DM-2 Dual Inline TDS Meter Video Transcript
Hey everyone, Aquaman here with FilterDoctor.com. Today weíre looking at the HM Digital DM-2.
The DM-2 is a commercial grade dual inline TDS meter. It has two sensors so that you can measure both the incoming and the outgoing water; and then, of course, get the readings on this LCD screen.
The DM-2 is waterproof and has longer cables than the DM-1; it is a little bit more robust and more appropriate for commercial and industrial applications. It is pre-calibrated from the factory, but can be re-calibrated, using a 342 part per million sodium chloride solution, which is available from HM Digital.
It has an extremely long life battery; you can expect approximately 1 to 1.5 years life out of the battery. And, of course, an auto shut off feature, thatís pretty typical for meters like this so that battery life is extended.
Now, this is perfect for any situation where you want to know both the incoming and the outgoing TDS. Maybe you have a reverse osmosis in a car wash and you want to know how much TDS reduction youíre getting. Well, you wonít know that if you donít have both the beginning number and the outbound number after the filter system. Thatís why you need a dual inline meter like this.
And there are many many other applications where you need to know both of those numbers. And then simply do some math and determine what percentage of reduction am I getting from my system. In some cases it will tell you that you need to replace your reverse osmosis membrane, in other cases it will tell you that the DI resin is exhausted and needs to be replaced.
Again, this is the DM-2 from HM Digital, and Iím your host Aquaman with FilterDoctor.com.
