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 (four Alkaline LR44) are included in packaging.
