The ES1-HCHO-5 Formaldehyde Gas Sensor is a high-performance, solid polymer electrochemical sensor designed for detecting formaldehyde (HCHO) gas in various environments. Utilizing advanced amperometric sensing technology, this sensor offers high sensitivity, with a sensitivity of 35 nA/ppm ± 20 nA/ppm, and a wide measurement range of 0-5 ppm, making it ideal for applications such as indoor air quality monitoring and TLV (Threshold Limit Value) monitoring.
It boasts fast response times with T50 under 20 seconds and T90 under 120 seconds, ensuring quick detection of formaldehyde levels. With a low detectable limit of ≤ 0.05 ppm and a linear response up to 5 ppm, the sensor ensures reliable and accurate measurements even in challenging conditions.
The ES1-HCHO-5 operates in a wide temperature range of -20 to +55°C and a humidity range of 15-95% RH (non-condensing), providing flexibility for use in diverse environments. It features a long expected lifetime of over 3 years in air, and minimal drift (less than 1% per month), ensuring consistent and dependable performance.
Designed for ease of integration, the sensor is housed in a compact, lightweight PPO material, with a weight of less than 0.7g. It is individually calibrated and comes with a test report for quality assurance. This sensor is an excellent choice for industries and applications requiring precise and efficient formaldehyde gas detection at low cost, offering low noise, no electrolyte leakage, and minimal maintenance.
