Milwaukee MW301 PRO Conductivity Meter

The MW301 is a Portable Conductivity (EC) Meter with Automatic Temperature Compensation. It has been designed to meet a grower's need for equipment suited to the aggressive environments found in agricultural and hydroponics applications. 

EC testing provides a method to optimize chemical applications and minimize operational cost. In agricultural applications, soil conductivity is checked before fertilizer application to pinpoint field needs and after fertilization to establish its effectiveness. In hydroponics, EC measurement is ideal for determining the concentration of fertilizer in a solution. After determination, the grower can adjust the nutrient formula for optimal plant growth. 

The MW301 has a range of 0 to 1990 µS/cm with a 1 µS/cm resolution. This EC meter is supplied complete with a conductivity probe, which has a 1 m (3.3') cable, as well as calibration solution.
