The ME3-CH2O Electrochemical Formaldehyde Sensor is a high-precision gas sensor designed for reliable detection of formaldehyde (HCHO / CH₂O) in indoor air quality and environmental monitoring applications.
Formaldehyde is a hazardous volatile organic compound (VOC) commonly released from building materials, furniture, paints, adhesives, and insulation products. Even at low concentrations, formaldehyde can cause irritation to the eyes, nose, and throat and may pose long-term health risks. Accurate monitoring is therefore essential for maintaining healthy indoor environments.
The ME3-CH2O sensor uses advanced electrochemical detection technology to provide highly sensitive and stable measurement of formaldehyde concentrations. The sensor delivers fast response, high accuracy, and excellent repeatability, making it ideal for integration into air quality monitoring systems, environmental detection equipment, HVAC systems, and smart air purification devices.
Its compact design and low power consumption allow easy integration into OEM gas detection systems and portable air quality monitoring instruments.
