DM-2-03 TDS Monitor
The DM-2 is a commercial-grade monitor measuring TDS feed (input) water vs. product (output) water of a
water filtration system at any time. With its shielded cables and diagnostic messaging this robust device is
ideal for Reverse Osmosis (RO), Deionized water (DI) filtration systems that work well in applications such as
drinking or potable water, Water treatment, Aquariums, Hydroponics, and more.
Specifications:
• Comes with 3/8" quick connect fittings
• Installs quickly and easily
• Diagnostic error messaging
• Shielded sensor cables
• Measures from 0-999 ppm with a
resolution of 1 ppm.
• Auto-off function automatically shuts
off meter after 3 minutes of non-use to
conserve battery power
• Displays TDS levels of the feed water
and product water with in and out
electrode probes
• Measures from 1000 to 9990 ppm with a
resolution of 10 ppm indicated by a blinking • Factory calibrated with a 342 ppm
"x10" image.
NaCl solution. Meters can be digitally
recalibrated.
• Highly efficient and accurate due to its
advanced microprocessor technology
• Includes 3/8" Quick-Connect T-fittings

Stainless Steel Membrane Housings
Attractive stainless steel vessels enhance system appearance and allow you to
take full advantage of membrane capability. These are safer and more reliable
than PVC pressure vessels. The style of our stainless steel vessels is designed
for direct connection to Nelsen and Filmtec/DOW style elements. Includes
stainless steel housing, end plugs and pins.
