Pump-suction formaldehyde Tester

The pump-suction formaldehyde detector actively draws air samples through a built-in micro air pump, allowing the air to flow through an electrochemical sensor. The electrolyte within the sensor undergoes a redox reaction with formaldehyde, generating an electric current signal. This signal is amplified and processed by the circuit, and the formaldehyde concentration is directly displayed on the screen. This instrument is used for rapid on-site detection of formaldehyde emissions in indoor air, furniture panels, and textiles.
Selection
When selecting, focus on sensor lifespan and anti-interference capability to avoid readings being affected by substances like alcohol. Check for the pattern approval mark and verification certificate of the measuring instrument. Compare whether the sampling flow range covers 10-30 liters per minute. Ensure the instrument’s response time reaches a stable value within 2 minutes. Consider data storage functions and pump noise levels, and choose a device within the 0-10 ppm range based on your budget.
