measuring boiler PH

I went to the local pet store and picked up some fish aquariam ph test chemicals for my WMc Steam boiler. I add boiler water into a test tube with ph testing solution and match the color up to a test strip. My ph level is 7.5

    test kits for measuring boiler PH??? HELP- Dan Holohan

    I can not find any litmus paper or any other way of testing boiler PH, for under $2000, I should add. Yes there is lots of expensive equipment for this, but no litmus paper that I can find.

    Does anyone have a lead on this for me. I would like to start having my techs do this on a regular basis.
    I have tried pool supplies, but their kits don't go above 8.4 which is too low for boilers.

    Also, Dan H., if you can forward me that article you wrote recently about the importance of measureing this, I would appreciate it. Now that I want to start implementing this, of course, I can't find it.

    Respectfully,

    Litmus Paper

    Indigo.com is where I go. If you were closer, I would gladly give you some, Paul. I have more than I need.

    I bought them in all different ranges, both wide and narrow ranges to see more accurately. Sort of like having two pressure gauges with overlapping scales if that makes sense.

    litmus paper

    If you have kids in High School, or some friends who do, then you might get a couple of strips/papers from the science department. Possible listed as a science project or at home homework question. The local pool supply company probably has water test kits that do PH/chlorine testing. If you are looking for between 7-8 PH, one of their cheap kits might do the trick

    Go to George Lanthier's website, firedragonent.com. He sells an electronic ph pen for $46 post-paid

    Utility Products makes a "No-Freeze" antifreeze test strips pack that test antifreeze protection level and PH. I'm sure it would work on plain water too. I picked them up at the loca l supply house.

    Either that or you can pick up an inexpensive test kit like one would use for a hot tub. The local pool supply should have them.

    Hanna is one of the finest testers I have ever used. Make sure to get one that is ATC. Automatic Temperature Compensated. 80 coins will get one.

    pH papers

    look on the web too for "pHydron" brand pH test papers or clones thereof. Cole-Palmer, Sigma-Aldrich, VWR, Fischer Scientific, and others should have them, about $10-15 a roll IIRC. Something in the pH 6-10 range probably would be good.

    Aquarium test kits or lawn/soil test kits are another option, but probably only read pH 6-8 or so. Litmus paper (Cole-Palmer, Sigma, etc.) will only turn color below about 4.5 (turns red) and above about 8.3 (turns blue), so you lack resolution in the slightly acidic to alkaline region, but some red & some blue litmus plus an aquarium or soil kit might do the job.
  • Would a,

    simple swimming pool test kit not work?
    I use one all the time, about 6 bucks anywhere.
    Add 4 drops, turns purple or blue, you know your around 9, or higher.

    I have the ph test pen sold at Firedragonent.com, and it works great. Very inexpensive, and pretty much unlimited use. If you do antifreeze, check out the refractometor as well. I had bought a different brand before he started selling them, and I paid roughly 3 times as much!

    I don't recall an article.

    I know I talk about it in the seminar.

    I've seen electronic testers online for about $30, Paul.

    Digital pH tester

    Paul
    Test strips are OK for the casual user. They will tell you that you are in the ballpark, but for a professional I would think you would want to be in the game not just in the ballpark. Purchase a digital ATC ph meter. Two very names are Oakton and Hanna. Also purchase some calibration fluid (7.0/7.1) for calibration of the unit.
