Affiliate Jincheng instrument supply H-2000 type PM2.5 detector portable formaldehyde detector

Jincheng instrument joined H-2000-type air purifiers efficiency portable formaldehyde detector detector cities PM2.5 particles are burst table every day! ! That our family is not exceeded super? In the end how much particulate matter? Air purifiers really can remove particulate matter PM2.5 it? Now you only need a PM2.5 particle detector. Real-time control at home parent can each place pm2.5 particles in the end how much! ! Instrument Description: CLH-2000-type air purifiers efficiency detector is designed to measure the volume of air cleaner dust particles out of the air within the air units and calculate the efficiency of the instrument according to the number of dust particles out of the air intake which is advanced haltech companies. High sensitivity based on micro-sensor technology to develop a set of independent aerodynamics, digital signal processing, optical and electrical integration of high-tech products. The basic principle is the laser scattering by dust particles on the pulse signal output by the optical sensor digital signal processing, measurement parameters setting, the results showed that key, the time, date, etc. by the built-in microcomputer (MCU) and to achieve control. CLH-2000-type air purifiers efficiency detector can simultaneously both size range (0.3,2.5) were detected and analyzed, the instrument is set to default before the measurement, the instrument is, then the user will get a unit volume measured at the inlet The number of particles in the dust automatically after 20 seconds after the display settings, the user at this time took the instrument to measure the outlet for 20 seconds after the measurement is automatically calculated based on the number of dust particles out of the air outlet which currently measured purifying machine purification efficiency. The test instrument has high precision, stable performance, versatility and strong, easy to operate, meet and exceed all performance of similar products. Its purification efficiency air purifier targeted testing, effectively reflects its purification effect. Users only need to use this instrument were air purifier inlet and outlet were measured, it can accurately reflect the number of real-time particulate matter before its purification, and calculate the percentage of its purification efficiency, therefore, this instrument is very useful for air purification purifier effectiveness analysis testing. Air purifiers detector efficiency is mainly imported from abroad with high sensitivity, high resolution, high stability and high precision sensor dust particle analysis is an important part of the pump through the pump to collect data, and then through the sensor detection and analysis and then analyze the data in real time to reflect on the LCD monitor.

Formaldehyde pollution on human health hazards of formaldehyde has been identified by WHO as carcinogenic and teratogenic substances, is a recognized source of allergy is caused by one of the strong potential mutagens. Studies have shown that: Formaldehyde has a strong carcinogenic and tumor promotion. Well documented, the impact on human health formaldehyde mainly in abnormal smell, irritation, allergy, pulmonary function abnormalities, liver dysfunction and immune dysfunction and so on. Its concentration reaches 0.06 -0.07 mg per cubic meter of air / hour m3, minor child asthma occurs. When the indoor air formaldehyde content of 0.1 mg / m3 when there is smell and discomfort; reached 0.5 mg / m3, can irritate the eyes, causing tears; reach 0.6 mg / m3, can cause throat discomfort or pain. At higher concentrations, can cause nausea, vomiting, cough, chest tightness, shortness of breath or pulmonary edema; reach 30 mg / when m3, would immediately cause death. Long-term exposure to low doses of formaldehyde can cause chronic respiratory disease, caused by nasopharyngeal cancer, colon cancer, brain tumor, menstrual disorders, mutations nucleus, within the DNA single-strand DNA cross-linking and cross-linking of proteins and inhibit the repair of DNA damage, pregnancy syndrome, cause neonatal chromosomal abnormalities, leukemia, causing adolescent memory and mental decline. In all contact persons, children and pregnant women are particularly sensitive to formaldehyde more harmful. World Health Organization (WHO) working group had formaldehyde provides its smell, eye irritation and respiratory tract irritation potential carcinogenicity threshold, and noted that when the concentration of formaldehyde in the indoor environment exceeded 10%, it should be taken seriously enough. Formaldehyde serious pollution hazard sites newly renovated rooms, offices, conference rooms, hotels, KTV rooms and home. With malls, shopping malls and other building materials. Formaldehyde and other indoor air pollution in people's new home and office interior spaces should be carried out and buy homes. Club, due to renovations and home. To use a lot of artificial board manufacturing (such as plywood, Daixinban, MDF, particleboard, Laminate flooring and laminate flooring, etc.), production of wood-based panels and require extensive use of highly toxic raw materials for the manufacture of formaldehyde adhesives, due to the release of formaldehyde adhesives for a long period, usually 15 years, resulting in formaldehyde in indoor air has become a major pollutants. In mid-August 2001, the Consumers Association released a startling findings, respectively, after the sampling of indoor air show in Beijing and Hangzhou, the formaldehyde concentration in excess of 73.3%, respectively, and 79.1%, exceeding the highest reach forty times. Last year, the inspection department of the Beijing area have nine home. With the city conducted air quality testing, sampling and found that formaldehyde is higher than the average of the test results public places 3.3 times the standard. Public health standards higher than the maximum 15.8 times, exceeding 98% of the sample, respectively. July 2001 Hefei health department informed the office and indoor air monitoring results for the city's 15 monitoring points: formaldehyde exceeded all, up to 85 times. Indoor air pollution alarming. Hefei ICBC branch co-workers installed yellow for 15 months, but the two offices has pervaded "smell" and often found a large number of dead worms, workers have also repeatedly reflected tears, sore throat, chest tightness, headache other symptoms. Monitoring results showed that the office exceeded 45 times a formaldehyde, an overweight 29-fold. According to Nanjing Indoor Environment Monitoring Center staff surnamed Qian introduction, the center was established in response to public request two months, a total of 30 sets of Nanjing residents near the newly renovated rooms were monitored, almost no one can fully meet the "China Health Standard indoor environmental standards ", the main problem is formaldehyde, formaldehyde as high as 40 times. Sichuan Provincial Institute of Industrial Hygiene and Occupational Disease Prevention informed that the recently renovated for over 1500 of the room and the office, the office for testing found that indoor air pollution greatly exceed national health standards. More than 95% of the room within formaldehyde exceed health standards, up more than 60 times the standard; some organs Office Interior excessive levels of formaldehyde in the air several times to several times.
