Need Help Calibrating Ph Probe

[JARRETT SHARK]

I Have A Milwaukee Sms 122 Ph Meter

I Bought It Used And Have No Idea How To Calibrate It

I Do Have Ph Solution 4.000 , 7.000 , 10.000

Just Don't Want To Waste The Solution

Thanks Kathy But Just Want To Make Sure That I Am Using This Probe For My Calcuim Reactor And I Should Use Solution 4.000 And 7.000 ?

I know less than nothing about calcium reactors, but after a really quick read through the attached article, it seems that a properly calibrated PH probe is necessary to adjust the reactor.

From American Marine Pinpoint Monitor

For maximum performance the PINPOINT pH Monitor should be calibrated immediately. Proper calibration requires the use of 2 different fluids; one of which must be #7.00. Any combination of either (#7.00 and #4.00) or (#7.00 and #10.00) will give equally excellent results.

use 4 and 7 if you are using calcium reactor. it would be more fine tuned to lower ph that will be in the effluent
