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 (four Alkaline LR44) are included in packaging.
OPERATING INSTRUCTIONS
Introduction
Please read the manual completely before using this meter. Filing and keeping the
manual for future reference is recommended. It is also recommended to soak the
electrode for at least 30 minutes before using the meter to clear anything affecting
the probe.
Power Supply
The meter is powered by 4 LR44 button cell batteries. Check the batteries if it is
your first time use, if the battery symbol appears on the LCD, or if the meter cannot
power on.
To install the batteries:
1. Turn off the meter.
2. Loosen the battery cover in the counterclockwise direction (DON'T discard the
black washer!).
3. Replace the old batteries with four new button cell LR44 batteries.
4. Make sure the batteries are in place and the polarity is correct.
5. Put the battery cover back and turn it tightly in the clockwise direction.

use for a month or more. Do not leave batteries in the
instrument.
