Overview

The QIWEI PHS-3EB pH meter is a Benchtop microcomputer rechargeable pH measuring instrument. Measurement range is wide, covering -2 to 18pH, and the built-in battery is easy to use. The instrument uses a special sensitive film made of Glass electrode, high Sensitivity, Data storage and extraction functions, automatic temperature compensation, easy operation and stable measurement data.

Features

Measurement range is wide, covering -2 to 18pH. 2. Adopt rechargeable design, built-in battery, easy to use. 3. Glass electrode made of special sensitive film with high Sensitivity. 4. Data storage and extraction functions. 5. Can automatically perform temperature compensation. 6. Easy and simple operation, stable measurement data.

Principle

The pH Meter uses a Glass electrode (usually a composite Electrode) as an indicator Electrode. The special sensitive film on the head of the Glass electrode is sensitive to hydrogen ions, and its potential changes with the concentration and temperature of hydrogen ions after insertion into the solution. At 25 ° C, the Electrode potential changes by 59.16mV for every 1 pH change. The reference Electrode (e.g. Calomel electrode or Ag-Agcl Electrode) has a stable potential. The two constitute a measurement cell, and the relationship between the generated potential difference (Delta E) and the change in pH value of the solution (Delta pH) and temperature (t) conforms to the formula: Delta E = -58.16 × Delta pH × (273 + t ° C)/293 (mV). The instrument calculates the pH value of the solution by measuring this potential difference and through temperature compensation. The pH-3EB is equipped with a composite electricity with a pH value of 7 +/- 0.25pm.
