I received a defective one. It just decides to start working out of the blue and then stops out of the blue. When it decides to get going it seems to read well. I tested it beside the blue dye and they came out relatively the same which is good but for 10 tries I would get zero and only the temp probe worked and then it would just magically work for 30 seconds.

I just started to use hydrogen water bottle and felt like it may not have been doing it’s job and wanted to test it. Bought this but would have like some information of what each setting means. Comes with absolute no documentation and had to look online to figure out what each setting meant

This works very well. As typical values of my hydrogenated water I get between 1200 and 1600 ppb. It is in daily (hourly) use with me now. I highly recommended it. Instructions are scanty but button layout is obvious. After 100 days of use suddenly within two weeks' time the values measured dropped to 300 to 500ppb. At first I thought the Hydrogen water bottle was faulty but I was wrong. I dipped the tip of the tester into 3% Hydrogen Peroxide (H2O2) for 3 hours. After that the tester measured correctly 1200 to 1600ppb again. There must have been a biofilm or corrosive layer on the electrodes. Once that was removed by the Peroxide everything was back to normal.
