feature:
*Professional formaldehyde detection multi-function sensor
*The use of air convection in electrochemical sensors solves the problem that traditional sensors cannot effectively cope with gas interference. It uses step-by-step filtration to accurately capture formaldehyde molecules to ensure the accuracy and stability of detection.
*Semiconductor sensor measurement covers a variety of gases, including methanol, toluene, and xylene ammonia detection, more comprehensively detecting gas amounts to protect the health of your family
