If you have an SG7 Pro generator and want
to have the generator produce a consistent PPM it is an easy task.
There are several
variables involved in making ionic/colloidal silver. They are water
conductivity, water temperature, wetted electrode depth, electrode
spacing, generator shutoff voltage which is determined by dial setting and
the internal calibration of the generator.
Fill the container with room temperature
distilled or deionized water with a given amount of silver electrode
exposed above the water surface. Choose an arbitrary amount...an
inch for example.
The electrodes are held the same distance
apart by the epoxy casting at the top of the electrode. Do
not change the spacing.
Set the dial to HIGH with the submersible
pump in the container and running with visible water movement at the
surface. Turn the generator on. The production light will
indicate the process is underway by alternating color between red and
green twice a minute or so.
Choose a target PPM. 15 PPM for
example, as measured with the PWT meter.
Occasionally during production immerse the
meter into the water according to instructions and make note of the
reading. The readings will begin at the initial distilled water
conductivity and will continually increase as production proceeds.
When the PWT meter reads 15.0 slowly turn
the dial toward LOW until the generator shuts off. You can place a
piece of tape on the front panel and make a pen or pencil mark to show
where the dial setting is at shutoff.
You now have control of wetted depth,
spacing and the shutoff point. There is nothing more to do. Make
sure you fill the container so the wetted depth is the same each batch.
Then set the dial to the same point and the generator will produce the
same PPM each time by shutting off at the predetermined setting.
If you leave less silver exposed at the
top...or decrease the electrode spacing the generator will shut off sooner
and the PPM will be less. If you leave more silver exposed...or
increase the electrode spacing the generator will shut off later and the
PPM will be higher. You can see there are several ways to adjust
and/or control the shutoff point for consistency.
