The models MCM-300 & MCM-3000 Mineral Content Meters are designed to measure calcium carbonate by measuring the electrical conductivity of water. The Meters are battery powered using replaceable "C" size Alkaline cells and are connected to a CS-3000 inline Conductivity Electrode.  The meter ebclosures are 1/4DIN (96x96 mm) panel mount and the front of the enclosure is rated as NEMA 4 X.

The CS3000 conductivity electrodes are flat surface, high density graphite construction, they are made of CPVC material and have 1 inch male pipe threads which are designed to be used in 1 inch "T" fitting.  The flat surface does not impede the flow of water in the system and the electrodes are some what self-cleaning due to the turbulent flow across the flat surface.

The meters provide a small AC signal to the electrodes and measure the AC current which is proportional to conductivity. This signal is converted to a DC voltage and is displayed in digital form on the LCD readout.  Power from the batteries is applied through an electronic switch to the measuring circuit and is controlled by a panel push button switch, a circuit is also provided to measure and display the battery voltage (by holing the battery test switch) when the meter is turned on.  A front panel calibration adjustment is provided to facilitate calibration.
