Nice!

Great little meter. Simple hook up and easy to read/use. Honestly I don't see myself using this often, but it is worth the money to check your filter once in awhile to make sure it is working. 185ppm in, 5ppm out for my house (97% rejection).

RO/DI monitoring

I've had two five stage RO/DI units, but haven't had dual TDS meter on either units. Wow, what I difference you can tell easily what the water quality is coming in and out as production water. Take the guess work out of filter changing. I install the meter in 5 minutes, pretty straight forward. If you don't have one on your RO/DI unit you don't know what your missing. Highly recommended.
