ExcelPure TDS Handheld TDS Meter with 3-Button Digital, Carrying case for Household Drinking Water,Aquarium Pool, Swimming Pools (0-9990 ppm Measurement Range; 1 PPM Accuracy)

Easy to read. Instructions are a little basic and packaging was very simple. I was hoping there'd be more information/education about what the meter would read and what's good or bad (there is basic information). It does come in a nice leatherette case. We tested our regular tap water, RO drinking water and bottled water - seems to be correct. Will come in handy for spot checking our RO system.

Good meter. Easy to use. Does the job.

It appears to work but was disappointed that the photos are misleading, The unit is actually a tan color, not white at all. Just looks like the old ivory electric switch plate color... looks like it's 20 years old.

ExcelPure TDS is well made, way to use.

Bought this one to help my husband to track our undersink RO system filter`s usage, which works just as expected. We will keep using it to check the water quality every two weeks since our filters have already passed the "replace every six month" period. Just remember to dry the probes before stash it. Well, it is working as expected, fast delivery and we both like it.
