Batch download changes test parameters!!!


Having installed a whole-house RO system for medical reasons, I decided to invest in an eXact micro 20 meter so that I can monitor everything closely. But as another reviewer had already posted, the bluetooth on the meter leaves much to be desired, which automatically goes off after 6 minutes and cannot be adjusted. Moreover, whenever I download all the test results to this app, the vast majority of the tests are changed to things I didn’t even test for!!! Examples: ozone becomes chromium, free chlorine (DPD-1) becomes fluoride, combined chlorine (DPD-3) becomes copper, total chlorine becomes “high range chlorine” (CLH). And just for the heck of it, I decided to test the real CLH with a bona-fide CLH strip immediately after the the DPD-1 and DPD-3 combo for Total Chlorine, to see if the *real* CLH value actually matches the “Total Chlorine aka CLH” according to this app. And sure enough they don’t even match! Come on, Industrial Test Systems! Please don’t make us your beta testers. You know you’ve got a serious problem when writing down test results with pen and paper is far superior to this app!



I bought this app and the corresponding iDip system hoping to make water testing easier and more accurate for my salt water aquariums; unfortunately this is more difficult, has a terrible UI and Bluetooth connectivity that is nonstandard. Instead of standard one-time Bluetooth pairing, it must be reconnected time and again to try to make the device work with this app. This solution is NOT worth the money or the time it took to get it to work properly. Buyer beware.

Best ever


I love the fact that it’s one machine to do all of my salt water testing. I love the fact that it’s accurate and fast. Extremely easy to use. Highly suggest it and will never use any other type of testing equipment as long as I have this baby
