- TOXIC GAS: Hydrogen sulfide is a deadly risk to humans, animals and even vegetation. Read more here. - FLAMMABLE: It is also a fire danger. - REGULATED BY THE EPA: The United States Environmental Protection Agency strictly monitors and enforces measures to prevent hydrogen sulfide gas from impacting the environment.

These kinds of sensors can be used over a large measuring range, up to 50 vol% ethanol and more, with a high sensitivity. In the range from pH 7.4 to 4, the pH value had no influence on the sensor signal. Higher salt concentrations can slightly influence the measurement. The detection limit amounts to 0.06–0.65 vol% ethanol.

Testo 316-3. The new Testo 316-3 heated diode refrigerant leak detector, delivers optimal sensitivity to all CFC, HCFC, and HFC refrigerants, detecting leaks as small as 0.15 oz/year. By design the 316-3 is resistant to contaminants such as dust, dirt and oil.
