KPH500 Ph Sensor 0-5v Ph Meter Sensor 4-20ma Ph Ec Sensor Probe Meter Controller Tester

Production Introduction

The PH/ORP meter is a precision meter used to detect the pH/oxidation-reduction potential of liquids. It is designed with a microcomputer based on the principle of the primary battery and is simple to operate and easy to maintain. Not affected by color, turbidity, colloidal substances, oxidants and reducing agents, it is suitable for the determination of various media such as clean water, wastewater, industrial water, chemical reagents, etc., and is widely used in agriculture, environmental protection and industry.

 

 

 

The sensor uses a composite electrode, which can eliminate the influence of the inconstant "K" value,

A long-term, stable and accurate measurement of PH is realized. The internal structure of the sensor is shown on the right.

Frequently asked questions

 

 

How to deal with the salt deposit attached to the electrode?

Clean the salt deposits attached to the surface with distilled water.If sediment cannot be washed off the surface, contact customer Service.

 

 

How to choose the right pH buffer?

Calibrating a pH electrode usually requires two buffers of different pH values. First, find out what the sample's pH is

Then select the appropriate buffer to calibrate: a buffer with a lower pH than the sample and a buffer with a higher pH than the sample.

What is pH?What is the principle of measurement?

The pH value of the solution is the negative logarithm of the hydrogen ion activity in the solution, which is expressed as:

 

PH = - lgαH +

 

Because the value of hydrogen ion activity in aqueous solution is often very small, it is not convenient for application, so the concept of pH value is used

As a solution acidity, neutral and alkaline indicators.Moreover, the pH value can indicate the strength of the acidity and alkalinity of the solution.

In this way, it is very convenient to apply, and thus:

Neutral solution: [H+]= [OH-] = 1X10^-7

Moles per liter, pH is minus lg[H+] is equal to 7

Acid solution: [H+] > [OH -], [H +] > 10^-7Mol /L, pH < 7, the lower the pH, the more acidic;

Alkaline solution: [H+]<[OH-], [H +] < 10^-7Mol /L, pH >7, the higher the pH, the more basic it is.

Activity is the effective concentration, that is, the portion of the ion that is free to participate in a given reaction - that is, to reach the surface of the electrode sensitive membrane to connect to it

The part of the ion that's touching it.Because of the interaction between ions in a solution, the activity is usually less than the concentration, and this interaction will also be

Blocking the movement of ions reduces the number of ions reaching the electrode membrane.

 

the measurement of pH electrode is the characteristic of corresponding relation between the output potential of galvanic cell and the pH value of solution.

This correspondence can be epresented by Nernst equation:

E = Eo-2.3 RT/F*pH

E = measure the potential

Eo = standard potential

R = the gas constant

T = absolute temperature (K)

F = Faraday constant

RT/F = 2.3 slope

The Nernst equation is a very important relation in electrochemistry.When measuring pH, Eo(standard potential) and 2.3RT/F(slope) are obtained by electrode calibration. Then the sample is measured to obtain E (measured potential) and the pH value of the sample is calculated by plugging into the equation.
