Well the sms 122 by Milwaukee Instruments is used to Measure ph in a body of water such as an aquarium and Control co2 gas from a regulator such as a ma957 co2 regulator.
How does a ph controller work?
_____________________________________________
The sms122 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 benifits of running a milwaukee instruments ph controller?
_____________________________________________
This aquarium co2 controller will provide a stable enviroment for all of your fish tanks inhabitants. What happens is co2 will cause a drop in the ph of the water. If it is to much it can kill you 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?
_____________________________________________
Easy
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 a 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 sms 122 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
Its that simple. Any questions on ph controllers and thier application in the aquarium or hydroponic industry let us know.
