pH METER

Make: Systronics

Model:pH meter 361

Specification:

pH Range: 0 to 14.00 pH

Principle

A pH meter provides a value as to how acidic or alkaline a liquid is. The basic principle of the pH meter is to measure the concentration of hydrogen ions. Acids dissolve in water forming positively charged hydrogen ions (H+). The greater this concentration of hydrogen ions, the stronger the acid is. Similarly alkali or bases dissolve in water forming negatively charged hydrogen ions (OH-). The stronger a base is the higher the concentration of negatively charged hydrogen ions there are.

Application

To check the pH value of different solutions.

User instructions

1. Electrode shall be rinsed between samples with distilled – ionized water.

2. Never WIPE or RUB the electrode with tissue paper ---wiping can cause erroneous readings due to static charge. Just blot the end of the electrode with lint free paper.
