PH Sensor Toshcon Glass 1 Meter Cable

The and Construction of pH meter Probe, PH Sensor Toshcon Glass 1 Meter Cable

Other Product in thie catagory: pH Sensor/ pH Probe / pH Electrode

1. pH Sensor 1 Meter cable Toshcon Brand (Glass Type). Hence pH sensor also called by peoples as pH Probe or pH Electrode. Hence all Pronounce are same.
2. pH Sensor 3 Meter cable Toshcon Brand (Glass Type)
3. pH Sensor 5 Meter cable Toshcon Brand (Epoxy Coated / Unbrackable)
4. pH Sensor 10 Meter cable Toshcon Brand (Epoxy Coated / Unbrackable)

Constroction pH Sensor

1. Glass bulb: It is a sensor that senses the H+ ion concentration and it is made from special type of glass and membrane. The glass bulb consists of 0.1 M HCL Solution.
2. Internal electrode: this electrode made by silver chloride.
3. Internal solution: The silver chloride electrode is dipped in buffer solution of 0.1 mol/L KCL of pH 4 to pH 7.
4. Reference Electrode: It is also the silver chloride electrode use for reference.

5.Junction: It made from ceramic junction also called as diaphragm that allows the contact of sample solution and reference electrolyte. It should not disturb the electric connection between both electrodes.
6. Filling hole: It used for refilling the electrolyte if required.
7. Electrode body: the body is from non-conductive glass or plastic material and may coated by epoxy to prevent glass bulb.

Construction : PH Sensor Toshcon Glass 1 Meter Cable

While acidic solution is rich in H+ ion concentration. Hence pH probe dipped in an acidic solution. Thus The H+ ion moves close to the glass membrane of the sensitive glass bulb (external side of the bulb). Hence Similar reaction occurs inside the bulb. While filled with buffer solution of neutral pH 7. This neutral buffer solution has constant number of Hydrogen ions.

In Breaf :

While the Hydrogen ions concentration across the membrane similar. Hence it called as neutral pH and the pH equal to 7. While If the concentration of hydrogen ion of inside the bulb than outside solution then the given solution is alkaline and the pH is more than 7. Hence pH meter measure the potential difference at both the electrodes and calculate the pH as per the Nernst equation.
