Models EC2-10, WSM-10, and TDS2-10 Water Testing Pens can monitor conductivity, total dissolved solids and salinity levels in streams, rivers, or other bodies of water.
October 31, 2012 - Dwyer Instruments released Models EC2-10, WSM-10, and TDS2-10 Water Testing Pens, which can monitor conductivity, total dissolved solids and salinity levels in streams, rivers, or other bodies of water. These pocket sized testers are constructed of a durable ABS plastic waterproof housing and can float if dropped. A large LCD display is easy to read and shows the conductivity, salinity, total dissolved solids, and temperature measurements. Since change in temperature can affect accuracy, the testing pens have automatic temperature compensation. Batteries (four alkaline LR44) included in packaging.
