Air Formaldehyde Content Detector

The air formaldehyde detector uses an electrochemical sensor that comes into contact with the air. Formaldehyde molecules undergo redox reactions at the electrodes, generating current signals, which are then converted by the circuit into concentration readings. It is used for monitoring formaldehyde concentrations in enclosed spaces such as indoor environments and vehicles to ensure environmental safety.
Selection
When selecting, focus on the sensor type; electrochemical sensors are suitable for long-term monitoring. Check whether the detection range covers 0.01–10 mg/m³. Confirm that the instrument has calibration capabilities. Portable devices are suitable for multi-point detection, while fixed devices are suitable for continuous monitoring. Pay attention to the configuration of data storage and alarm functions.
