Air Pollution Detection Sampling Method--Formaldehyde Detector

The indoor formaldehyde detector is the latest spectrophotometer developed. It is an on-site detection instrument that can detect six indoor pollutants (formaldehyde, benzene, ammonia, toluene, xylene, TVOC) at the same time. It has a full touch button design, a large LCD screen to display temperature and humidity environmental conditions, integrated chip control, and the gas detection time can be adjusted by electronic control. After reaching the set time, it can automatically stop working. The formaldehyde LCD display reading can be read on site to obtain accurate formaldehyde results. The built-in micro printer can directly print temperature, humidity, formaldehyde concentration, detection unit, detection date and time, and excessive results. At the same time, the external sampler is stored in the box, which is more portable and light. It is easy to operate, reasonably designed, and beautiful in appearance. This instrument has passed the measurement and testing certification of the National Environmental Protection and Health Research Association, reached the national standard, and issued a test qualification report. The scope of application of this instrument: It is suitable for supervision, monitoring agencies, governance companies, decoration and decoration companies, construction companies, workshops and mines, and can also be used for scientific research, teaching, and laboratories.

    The "Indoor Environmental Quality Evaluation Standard" clearly stipulates the sampling requirements for monitoring and evaluation. The number of sampling points is determined according to the size of the indoor area and the on-site conditions. Generally, 1 to 3 points are set for rooms below 50 square meters, 3 to 5 points are set for rooms between 50 and 100 square meters, and at least 5 points are set for rooms above 100 square meters, with diagonal or plum blossom-shaped points. When sampling, ventilation ducts and vents should be avoided, and the distance from the wall should be greater than 1 meter. The sampling point is 0.8 to 1.5 meters above the ground. When evaluating a room, sampling should be carried out under normal activity conditions, and monitoring should be carried out for at least one day, twice a day, without opening doors and windows; when evaluating an office building, sampling should be carried out when no one is active, and monitoring should be carried out for at least one day, twice a day, without opening doors and windows.

Indoor air pollution detection tips
　　For indoor air quality detection, consumers know that they need to find qualified testing agencies, but they don’t know about some important details that directly affect the test results during the most important test process, or even know nothing about them. In fact, any test has strict test conditions, especially when consumers want to use the test results as evidence to resolve disputes or even conduct legal proceedings. The test report without the test conditions is just a piece of waste paper. Therefore, the following introduces some test conditions stipulated in national standards, so that you can better communicate and cooperate with the testing units in future air quality tests, and supervise the standardized operation of the testing agencies to obtain more objective and reliable test conclusions.
