Sensor Increases Detection Sensitivity of Ammonia Gas
Effectively Detects Ammonia Gas ConcentrationThis gas sensor detects ammonia gas by utilizing a highly electron mobility transistor (HEMT), a device used to amplify or switch electronic signals and electrical power. Ammonia gas is used to reduce nitrogen oxides (NOx) through selective catalytic reduction (SCR) to prevent acid rain and smog formation....
