GDYQ-101S/201S Indoor Air Field Formaldehyde Concentration Tester

GDYQ-101S/201S on-site formaldehyde analyzer is a new portable on-site formaldehyde quantification instrument, widely used in furniture, flooring, wallpaper, coatings, horticulture, interior decoration and renovation, dyes, papermaking, pharmaceuticals, medical, anti-corrosion, disinfection, fertilizers, resins, adhesives and pesticides, raw materials, samples, process and production workshops and living places for on-site quantitative determination of formaldehyde.
Instrument features:
1. National standard method - Phenol reagent colorimetric method (GB/T18204.26-2000)
2. Detection speed 12 minutes
3. Specialized sample pretreatment equipment and disposable reagent kits
4. Directly display the sampling amount
5. Quantitatively measure the formaldehyde content in the air on site
Instrument principle:
The principle of the portable on-site formaldehyde analyzer is based on the colorimetric analysis method established by the selective absorption of visible light by blue-green compounds generated by the reaction of formaldehyde in the tested sample with a color reagent. 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 on the LCD screen.
Instrument features:
·Using national standard methods (GB/T18204, 26-2000), formaldehyde concentration can be directly displayed;
·Can measure formaldehyde in gas and liquid samples on site;
·Chemical reagent packaging for color development, with minimal sample and reagent usage, prevents and reduces secondary pollution;
·Pulse mode power supply, low power consumption, one 9V battery can be used for more than 40 hours. After stopping the input command for 10 minutes, it will automatically power off;
