Does ACD offer a 4-in-1 calibration blend for my confined space gas detector?
Many confined space gas detectors are configured to detect combustible gases, oxygen and one ore more toxic gases, commonly carbon monoxide and hydrogen sulfide. To meet this calibration need many cylinder manufacturers provide a 4-in-1 blend of these four gases. ACD cannot provide all four gases, but we can reduce your cost for this blend. Hydrogen sulfide is the one reactive gas in this mixture, and its presence makes the gas more expensive with a shorter shelf life. The CAL 2000 instrument can be configured to take in a 3-in-1 gas blend and then add hydrogen sulfide to it, making the 4-in-1 blend. Using 3-in-1 gas gives much better pricing per liter of gas as well as a longer shelf life. Contact your ACD representative for more information on this.
