How does a pH
The SMS122 or
MC122 works on a simple principle. What
it basically does is turn off CO2 gas from a regulator with a solenoid once a
set point is reached.
What are the
benefits of running a Milwaukee Instruments pH controller?
CO2 controller will provide a stable environment for all of your fish and other
aquatic animals. What happens is CO2
will cause a drop in the pH of the water.
If it is too much it can kill your fish and other animals. If you use something like this unit it helps
maintain a stable pH in your tank.
How do we set
the SMS122 pH controller up?
1. Plug in
both power cords to the wall.
2. Turn unit
on and calibrate the unit following the instructions using the calibration
solution for the unit.
3. Place the
probe in the water.
4. Plug in
your CO2 regulator power cord (hopefully an MA957 by Milwaukee Instruments, but
any 110V unit with a solenoid will work) into the back side of the second plug.
5. Make your
set point. This is the point where you
want the SMS122 to turn off. 7.0 will have
the MA957 CO2 regulator gas turn off @ 7.0 and back on @ 7.1 and back off @ 7.0
simple. Any questions on pH controllers and their application in the aquarium
or hydroponic industry let us know.
