Formaldehyde pollution has become an invisible threat to the modern indoor environment. From new home decoration to daily home use, its potential harm cannot be ignored. How to achieve efficient and accurate formaldehyde monitoring? Formaldehyde electrochemical sensors are the core technology to solve this pain point.

    Scientific principle: Accurately captured "olfactory" system

    Core mechanism: Formaldehyde gas (HCHO) diffuses into the sensor and undergoes an oxidation reaction on the surface of the precision catalytic electrode: HCHO + H₂O → CO₂ + 4H⁺ + 4e⁻.

    Signal conversion: The electrons released by the reaction form a microcurrent, the intensity of which is strictly proportional to the formaldehyde concentration, achieving accurate quantification of gas concentration to electrical signals.

    Stability guarantee: Built-in electrolyte maintains the reaction environment, and special filter membrane removes interfering gases such as ethanol to ensure the accuracy of core detection.

Wide application scenarios: from industrial security to home health

    Smart home: air purifiers, fresh air systems, and smart air conditioners are linked in real time to automatically purify formaldehyde.

    Portable detection: handheld detectors and smart watch accessories allow individuals to keep track of environmental safety at any time.

    Industrial security: factory workshops and laboratory environmental monitoring to ensure occupational health and safety.

    Building management: intelligent control of fresh air systems in office buildings, hotels, and schools to improve air quality.

Product recommendation:

TE08-CH2O

    Tensensor's TE08-CH2O electrochemical formaldehyde sensor uses high-precision electrochemical sensing technology, with a detection range of 0-5ppm and a resolution of ≤0.01ppm. It can accurately monitor the entire process from "slight odor" to serious formaldehyde exceeding the standard, without missing any risks.

    The sensor is a universal miniaturized design with a unique anti-interference algorithm, which effectively eliminates the interference of organic volatile gases such as alcohol, acetone and benzene, making the detection results more reliable. It also has digital output and analog voltage output for easy use.
