works great!
a must have. this tells me my TDS out of the tap and after my DI unit (0 out tyvm!) :) make sure you install correctly. there is only 1 way to install them into the line to read correctly, so follow the directions! a must have for a reef tank ro/di unit!

Easy to install, works like a charm.
I could hardly believe how easy this instrument was to install. It must have taken me at least two minutes and it was up and running producing accurate results, I checked it with my handheld meter. The display is a little small but that's no big thing. Pun intended.😀 a great buy in my opinion.

Useful but difficult to read
This meter functions fairly well. If the two sensors don't have enough water around them in fitting they read low, so they need careful placement in T fittings. The meter output matches handheld conductivity and its inexpensive. My main issue is the low contrast LCD display that requires direct view and more than ambient light. The product concept is great and it's easy to switch from source water to RO.

Easy and accurate
Easy to hook up took 5 min tops. Have one probe on waste water and the other after the DI media. Takes the guess work out of when to change DI media!

Works
I have tested behind this product. I use the system for my salt water aquarium so water has to be randomly tested. Never had an issue.

Almost 3 weeks of use and still proving accurate,
I feel that this is VERY accurate. I purchased a reverse osmosis system and installed both the meter and the system at the same time. Before installing the TDS I tested a cup of water by dipping the prongs directly into the cup of water. It gave a reading of 144ppm. I hooked up the system and tested the incoming again and it tested 144ppm exactly. The outgoing started off at 30ppm but because of the Osmosis system being brand new I had to run it through a few times and over the course of that day it steadily dropped all the way down to 6ppm. Our system has been hooked up and used EVERY day now and its reading 12ppm, and holding roughly steady plus or minus 1ppm. I know a lot of you that read this and have done your homework on TDS will say that there was no reason to purchase the Reverse Osmosis system with a testing of 144ppm, but I wanted to be sure that with our well water that 99% of the toxins are being removed. To be honest most of the TDS reading in my water is the water softener, being that I have 3 charcoal filters before it reaches the TDS meter.

Simple to install and use
Instructions were straight forward. Took me less than 30 mins and it is working. The addition of velcro strips on the unit was good thinking by the supplier and made the finalization of the attachment easy. Great forward thinking which is often missing.I can't comment on accuracy as I have no other unit to test it against so I am trusting what it says.
