OTC Microgas calibration gas
Posted to Emissions Forum on 6/3/2017 9 Replies

Hey folks, I need a little education on the proper cal gas for an OTC Microgas I just picked up. OTC lists a PN for a bottle, but it is not carried by anyone anymore and I can't find specs for the chemical mixture. Is BAR 97 gas appropriate for any 5-gas bench or does this unit require something specific for some reason? Any info is greatly appreciated.
