Product Details
The principle of GDYQ-203S formaldehyde analyzer is based on the colorimetric analysis method established by the selective absorption of visible light by colored compounds generated by the reaction of formaldehyde and color reagents in the tested sample. The instrument consists of a silicon light source, a colorimetric bottle, an integrated photoelectric sensor, and a microprocessor, which can directly display the formaldehyde content in the tested sample.

Instrument features:
1. Adopting the national standard method (GB/T18204.26-2000). 2. Suitable for quantitative determination of formaldehyde concentration in indoor or outdoor gas samples. 3. Controlled by a microcontroller, it has spectral data processing function. 4. The chemical reagent package for color development requires minimal sample and reagent usage, preventing and reducing secondary pollution. 5. Small size, light weight, and easy to carry. |
