SGX Sensortech SGX-4DT Miniature Dual Carbon Monoxide / Hydrogen Sulfide Sensor

Introducing SGX Sensortech SGX-4DT
Miniature Dual Carbon Monoxide / Hydrogen Sulfide Sensor
Electrochemical Sensor Available at CDI
   
SGX Sensortech’s SGX- 4DT is a dual electrochemical sensor available in an industry standard mod 4 housing. SGX electrochemical sensors detect gases by producing a chemical reaction between the gas and oxygen contained in the sensor. This reaction produces a small current, which is proportional to the concentration of the gas present. SGX electrochemical sensors are designed to measure carbon monoxide and hydrogen sulfide in the parts per million range. This allows measurement of these gases in concentrations in the occupational exposure range that, for example, are 5 and 10 ppm for hydrogen sulfide for the 8 hour and 15 minute limits respectively. The outputs of SGX’s electrochemical toxic sensors (when run in a simple potentiostatic circuit as described in Electrochemical Sensors Application Note 2) are between 55 and 850 nA per ppm of gas.
