Specifications

The Smart pH monitor allows you to continuously monitor
pH values directly in your reservoir.
Features include: user selectable set point (for SMS110 and
SMS120), visual LED alarm when values go above the set
point and manual calibration.
The SMS115 with the Cal-test button will warn the user when
the electrode needs to be calibrated again.
Each monitor is powered by a 12 VDC adapter and is ideal
for applications such as Hydroponic and Aquarium.
The pH monitors are very simple to operate:
1. hang your monitor above the 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
away from the water);
3. immerse 2/3 of the electrode in the solution;
4. the probe can now remain there permanently.
The SMS110 and the SMS120 are supplied complete with
a MA911B/2 pH electrode, the SMS115 with MA912B/2 pH
electrode.
Each monitor comes complete with a 12 VDC adapter and
calibration solution.
