HM Digital DM-1 Dual TDS Meter

Took very long time to ship product

Product is smaller than expected. Also took the company over a week to even ship the product

Very happy

The item was exactly as described and at a good price. Shipping was fast. I had a question and called Fresh Water Systems and they quickly passed me up to a person who had the answer. Highly recommended.

Good System

A great little system for monitoring water quality, I use 2 of them together. One for RO and one for DI See photo.
