Instrument features:

1. The instrument is the latest revised version of GB16129 "Hygienic Inspection Standard for Formaldehyde in the Atmosphere of Residential Areas" - phenol reagent on-site colorimetric method.

2. The detection instrument consists of detection, sampling, and heating modules, achieving integrated sampling and detection for convenient on-site use.

3. The instrument has a built-in working curve and does not require the preparation of standard solutions. After sampling, adding matching reagents for color development can achieve rapid on-site quantitative determination of formaldehyde.

4. The instrument is equipped with a built-in lithium battery, which can work continuously for more than 8 hours. The instrument is small in size, light in weight, easy to carry, and can achieve on-site testing.

5. The instrument is equipped with a dedicated 19mm colorimetric bottle, which can be used as both a reaction bottle and a measurement bottle. Greatly convenient for customers to use and reduces human error.

6. Using disposable specialized reagent kits, with minimal reagent usage and easy operation.
