Details: A professional Tetrahydrothiophene (THT) gas detector by FORENSICS with advanced functions that comes factory-calibrated. Tetrahydrothiophene gas detectors (THT chemical formula is C4H8S) are used to prevent exposure to toxic or harmful THT gas concentrations. Used for spot checks, restricted access, and personal safety. THT gas is utilized as an insecticide, a natural gas odorant, and a solvent in the chemical industry. High concentrations of tetrahydrothiophene exposure can cause headaches, dizziness, weakness, convulsions, and giddiness. Tetrahydrothiophene can give you stomach pain, diarrhea, and the flu. THT gas detectors are useful for anyone who may be exposed to Tetrahydrothiophene gas including anyone who will be in an environment where natural gas is present. Tetrahydrothiophene also is identified as Thiophene, Tetrahydro-, Thiophane, Thiolane, and Thiacyclopentane. OSHA does not state any PEL or TWA for Tetrahydrothiophene gas. Neither does EPA, NIOSH, nor ACGIH.

The only reference for Tetrahydrothiophene gas comes from the German body called the MAK Commission. MAK values are derived by the “DFG Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area”, better known as the “MAK Commission”. The German Research Foundation (DFG) has mandated this independent body to determine the current state of research relating to the health risks posed by substances and materials used at the workplace and to advise public authorities accordingly. MAK value = 183mg/m3 (50 ppm), peak limitation.

Included: THT Gas detector, belt clip, sling, English manual, USB charging cable, calibration cover, and USA NIST calibration certificate.
