Details: The Forensics Detectors Benzene gas detector is designed to detect the presence of benzene gas in the air and measure its concentration. Benzene gas detectors rely on PID spectroscopy to detect and quantify benzene gas in parts per million (ppm). When the level of benzene gas exceeds a predetermined limit, an alarm is triggered to alert workers of potential danger. Benzene is a hazardous chemical that can cause serious health problems and is highly flammable. It is widely used in industries such as plastics, synthetic fibers, rubber, and dyes. Benzene can also be present in gasoline and other petroleum-based products, posing a risk to workers who handle these substances.

Exposure to any level of benzene gas is hazardous to human health, and the risk increases with higher levels of exposure and longer durations. The Occupational Safety and Health Administration (OSHA) has set a permissible exposure limit (PEL) for benzene gas in the workplace at 1 part per million (ppm) over an 8-hour workday.

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