Xi'an Indoor Air Testing Center recommends that where newly renovated houses are best tested in Xi'an Formaldehyde.

The formaldehyde content of formaldehyde in the indoor air environment can be divided into:

(1) AHMT Spectrophotometry

(2) Phenol reagent spectrophotometry

(3) Gas chromatography

(4) Acetylacetone Spectrophotometry

(5) Electrochemical sensor method

Detection of electronic sensing equipment (including 4160 PPM400 BGFM-06, etc.) The accuracy of the formaldehyde self-testing agents on the market should be carefully selected.

(6) Formaldehyde self-test box detection method

Formaldehyde self-test box is a kind of semi-quantitative detection product that can quickly, simply, and cost-effectively detect indoor formaldehyde concentration or treatment effect.
