EC Sense

ES1-AG1-1000 All-Gas / VOC Sensor

Model: ES1-AG1-1000-01

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

Ultra-compact SMD package, 0 – 1000 ppm range, all-gas VOC/TVOC-equivalent high-selectivity sensor

ES1-AG1-1000 All-Gas / VOC Sensor

The EC Sense ES1-AG1-1000-01 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; 0 – 1000 ppm range, 2000 ppm maximum overload, T90 response under 30 s and a designed lifetime over 3 years. Housed in PPO at under 0.7 g in an ultra-compact SMD package — ideal for portable detectors and space-constrained modules.
