The MDM-25A is a Portable electromagnetic conductivity/concentration meter and can be a field operated Instrument for measuring conductivity in applications where typical conductivity cells cannot be used due to the sample conditions.
Highly acidic or Alkaline solutions can be easily measured with the sensor constructed of PVC or PFA. The Principle of the sensor uses electromagnetic induction and can measure high concentration values.
The unit is capable of measuring conductivity at depths of up to 10 meters. The LCD display shows all appropriate parameters, has minimal maintenance and does not require daily calibration.
