MW301 Standard Portable Conductivity Meter

MW301 is a Conductivity Portable Meter, with Automatic Temperature Compensation, and is ideal for the educational and agricultural markets. Soil conductivity is checked before fertilizer application to pinpoint field needs and after fertilization to establish its effectiveness. The EC testing provides all agricultural operation with a method to optimize chemical applications and minimize operational cost.

This instrument has been designed to meet the Grower's need for equipment suited to the aggressive environments found in agricultural and hydroponics applications.

The MW301 has a range of 0 to 1999 μS/cm with a 1 μS/cm resolution. The meter is supplied complete with Conductivity probe with 1 meter cable and calibration solution.
