Needed: Gas Detector and CO Detector. What do you recommend?

Hi All


I never planned or wanted to do the BPI Combustion testing but now have too. 


What products do you recommend? I obviously want to do this as economically as possible?  Thanks for any advice.

The gas leak detectors from Bacharach - the Leakator and the Leakator Jr. - are solid, good quality devices. The Tiff 8800 units are also good. Like many of these tools, it is almost always a matter of personal preference. The only issue I have with the Leakators, is that they do time-out and have to be recalibrated in fresh air. You can avoid this with the Leakator by push any of the buttons.

Two different issues with the CO detectors: 1 is ambient CO and, 2, is the undiluted CO. For ambient CO I carry a CO Experts household CO monitor. I trust it, and it reads down to 0 ppm. You can also carry one of the personal CO monitors.

For undiluted CO, the workhorse is the Bacharach Monoxor. You should contact Bill Spohn at Tru-tech tools about these things. The problem is that the CO sensor can be "fooled" by the NOx in the flue gases. So using one of the Monoxor devices, you should use a NOx filter to get accurate results. Bill says, "A CO-Undiluted (or CO-AirFree) measurement is a calculation that alters (usually raises, but never lowers) the CO reading correcting for the excess air that is diluting the CO volume concentration. To get a CO-Undiluted (or CO-AirFree) reading you MUST have an Oxygen sensor to correct for the excess air. Which usually means you use a combustion efficiency analyzer with built in CO sensor."

If the only element that you are interested in measuring (which is the case with BPI) is undiluted CO, you don't need to spend the big money that a combustion analyzer costs. But you can get efficiencies and other information with an analyzer.

The good news is that from my experience, it is hard to go wrong with the mainstream brand tools.
Thanks You,
Combustion Analyzer: Bacharach Fyrite Tech 60

Gas Detector: TIF 8900

Personal Ambient CO Monitor: Gas Badge Plus CO
Clips to your belt and never turns off. 2 year battery life.

The new BPI standards require a Gas Sniffer which has a read out of the LEL.  The cheapest I have seen was $450.00


I am new to the industry, less than 6 months. I love the mission of the industry; to bring comfort, saving, reducing the carbon footprint and most importantly, in my view, health and safety from Combustion appliances. The comfort in knowing that our referrals (customers) combustion appliances will not spill under worst case or blow up is a good thing. We all are in the home performance weatherization program, in some capacity. We talk to our referrals so they can see the payback: the gross saving over a 10 years period. So Matt, look at the payback and I will see you at the top. Their saving is your profit through referrals they forward to you. Do the Right Thing!

Best regards,

Thank you BPI
