Scuba II - Electronic Pool Tester for Chlorine and pH Value from Test All Water

Excellent tester, used extensively for day2day management. From comparison checks, we found the results were very good compared to high end professional quality test equipment.

I've been using this for about a month now and it's given me consistent results across multiple tests. Very useful to keep your spa water in good shape and a good complement to test strips to make sure your "eyeball" measurements have not drifted over time (Mine had. A lot.). The interface is easy enough to get around once you have the basics down, but I highly recommend reading the short manual that comes in the box.

This product is accurate however I used it for 2 days on 3 hot tubs and the batteries needed changing. When change the battery the cover has broken as it is hard to remove the back. An expenses tool when you have to change the batteries once a week. Back to the test strips for me.

The best water tester I’ve ever used for my canine hydrotherapy pool

Straight forward to use and pretty accurate too. Nice and small compared to others available.

Have purchased 3 of these now and all have failed. They simply do not seal.

The pH readings are a bit variable. When it matters, like if the pool is starting to go green, I take three pH readings and use the middle one! Also I have stopped swirling it on the pool as it isn't waterproof. I just take a cupful of water to the instrument now. Two years using it and it seems to be going well

Not happy with check for total alkalinity to much variation in levels.This is when checked with the same sample of water. I sent my first one back for this reason, I have had the same problem with the replacement. However not as severe.
