T
he Model TDS2-10 Cond./TDS Testing Pen monitors both conductivity and total
d
issolved solids in streams, rivers, or any other body of water. It picks up impurities
and dissolved solids while checking the conductivity at the same time. 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 conductivity/total dissolved solids and temperature measurements
s
imultaneously. Since change in temperature can affect accuracy, the TDS2-10
h
as automatic temperature compensation. Batteries (four LR44 alkaline) 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:
