Five-gas comes of age.
PIDs and a range of electrochemical sensors have become commonplace as extra sensors in conventional 4-gas confined space entry meters to protect workers from exposure to a broad array of toxic organic and inorganic vapors. New wireless transmission systems have opened up a host of safer and faster detection capabilities, requiring less operator involvement and thus saving costs.
