time in a row work; * Rugged upscale alligator clip for easy carrying during operation; * Housing made of high strength special plastic, durable, attractive appearance, feel good; * exquisite high-end aluminum instrument package Fourth, the technical parameters measured gas formaldehyde gas detection principle more than thirty kinds of sensors can be selected freely combined, flexible configuration (based on customer needs can simultaneously support four kinds of gas detection) Sampling Method Diffusion (optional external pump) Range Range can select a test based on specific customer gas given resolution 0.001ppm, 0.1ppm (range associated with the selected resolution) accuracy 3% FS Alarm sound and light alarm, alarm status three options: on, off, mute data recorded over 10 million units of stored data , 4 sensor, five minutes storage interval can be stored for 15 months in a row, storage interval 10-3600 seconds adjustable (optional) Battery 3.7V rechargeable lithium battery, the battery capacity 1800mA signal output USB interface high speed data transmission, coupled with position the software can download and print data (optional) Response time ≤10S recovery time ≤10S charging time of less than 6h monochrome dot matrix display technology 128 * 128 LCD graphic display operating language support for English gas unit supports multiple gas unit to switch the display operating temperature -20 ℃ ~ 50 ℃ Operating Humidity 0-95% RH Protection IP66 Explosion levels ExiaⅡCT4 housing material ABS + PC working longer than 50h size 155 * 78 * 35mm Weight 300g HD-P800 gas detector can detect not only formaldehyde gas, can also be detect any toxic or flammable gases can be detected at the same time, two, three, four gases, whether gas sensor or circuit chips, each one is the use of foreign imported chips for explosion-proof circuit design, safe to use.
