Water Portable PH Meter , Reverse Osmosis Digital PH Tester For
PH meter is a commonly used equipment , also known as acidity meter
. Mainly used for precision measurement of the pH value of the
liquid medium , coupled with the corresponding ions , select the
electrode , can also measure the value of the ion electrode
potential MV . PH meter in the pH range of 0 to 14 used .

1 . Remove the protective cap .
2 . First rinse the electrode with distilled water , and suck it with
filter paper .
3 . Turn the meter on by pressing the “ ON ” key .
4 . Immerse the ph meter electrode in the solution to be tested ( can
not be over the immersion line ) .
5 . Stir gently and wait around 30 seconds till the reading stabilized
6 . After finished , clear the electrode with pure water , turn the
meter off by pressing the “ ON / OFF ” key .
7 . Always replace the protective cap after use .
The advantage is easy to use , free from oxidizing or reducing the
impact of material , and the equilibrium speed faster . When used,
the electrode plus liquid on the set of rubber sleeve and the
bottom of the rubber sleeve all removed to keep the electrode
within the potassium chloride solution of the hydraulic pressure
difference . The following electrode put the use and maintenance of
a simple introduction :
1 . Not in the short term , can be fully immersed in distilled
water or 1 × 10-4 hydrochloric acid solution . However , if
long-term do not, should be dry , do not wash liquid or other
absorbent reagents immersion . 2 . Before use , check the front glass bulb . Under normal
circumstances , the electrode should be transparent and no cracks ;
bulb to be filled with solution, there can be no bubbles .
3 . Measurement of the concentration of the larger solution , try
to shorten the measurement time , carefully cleaned after use to
prevent the test solution adhering to the electrode and pollute the
