    Here's jim welsh in rich ross's secret lab looking at the prototype alk monitor.


    So does anyone know if Jim Welsh is going to scoop Mindstream on alkalinity monitoring or will this be a charitable open source semi-buy and build kinda thing.

    Jim technique is based on titration method (he mentioned using reagent), I think he just automated it. Mindstream technique is completely different. They use flourescent technology. I am sure there's a lot of pros and cons to both methods so I am kinda excited to see how they'll stack up to each other. Really exciting time ahead in the next few months for sure.

    Did I hear someone say "group buy"?
    put me down for one :D

    Been tracking this for 2+ months now with money in hand.

    Titration, nice!

    Hmm, I thought mindstream was planning to measure PH and CO2 (using IR sensor), then calculates Alk.
    As a bonus, they get Carbonate Alk that way, not just total.
    But I could be very wrong.

    I see, so one plans to use some sort of probe, you dip it in your tank and it tells you. The other is you put a water sample into some device and then it teslls you.

    I don't think you put the water sample in. I think it has a continuous feed and checks the water automatically at prescribed intervals.

    At MACNA 2016, was at the morning APEX breakfast and Rich Ross gave a small talk, mentioned this item and that he loves it. They have no idea when/if it will come to market and what the cost would be, so unfortunately don't get your hopes up. It does use special reagent and auto titrates every 15 minutes I believe with accuracy to the hundredth.

    Hmm I didn't see him at MACNA, was he only doing a talk? I did recall hearing someone talk about it (maybe it was Rich) and I did hear that you could do quicker tests it just uses the reagents up that much quicker.

    looks like its still sometime before its can be mass produced and hits the market

    Oh absolutely, no way this is coming out anytime soon

    That's genius to use the same voltage that the pH probe uses.

    I know, how smart is that. I know I've got at least 1 or 2 of the old pin point PH meters laying around in my junk drawer. They would be perfect for that.

    It doesn't use the pH probe itself just the same kind of wire.

    He is saying he can use the ph monitor as an Alk monitor.

    Ah, gotcha. I missunderstood
