- Deluxe Dual Inline TDS Meter DM-2 - HM Digital
Well worth it By Jon S on 12/15/2014Jon S would recommend this product to a friendI was long overdue for a TDS meter and this one works very well. Easy to add into my RO/DI system and no issues so far.
Does the Job By Bradb90 on 12/14/2013Bradb90 would recommend this product to a friendI ordered this for my reverse osmosis system and it works great so far. I wish the mounting tape was a little stronger and that the green light on it wasn't so bright. I almost find it so bright that its hard to see the screen, however this product is absolutely necessary for home reverse osmosis systems.
Upgraded By Littleman on 12/10/2013Littleman would recommend this product to a friendI wanted this when I bought my bulk reef reverse osmosis plus do system, but didn't have the money . Sometimes it's good to wait because I got it for almost half the regular price. Great piece of equipment , I like the large readout. It also has easy hookup, but it needs a backlit light. I still love it compared to the tds meter that came with my system.
Great product easy to install. By Kevin on 12/9/2013Kevin would recommend this product to a friendGot this for my puratek deluxe ro/di unit somewhat redundant since it has a built in tds meter. But I wanted to see in tds and just a back up exit tds and it works great. Glad to have less than 40 tds from the tap!
Works Well By Cameron on 10/5/2013Cameron would recommend this product to a friendI installed this yesterday. Super easy and works great. Definitely good quality. Have not seen the other TDS meters to compare though.
Work good, but needs improvement By Troy on 2/27/2013Troy would recommend this product to a friendIt dose what it suppose to. IMO, if you're going to pay alittle extra then the plain duel tds, it should have alittle extra options. One, a back lit display, Two, a 3rd sensor to monitor the tds coming in to the unit would be great. But even though, it still a nice meter.
Worth the extra few bucks... By Frank on 2/19/2013Frank would recommend this product to a friendI own both the cheaper dual TDS meter as well as this delux TDS meter. The deluxe is better by far. It has better wiring, a more reliable button to switch TDS leads and a much larger screen. Spend the extra few bucks. It will most likely outlast the cheaper version in my opinion.
I had to buy another I liked it so much By Robert on 10/2/2012Robert would recommend this product to a friendI bought the 6 stage RO/DI unit and it came with this TDS meter. Then I like it so much I bought another one so I could monitor the input/output of the carbon block. It well made and works great. You can't go wrong. BRS stands behind all that I buy and are wonderful to deal with.
Simple to use By Eric W on 9/15/2012Eric W would recommend this product to a friendGreat little unit for monitoring TDS. Great way to keep track of the DI resin performance.
My only gripe is the LED is WAY brighter than it needs to be, mine is in a dark location and tends to glare so bad it's hard to read the screen. Otherwise, great monitor!
Easy to install, simple to use, and great quality. By Chuck on 8/15/2012Chuck would recommend this product to a friendThis TDS meter is great. I purchased this about six months ago from BRS and couldn't be happier. It completely takes the guess work out of when to replace RO filters/membrane and DI resin. I like having the peace of mind knowing the RO/DI is operating perfectly, and knowing exactly when it needs maintenance. Connections to install are all push fittings, and screw-mounting this is definitely the way to go. In all it took about 10 minutes to setup. It'll pay for itself after saving one set of filters and a membrane. I used to replace them all every 6-12 months, but now can know exactly when they need replacement. Thanks BRS for another great reefing tool!
Falsely Advertised By Todd on 7/19/2012Todd wouldn't recommend this product to a friendThis absolutely positively does NOT have a water resistant case. I discovered mine would not turn on. Maybe the batteries were dead. Removed the back cover to replace the batteries and discovered corrosion over quite a bit of the solder pads with condensation in the case. There is no seal along the back cover plus there is three holes in the cover for access to the calibration pots. $46 dollars wasted. Get the cheaper one.
A must for your RO system! By Charles on 7/10/2012Charles would recommend this product to a friendWorth every penny!

How is it powered? Plug? Battery?

I noticed my batteries are getting pretty low on this unit. Do you know what batteries it takes? It would be helpful to know before I take it apart. Thanks!
Bulk Reef Supply Hey Devon,
The DM-2 TDS meter is powered by 2xAA Batteries.
The DM-2 is an upgrade to the DM-1 TDS Meter:
Upgrade features include:
- Especially designed for commercial/industrial applications.
- Stronger, water-resistant casing.
- Each water line can be individually calibrated.
- Extra large, easy-to-read LCD display.
- Longer, waterproof, shielded cables.
- Variable mounting bracket.
BulkReefSupply.com suggests installing the dual TDS meter post membrane and post DI stage. These two readings will notify you when it's time to change the RO membrane and DI resin. This unit features a digital display and comes with two 1/4" John Guest Quick Connect Tee's. As with all HM-Digital products, the DM-2 comes factory calibrated.
