Reliable Conductivity and TDS monitors with Automatic
temperature compensation and 1 point manual calibration
powered by a 12 VDC adapter.
They are ideal for the hydroponic market and allow you to
continuously monitor EC or TDS values directly in your
reservoir.
Other features include: user selectable set point, visual
LED alarm when values go below the set point (for
SMS310 and SMS410).
The CAL test feature on the SMS315 and SMS415 will
warn the user (through a LED) when the probe needs to
be calibrated again!
The monitors are very simple to operate:
1
.
hang your monitor above your reservoir
2. connect the adapter to the meter and plug in the power
supply (make sure that your power supply is in a safe area
from the water!)
3. immerse 2/3 of the probe in the solution
4. the probe can now remain there permanently.
