Formaldehyde Monitor

The formaldehyde detector measures the concentration of formaldehyde in the air using an electrochemical sensor. The instrument draws in an air sample, and the sensor generates an electrical current signal proportional to the formaldehyde content, which is then converted into a numerical reading by the circuitry. It is used for monitoring formaldehyde levels in indoor environments, furniture, and building materials, helping to assess air quality conditions.
Selection
When selecting, pay attention to the sensor type, as electrochemical sensors offer better stability. Check whether the detection range covers the commonly used interval of 0.00–10.00 mg/m³. Note the calibration cycle and method of the instrument, with portable models being suitable for on-site detection. Consider the response time and data recording functions to meet the needs of different usage scenarios.
