We have been Canada's premiere industrial supplier  Specto Technology is proud to offer the Hydrogen Sulfide H2S Sensor 0-10ppm. PRODUCT FEATURES: Uses Gas Sensitive Electrochemical (GSE) technology to  Hydrogen sulfide, also known as H2S, is the rotten-egg-smelling odor that's Common effects of inhaling low concentrations of hydrogen sulfide (10 ppm or  funciones de detección tanto de CO como de H2S en un único sensor]. Los niveles de Exposición durante 10 minutos a 35 ppm y durante 5 minutos a 5 ppm:.

Once H2S is in the brain, it attacks the Respiratory Control Center. H2S seeks to shut down respiratory system or… Slow it down at lower concentrations and… It deadens your sense of smell! Never trust your nose to detect H2S.

10 ppm : Maximum exposure 10 minutes. Kills smell in 3 to 15 minutes. Causes GAS EYE and throat injury. Reacts violently with dental mercury amalgam fillings.
