Details: The professional hydrogen (H2) gas meter by FORENSICS. Detecting hydrogen gas in vehicles, fuel cells, storage tanks, laboratory settings, or outgassing from batteries. H2 is a colorless, odorless, and tasteless gas which makes it very important to adopt detection instrumentation. It is the lightest gas and explosive in the air over 4%. When in contact with chlorine, oxygen, or other oxidizers, hydrogen is flammable and burns with a nearly invisible flame. Our H2 gas detector has high precision and provides robust measurements for fieldwork, inspections, occupational safety, industrial, and environmental applications. The instrument employs a high-quality electrochemical sensor.

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