hmmmm..read this review:
I was excited to have a quick way to check my pool chemistry without doing drops or test strips. The drop test and strip tests can be subjective about the exact reading and color match on the charts. I wanted something the wife and kids could easily use and just read me the numbers when I was away on a trip. The Aquacheck Trutest is a great concept but I tried over and over to get two back to back readings that were close to each other (For reliabilty of data). When I tried to get the "drops" tests to match up to the Trucheck readings, they weren't even close. I took water samples to my pool supply house to determine which test type was accurate. I had them simultaneously analyze a water sample while I stood there and did two strip tests with the Aquacheck. The Aquacheck was in the ballpark on Chlorine and PH but way off on Alkalinity. We reran the tests several times and came to a conclusion that the aquacheck was off. I'm glad I verified the readings before I poured hundreds of dollars worth of chemicals in the pool trying to chase the Aquacheck readings.....I'm going back to the drops tests. YMMV

UPDATE: I contacted Aquacheck about my accuracy findings. They were very helpful and understanding and said there was a FAQ (Frequently Asked Questions) link on their website that should explain more thoroughly how to get an accurate reading. The lady said that variations in readings will occur if you wait too long to read the strip or leave the strip in the water too long.

FINAL UPDATE: After reviewing the exact procedures with the Aquachek Tech rep, I performed 5 identical tests and came up with Chlorine readings between 0.6 and 6.1, PH between 7.0 and 8.1 and Alkalinity between 95 and 185. All 5 tests were done within five miuntes of each other in our pool. I am very disappointed that the gauge is useless to me since I can't correct the water chemistry if I have no idea what the actual values are. I will give credit to the fact that the tech rep was very friendly and helpful but, that doesn't account for the $70 I (lost) paid for gauge and strips ZERO Stars


doesn't look good.. i went to the aquacheck website and there are "new and improved" instructions on how to use including doing a back flip while you're testing while standing on your head..ok..not thatttt bad..but part of it involves quickly flicking your wrist to get rid of excess water..my translation is.."damn..this thing actually isn't very accurate and we don't know how to change it to make it more accurate so can we figure a way where the results will come out pretty close each time? here's what i think..i think the gadget is water sensitive in that if the amount of water on the strip varies from test to test it will read differently. found a place i can buy one..would cost me 100 canadian for duties, shipping the gadget and 100 strips (which are only guaranteed to be good for 18 months so if i were to buy it, i'd drop that to 50 strips which should last more than one season) but i'm not going to pull the trigger on this based on a lame "new and improved instruction" sheet and no other reviews beyond this one which is scathing..
