Details: This is聽our聽professional Mercaptan聽(CH4S)聽gas detector by FORENSICS with advanced functions that comes factory-calibrated. Mercaptan is sometimes referred to as mercaptan, methyl mercaptan,聽or methanethiol. Its chemical formula is presented as CH4S, MeSH, or CH3SH. Mercaptan聽is used as a gas odorant; an intermediate in the production of pesticides, jet fuels, and plastics; and in the synthesis of the amino acid methionine. Because methyl mercaptan is a gas a ambient temperature, the most likely exposure routes are inhalation and dermal.聽 It has pungent garlic, rotten cabbage, or a skunk-like odor.聽OSHA PEL is recommended at 10 ppm over 8 hours and聽NIOSH recommended exposure is 0.5 ppm over 10 hours.聽

Included:聽Mercaptan gas detector, belt clip, sling, English manual, USB charging cable, calibration cover, and USA NIST calibration certificate.
