pH Meter Instruction Manual
1-lntroduction
The MP780647 pH Meter measures a wide range of vonductivity. Careful use and maintenance will
provide years of reliable service.
Getting Started
1-Remove the cap from the bottom to expose the pH electrode, reference junction and conductivity
electrodes.
2-Before the first use or after storage, soak the electrode in tap water or pH 4 buffer solution for
10 minutes.
3-Whlte KCL crystals may be present in the cap or on the electrode. This is to be expected depending
on the length of time in storage. These crystals will dissolve while soaking the electrode or they
can be rinsed away with tap water.
4-For best results calibrate with pH 7 buffer solution first, then calibrate with the buffer solution
closest to the expected pH value of the solution or material to be tested.
