DM2-EC Dual Inline EC Meter

Calculated at checkout

Product Description

Install on commercial systems such as car washes, window washer, or in manufacturing or food processing facilities. The DM2-EC features digital calibration, low battery indicator, 2-year battery life, auto shut-off (3 minutes), diagnostic error messaging, and shielded sensor cables.


  • Highly efficient and accurate due to its advanced microprocessor technology.
  • Displays EC levels in two locations.
  • Auto-Off function conserves battery power. The unit shuts off automatically after 3 minutes.
  • Dual Range - Measures from 0-999 μS with a resolution of 1 μS. From 1000 to 9990 μS, the resolution is in 10 μS increments, indicated by a blinking 'x10' image.
  • Factory Calibrated with a 1413 μS solution. The DM2-EC features digital calibration.
  • Diagnostic error messaging
  • Shielded sensor cables
  • Comes equipped with quick connect fittings
  • Installs quickly and easily.

Electrical conductance is measured in siemens or mhos.  In situations with low conductivity, it is often more convenient to consider conductance in terms of millisiemens or microsiements.  A millisiemen is one-thousandths of a siemen.  A microsiemen is one millionth of a siemen.
1,000,000 microsiemens (μS) = 1,000 millisiemens (mS) = 1 siemen (S) = 1 mho (℧)
To compensate for variations in meter probe configurations, standardized EC measurements are expressed in microsiemens (μS)/cm.  The "per cm" has been removed from the DM2-EC readout to conserve space, and it should be inferred.
