| What equipment is useful for testing before removing formaldehyde? | |
| 2021-06-01 | |
| Removal of formaldehyde after renovation is a problem faced by many friends. There are also many formaldehyde detection tools on the market, such as in addition to home detectors. What is the effect? Let's first see if the home detector is effective. The detection accuracy of gaseous pollutants such as formaldehyde with the built-in electrochemical sensor of the household self-checker is easily affected by other gas impurities. Household formaldehyde detectors, as a convenient method of formaldehyde detection, are still very popular in the market, but portable formaldehyde detectors do not have a suction pump. The concentration of formaldehyde refers to the amount of formaldehyde in a certain volume. If there is no gas pump to suck the gas, the gas volume cannot be accurately measured, and the result of calculating the concentration is naturally inaccurate. There is no regular calibration. As the formaldehyde detector is used, there will be errors, even if it is not used for a long time, there will be inaccuracies, so regular calibration is necessary. In addition, the detection technology adopted by the household convenient formaldehyde detector is not as accurate as the professional formaldehyde detector due to the limitation of hardware. The limitations of the above-mentioned various conditions have caused the inspection results of the household convenient formaldehyde detector, which is not an error, but has no reference meaning at all. The atmospheric sampler plays a very good role in the detection of harmful gases in the air and the environment. With the continuous advancement of science and technology, air samplers are constantly introducing new products, such as: intelligent air samplers, explosion-proof air samplers, dual gas path air samplers, etc., which have greatly enriched the classification of air samplers. The air sampler is equipped with a suction pump, divided into single channel; and dual channel; or even three channels or more. It is widely used in indoor air detection, atmospheric environment monitoring, sanitation and epidemic prevention, labor protection, industrial hygiene and other fields. Therefore, the use of professional instruments for precise sampling and hue analyzer analysis to confirm pollution sources for different materials can reduce data errors. |
