Portable Formaldehyde Meter

The handheld formaldehyde concentration meter uses an electrochemical sensor. During detection, formaldehyde molecules undergo redox reactions at the electrodes, generating current signals, which are then converted into concentration readings through the circuit. It is used for on-site rapid detection of formaldehyde levels in indoor air and furniture materials, typically covering a detection range of 0-10 ppm, with a response time of about 30 seconds.
Selection
When selecting, prioritize sensor lifespan and anti-interference capability, with dedicated formaldehyde sensors being superior to composite types. The measurement range should cover the common standard of 0.1–2 mg/m³. It should include temperature and humidity compensation functionality. Check for calibration certificates from metrology institutions. Compare the reading stability of different brands under identical environmental conditions. Prefer models equipped with dust filtration at the air intake.
