EC Sense

ES4-AG1-200 All-Gas / VOC Sensor

Model: ES4-AG1-200-01

VOC / All-Gas Solid Polymer Electrochemical (3-electrode amperometric)

Standard package, 0 – 200 ppm range, all-gas VOC/TVOC-equivalent high-selectivity sensor

ES4-AG1-200 All-Gas / VOC Sensor

The EC Sense ES4-AG1-200-01 uses solid-polymer electrochemical technology and is essentially an "All-Gas" sensor — equivalent to VOC/TVOC detection. It responds to a broad spectrum of volatile and toxic gases including carbon monoxide, hydrogen, ammonia, hydrogen sulfide, sulfur dioxide, nitrogen oxides, ozone and phosphine, making it a low-cost electrochemical alternative to VOC sensors and PIDs. Calibrated with CO and Isobutene; 0 – 200 ppm range, 1000 ppm maximum overload, T90 response under 30 s and a designed lifetime over 3 years. Standard ABS housing at about 6 g, easy to integrate via pin soldering into conventional gas-detection modules.
