The Potassium hydroxide (dyed red) in the Bacharach Fyrite Gas Analyzer C02needs about an inch more. Instructions say to add a water drop at a time..will that be ok …it will be more than a few drops..will it get diluted? where can I get some of this stuff…seems like i've seen pellets sold and am looking for proper mixture.

    This is the tune up / repair kit for your wet kit bottle

    Look for an online source. RE Michel has only 4 left company wide. Johnstone Supply does not have a listing any more. Try Sid Harvey or other sources.

    After you make that expensive repair and you still have the same problem, What will you check next?

    the red "dye" is a ph indicator. as long as it is still red after you add water there is enough KOH available in the solution to absorb the CO2 from the gas.

    you could make your own with KOH crystals and I think the red is phenolphthalein

    Yes..trying to figure that formula out for correct mixture. Thanks

    ok Mattmia2…from the bottom of unit at the point where the black plastic on top ends this is the water line in the unit. I would have to add about an inch of water to reach the point in tube where the zero line starts. I just thought that it would dilute it too much. I think that the color will remain the same with that small addition of water. The instructions say tap water is fine. I just got thrown off with the book saying add drops.

    I think the percentages are in the msds but essentially there just needs to be an excess of KOH so it will absorb all of the CO2

    I have added a full ounce of water to that solution and found the measurement to be accurate with one that is freshly rebuilt with the diaphragm, gaskets and new bottle of the chemical.  

    I also find that when the chemical is almost spent, you can get a few more tests out of it by mixing the CO2 sample several more times. The instructions say invert the bottle 2 times to get a good mixture of the gas sample with the fluid. When you are at the end of the solution's useful life, just mix the sample 3 of 4 times. Every time you mix, the fluid rises a bit more. After you mix it one more time and the fluid does not rise in the tube, that is your CO2 reading.

    When you are doing up to 20 tests a day (maybe two to four tests on several customers a day) You find out about these little tricks.
