Indicating regulators feature built-in purifier.
A new series of Smart Indicating Regulators provides accurate pressure control while ensuring gas purity. A purifier built onto the regulator output prevents contamination of the gas stream and serves as an early warning of impurities. If the gas contains contaminants, of if contaminants enter the gas stream during cylinder change out, the purifier media begins to turn color. When all of the media in the purifier tube changes color, the purifier is depleted and the cartridge should be changed. The regulators also eliminate GC detector base line issues. SIR regulator users can maintain a constant base line after cylinder change out, eliminating the need to purge for hours. Airgas, Inc,
