Product Description:
YJJ NE4-HCHO-S Type Electrochemical Formaldehyde Gas Sensor
Features:
NE4-HCHO-S electrochemical formaldehyde gas sensor is specifically designed for precise detection of formaldehyde. With its unique parameter performance, it plays a crucial role in various fields. The following will detail its various parameters and their corresponding uses.
Detection range: 0 - 10 ppm. This range is set to meet the needs of indoor air quality monitoring and the detection of low-concentration formaldehyde in most industrial scenarios. In indoor environments such as homes, offices, and schools, the formaldehyde concentration safety standard is usually in a relatively low range. This detection range is sufficient to accurately detect whether formaldehyde exceeds the standard and ensure the health of people. For example, in newly renovated houses, due to the release of formaldehyde from decoration materials, the sensor can continuously monitor within this range, providing reliable data for residents to determine when it is suitable to move in. In some industrial production processes with strict restrictions on the use or emission of formaldehyde, such as wood panel processing and certain chemical product manufacturing, it can also effectively monitor the formaldehyde concentration, ensuring that the production process complies with environmental protection and safety regulations.
Maximum overload: 50 ppm. This indicates the highest formaldehyde concentration that the sensor can withstand. This parameter ensures that the sensor will not be damaged due to a sudden high concentration shock in environments where the formaldehyde concentration temporarily rises abnormally, maintaining normal operation and measurement accuracy. For example, at an emergency site for formaldehyde leakage handling, the formaldehyde concentration in a certain area may spike temporarily, and the sensor can tolerate this for a certain period of time, providing valuable concentration data support for rescue and subsequent handling.
Sensitivity: 500 ± 150 nA/ppm. The sensitivity is extremely high, meaning it can respond to very small changes in formaldehyde concentration. Even if the formaldehyde concentration in the environment only has a slight fluctuation, it can precisely reflect through the current change, thereby achieving high-precision detection of low-concentration formaldehyde. In places with strict air quality requirements such as hospitals and kindergartens, it can promptly detect the subtle changes in formaldehyde concentration and take measures in advance to avoid harm to sensitive populations.
