Product Description
EC-Sense ES1-H2S-100 Hydrogen Sulfide Gas Sensor
The EC-Sense ES1-H2S-100 is a solid polymer technology gas sensor designed for the detection of Hydrogen Sulfide (H2S). It offers extreme linear response up to high concentrations, low noise, and a short warm-up time. With no electrolyte leakage and a low cost at large volumes, this sensor is ideal for various applications including water treatment plants, biogas applications, portable and fixed point monitoring, and leakage detection. It is individually calibrated and includes a test report.
