Product Description

Product Description: How Pure is Your Water? HM Digital's DM-1 is a dual inline monitor that measures TDS from 0 to 9990 ppm. It includes batteries, two sensors and two 1/4" quick-connect T-fittings. The DM-1 is an easy and convenient method of determining TDS levels for water filtration/purification systems such as reverse osmosis (RO), deionization (DI) and more. It's very useful for coolers or under-the-sink systems. For any type of system that removes TDS, you can install the 'IN' sensor on your tap water (before the system) and the 'OUT' sensor on your product water (after your filtration system) to determine the filter/membrane's effective operating (rejection) rate.

Expert Review

Review by: Kate M.
I order products online every once in a while but occasionally you don’t get what you thought you were buying. This time it as a good deal.

The first thing that came to my notice was the design. I rarely saw merchandise, a model like this at a web shop. So to tell you the truth, I came to like the stuff the moment I saw it. Though I I had my doubts about the quality when I was buying it. My previous experience told me I’d better not expect good quality. Glad I happened to be wrong.

When my package arrived I was amazed by the quality of the stuff. Personally for me, it isn’t often that you get, obtain, run into such thing made of fine materials. the merchandise turned out to be a fine deal! it’s good I got it. I didn’t expect I’d get something of this quality at a web store. I discovered several similar items from other sellers but it wasn’t really anything of decent quality. Either the appearance or the quality appeared too cheap so was discouraged to buy it.

I was looking for a gift for my partner and I was fortunate I got this item. They say the merchandise is pretty popular among certain people. My soul mate has been using it for some time now and looks very happy. So I believe I was lucky to encounter this web site.
