Product Description
Working Principle
Put sample into 1 square meter test chamber, under specify temperature, humidity, air velocity. The formaldehyde will released from samples and mixed with the air in the chamber, the air will be drawn through the absorption bottle is filled with distilled water, all the formaldehyde in air dissolve in the water; Measure the amount of formaldehyde in the absorption solution and extraction of air volume, and show it by micrograms per cubic meter (mg/m³).
