Features:
A pH meter is an electronic device used for measuring the pH which is either the concentration of Hydrogen ions in an aqueous solution or the activity of the Hydrogen ions in an aqueous solution. The pH will indicate if the solution is acidic or basic, but is not a measure of acidity or alkalinity. pH meters work in liquids though special probes are sometimes used to measure the pH of semi-solid substances. A pH meter consists of a special measuring probe (a glass electrode) connected to the body which measures and displays the pH reading.

Users Guide:
Instrument power supply for 9V alkaline batteries, open the instrument at the back of the battery cover, into the batteries. Instrument before use, namely measuring solution pH value, before to correction. But not before each use will correction, general when measuring interval time is short, weekly correction only once. Instrument using threecorrection way, specific steps are as follows:
| (1) | press the "switch" button, switch on the power, the instrument into the normal state of measurement; |
| (2) | according to the "mode" button instrument into the correction state, respectively into "C4.0" "C6.86" "C9.18" three states cycle scintillation indicating symbol. |
(3) | Correction steps are as follows: (please at 25 C ± 1 C environment do the correction work) A: PH4.0 solution correction: press the "mode" button instrument into the "C4.0" scintillation status, electrode with distilled water cleaning, will electrode in the PH4.0 solution, for 20 seconds, the purpose is for electrode is stable and at this time, hold "CAL" button 3 seconds dont put," C4.00 "scintillation disappear, at this time PH4.0 solution after correction. Then click "model" key exit. B: PH6.86 solution correction: press the "mode" button instrument into the "C6.86" scintillation status,electrode with distilled water cleaning, will electrode into PH6.86 solution, for 20 seconds, the purpose is for electrode is stable and at this time, hold "CAL" button 3 seconds dont put," C6.86 "scintillation disappear, at this time PH4.0 solution after correction. Then click "model" key exit. C: PH9.18 solution correction: press the "mode" button instrument into the "C9.18" scintillation status, electrode with distilled water cleaning, will electrode in the PH9.18 solution, for 20 seconds, the purpose is for electrode is stable and at this time, hold "CAL" button 3 seconds dont put," C9.18 "scintillation disappear, at this time PH 9.18 solution after correction. Then click "model" key exit. |
(4) | normal measurement mode: Boot the default in normal measurement model. Normal measurement model can simultaneously measure the PH value and environmental temperature. PH value measurement model shows "P" + numerical. temperature display degrees celsius. |
| (5) | when the instrument screen display left blank battery symbol, please replace the battery. Instrument long-term dont please take it out. |
In the following circumstances, Instruments Must be to correction:
| (1) | solution temperature and correction of temperature have great changes; |
| (2) | leave solution time too long electrode; |
| (3) | change with the new composite electrode; |
| (4) | measurement concentrated acid (pH < 2) or strong alkali (pH > 12) after; |
| (5) | measurement contains fluoride solution and acidity in pH < 7 solution or thicker after organic solution. |
| (6) | correction, please will PH correction fluid in 25 ± 1 C temperature environment. |
