PREPARING THE pH BUFFER SOLUTIONS
The KS-PH-221-DELUXE comes with three pH buffer packets needed for calibration.
1. Begin by opening the packet for the 7.00 buffer. Pour distilled water into a 250 ml volumetric flask up to the scale
line. Mix the solution until the reagent is dissolve.
2. Do the same for the pH 4.01 and pH 10.01 packets.
3. You will need only a small amount of calibration solution during calibration. Get the require solution from the flask
and store the rest.
4. Do not reuse used solutions.
SETUP MENU
The KS-PH-221-DELUXE has integrated set-up menus for each of the parameters it can measure. Below is a guide
