Diffusion formaldehyde Detector

The diffusion-type formaldehyde detector utilizes the free diffusion of gas to the sensor, generating an electric current signal through an electrochemical reaction, where the magnitude of the current is proportional to the formaldehyde concentration. It is used for rapid on-site measurement of formaldehyde levels in indoor air, offering simple operation but being susceptible to interference from temperature and humidity.
Selection
When selecting, focus on the sensor type, with electrochemical sensors offering better stability. Ensure the measurement range matches common indoor formaldehyde concentration levels. Check the product's calibration cycle and temperature-humidity compensation features. Confirm the response time and recovery time parameters. Understand the sensor's lifespan and replacement costs.
