- Deluxe Dual Inline TDS Meter DM-2 - HM Digital
Work good, but needs improvement By Troy on 2/27/13Troy 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 2/19/13Frank 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 10/2/12Robert 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 9/15/12Eric 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 8/15/12Chuck 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 7/19/12Todd 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 7/10/12Charles would recommend this product to a friendWorth every penny!
Excellent piece of equipmemnt By Alexa on 5/27/12Alexa would recommend this product to a friendThis device is almost perfect with a few minor issues:
1. the tape doesn't stick well to the wall and I eventually just permanently mounted it with screws after it fell off the wall a few times.
2. The auto-shutoff is way too short.
However, an excellent device otherwise.
Works great By James on 2/24/12James would recommend this product to a friendWorks good, comes calibrated which is great. Ive been useing it in on my bathroom wall and it hadles moisture no problem.
very durable and easy to use. By kevin on 8/2/11kevin would recommend this product to a friendway better quality than I expected for the price
Great product By Todd on 3/31/11Todd would recommend this product to a friendI purchased this from BRS about a year ago now and I figured I would submit a long term review. If you are a reefkeeper and want to ensure the absolute purest water for your critters then this product is an absolute must IMO it tells you if your system is working correctly by telling you how much particulate is in your water on a microscopic level. Without it its a guessing game. I installed mine after the membrane and after the DI cartridge. I am planning on getting one to put on my water supply and after the sediment filters as well in the future. Water quality is the first building block in a successful Reef Tank. If you are real serious about the hobby how can you go without it? This and the filter miser with volumizer also by HM digital and available at BRS are the dynamic duo in water quality and monitoring. If only buying one at a time go with the TDS first.
Thanks again BRS for providing a one stop solution to Reef Keeping you guys rock.
