Product Introduction

        ND-3200 Direct Reading Salt Density Meter is specifically developed for pollution flashover detection in power systems. It is a dedicated measuring instrument used to determine the equivalent salt deposit density (ESDD) on insulator surfaces, while also capable of measuring solution conductivity and temperature. With features such as high measurement accuracy, intuitive readings, wide measurement range, and user-friendly operation, this device is widely used in power utilities, education, scientific research, and other related industries.

Product Features

☆ Automatic range switching function.
☆ Wide measurement range: ESDD range 0.0001 mg/cm2 to 9.9999 mg/cm2.
☆ Automatic temperature compensation, directly displays standard conductivity and ESDD at 20°C.
☆ Automatically eliminates the inherent conductivity and original salt content of cleaning solutions with conductivity greater than 10 μS/cm, reducing requirements for cleaning solutions.
☆ Converts ESDD measured under non-energized conditions to ESDD under energized conditions using a live-line correction coefficient.
☆ Data storage and printing function, capable of storing 400 sets of data.
☆ Built-in high-capacity rechargeable lithium battery, suitable for field use.
