Product Description

Product Description

ES4-HCHO-100 Formaldehyde Gas Sensor

The ES4-HCHO-100 is a high-performance formaldehyde gas sensor designed to deliver accurate, reliable, and fast detection of formaldehyde (HCHO) in various environments. Using solid polymer electrochemical sensing technology, it is an ideal solution for monitoring indoor air quality, industrial safety, environmental monitoring, and ensuring compliance with safety regulations for formaldehyde exposure.
This sensor is particularly effective for applications that require precise detection in both low and high-concentration environments, providing fast response times, low power consumption, and high sensitivity.
Key Features

• High Sensitivity: The ES4-HCHO-100 sensor delivers a sensitivity of 35 nA/ppm ± 20 nA/ppm, ensuring precise measurements even at low concentrations of formaldehyde.
• Fast Response Time: The sensor offers a rapid response time of T50 < 20s and T90 < 120s, making it ideal for real-time monitoring.
• Wide Measurement Range: It can measure formaldehyde concentrations in the range of 0 to 100 ppm, with a maximum overload of 200 ppm, providing flexibility for different applications.
• Lower Detection Limit: The lower detectable limit (LDL) is ≤ 5 ppm, allowing the sensor to accurately detect even trace amounts of formaldehyde in the air.
• Long-Term Stability: The sensor shows long-term drift of less than 1% per month, and it has an expected lifetime of over 3 years in ambient air.
• Zero Drift in Clean Air: The sensor exhibits zero drift of less than 0.2 ppm in clean air, ensuring reliable and stable performance over time.
• Minimal Cross-Sensitivity: The sensor shows minimal interference from other gases like CO2, NH3, CH4, and ethanol, ensuring that it provides accurate formaldehyde measurements without false readings.
