I'm needing a gas analyser. I haven't shopped yet ,but was wanting input from anyone who can steer me in the direction. We use argon/ oxygen and argon/co2 mixes here. Also, what would I need to detect moisture in the gas? Do they make a piece of equipment that can do all of this? I want something that can tell me what percentages of oxygen or CO2 I'm getting after the mixer and something that can detect if any moisture is in the gas. Any input would be appreciated. Thanks.
