    Not really good instructions, the instruction says it’s pre-calibrated, doesn’t say anything about how often it should be calibrated didn’t send any calibration salts

    Quick, solid, easy to use, good price, functional

    It’s amazing. Easy to use and gives solid values. Might be slightly off +/- 0.215. But, it’s just what you need to get basic numbers on water sources. Thanks!

    Not accurate at all

    First, I'll say that all these tests for the price was very good. I got my tester and immediately used it on my saltwater reef tank. My calibrated meter was showing 8.0 PH and this tester showed 7.6. In the reef world, this is a huge problem. I then tested salinity. Verified with testing solution and a refractometer, my water is at 35ppt, this tester read 40/41. Again, a reading way too far off for a reef tank. I then checked into calibration and the instructions are very vague and seem to be automatic with solutions that are not easy to come by (PH asking for a 4.1 and a 9.2 solution). If the unit could be calibrated by me, I could easily us standard solutions and dial it in. Since it is automatic only for their specified range, there is no calibration to be made. Disappointed ...
