Three Test Methods for Indoor Formaldehyde Pollution Level

The formaldehyde self-test kit is the cheapest and most domestic formaldehyde detection method with large numerical deviations.

The formaldehyde self-test box is generally composed of a brown bottle of diluent, a transparent bottle of color developer, and a reaction box filled with powder.

Although this method is simple, the accuracy cannot be guaranteed, and only a rough test can be done.

Home formaldehyde detector

The household formaldehyde detector uses electrochemical sensors and high-precision operational amplifier chips to directly and continuously convert the formaldehyde concentration signal in the air into electrical signals in real time.

Compared with the detection cost of several thousand yuan by a formaldehyde testing agency, a household formaldehyde meter of several hundred yuan can fully meet the needs of ordinary families, and the operation is very simple, and the compact size is also easy to place.

Formaldehyde testing agency

The method of hiring a formaldehyde testing agency to do indoor environmental testing is obviously more suitable for large organizations such as enterprises and units.

Testing agencies need to pass the measurement certification (CMA) of the quality and technical supervision department above the provincial level before they can issue a legally effective report.

　　It should also be noted that some institutions without testing qualifications will deceive consumers with "free testing", and the feasibility of their data is worthy of scrutiny, while some testing institutions that do both testing and governance are advised to choose carefully, because national regulations require testing agencies Do not engage in related businesses that affect the test results.
