1. This product is small in size, light in weight, easy to carry, accurate in reading, and able to feel the surrounding air anytime, anywhere.
2. Portable formaldehyde HCHO, TVOC gas concentration detector, 3 color lights (green / yellow / red) alarm for indoor home security.
3. Using the global mainstream chemical sensor, using 12-bit AD smart chip, ultra-sensitivity detection of formaldehyde, multi-layer microporous filtration, effectively eliminating interference such as ethanol, oxidation, formaldehyde measurement accuracy increased by 50%.
4. Two models, B01 detection principle is the principle of electrochemical gas sensor, B03 detection principle is the principle of semiconductor gas sensor, energy saving and environmental protection, B01 electrochemical precision is higher.5. Wide range of uses: can be used for outdoor travel testing, home decoration testing, industrial gas testing, office testing.
