Review on 🔬 Accurate and Reliable TDS Water Quality Test Meter with Large Backlit LCD Screen, Professional TDS and Temperature Measurement at an Affordable Price. by Cesar Danger

It's hard to buy one from Revain as there are so many of them, many of which are the same item at different prices. I bought this device because of the reasonable price, reasonable reviews and a seemingly reasonable company. The company has been as good as it gets, the product works very very well and seems worth what they are asking. I use this to ensure my home reverse osmosis system is working. Initial tests show that the tap water here is around 150ppm and the reverse osmosis water is around 10ppm, so it's all working very well. I should point out that while I'm usually very concerned about accuracy, this is a case where it doesn't matter. . If the unit varies even +/- 20%, the results would still work for me (i.e. 8-12 variation). This still means everything works and multiple number variants mean nothing. The main thing is that it works and it works. Easy to read and temperature compensated. Temperature compensation is quite important as our tap water fluctuates wildly from summer to winter (from 30 to over 60) and this can be a much bigger issue than accuracy. I don't know how long that will take. but now I'm glad I got it.
