Dwyer Instruments WSM-10
Waterproof Salinity Testing Pen
The Model WSM-10 Salinity Testing Pen can measure salt concentration of saltwater aquariums, determine the suitability of drinking water, and be used for ecological monitoring of aquatic habitats. This pocket sized tester is constructed of a durable ABS plastic waterproof housing and 316 SS electrodes to protect against corrosion. A large LCD display is easy to read and shows both the salinity and temperature measurements simultaneously. Since change in temperature can affect accuracy, the WSM-10 has automatic temperature compensation to achieve +/-1% accuracy. Batteries are included in packaging.
