This PH meter is a small and exquisite pen designed to measure the PH of pure water production, tap-water, well water, seawater, electroplate liquid, boiler water, urine and so on. It also can be used in the areas of fish tank, swimming pool, photographic rinses, lab, aquaculture, food processing, dyed hair enzymes, cosmetic, etc.
The screen of this kind of pH meter is equipped with backlight LCD, which makes it easier to read in the dark. Above all the measurement accuracy of this PH meter is 0.01, so the measurement is more accurate.

1.Remove the protective cap.
2.Clean the electrode with distilled water, and then dry it with filter Paper.
3.Turn on the pH meter by ¡°ON-OFF¡± switch located on the top of battery case.
4.Immerse the pH meter electrode in solution up to the immersion level. Under no circumstances immerse above display level.
5.Stir gently and wait for the reading to stabilize.
6.After use, turn it off, use the distilled water to clean the electrode and place the protective cap back.
Immerse the electrode in pH 6.86( under the temperature of 25 degrees Centigrade) standard buffer solution of phosphate, and gently shake the electrode.
Regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained.
Immerse the electrode in pH4.01 or pH9.18 the standard buffer solution of borax.
After about one minute, until the buffer solution value corresponding to the measurement temperature is obtained.
The pH range of the instrument must be re-calibrated in the following conditions:
The electrode has been used (laid) for long time from the last calibration.
The electrode has been used in particularly taxing conditions.
The utmost accuracy is required.
