German AMT water quality sensor hydrogen sulfide sensor - H2S sensor

I. German AMT Water Quality Sensor H2S Sensor Description:

The H2S sensor is based on the electrochemical amperometric principle and can rapidly analyze dissolved hydrogen sulfide (H2S)/sulfide in natural water on site. H2S gas diffuses through a gas-permeable membrane into the sensor, where a redox reaction occurs on the surface of the working electrode inside the sensor. Quantitative analysis is performed by recording the current signal related to the H2S content. When measuring H2S/sulfide concentration (pH 5 - 8.5), the pH value and temperature of the sample must also be measured simultaneously, and the sensor output signal is compensated electronically to correct the measured value with temperature variations (temperature compensation). This sensor is suitable for on-site measurements at water depths up to 100 meters and can also be used for laboratory testing.

II. German AMT Water Quality Sensor H2S Sensor Features:

Short response time, approximately 1 second (t90%)

High resolution, unaffected by salinity (up to 40 g/L), turbidity, and color interference

High selectivity, unaffected by gaseous substances such as CO, CO2, water vapor, CH4, and NH3

Sensor sensing head can be replaced by the user

Combines sensor slope, temperature compensation data, and mathematical formulas to calculate H2S/sulfide concentration
