Bromine read 0 - actual by test kit was 6 Ph read 7,.2, actual was 7.8 Alkalinity read 20, actual was 90

This is the second one I have purchased . The first one the battery terminal fell out the first time I changed the batteries. The second one got stuck on 8.5 PH I contacted service and was told it was to old to be replaced. They both worked well until they quite . I would recommend to a friend but would tell them not to expect it to last more than a year or two. They are an expensive device for their operating life time

I can get ph and alkaline readings but no sodium bromide reading.

I bought this less than a month ago. At first I thought i was doing something wrong. Until I only place my hand over the reader and got different results each time as well as placing several test strips and getting totally different readings every time.

Easy to use and really no more guess work with reading test strips.

I have used this product for over 10 years now. First the blue and now the red one. You must put reader in toolbox or other dark container to test accurate.

Hope it last longer than the first one .

Thought this would be the answer to testing my spa tub! Tried multiple times and know I'm not getting accurate reading of bromine!! Used three different containers of test strips I had on hand and they all had the same reading of low bromine (which I know was accurate as bromine container was out of the tub for 2 days). The TruTest claimed bromine off the chart sky high. Sooooooo frustrated. What a waste of money. NOT RELIABLE.

Did multiple tests within 5 minutes of one another. I took great care to shield the tester from outside light sources. The test strips were fresh and new. I cleaned the window on the tester between tests. Each test showed wildly different bromine measurements from none to completely saturated. The other tests were consistent. I'm back to the old strips and comparing to the label on the bottle. Consistent results that way.

The first one was all over the place. The second is much better, but when you have one test that shows bromine is OK, then the next an hour later that says it's not when no changes have been made it makes one wonder.
