What is a Ph Meter and and why do we use it

Acids are present everywhere and a PH meter is the lab instruments which answers quickly and conveniently. PH meter is an instruments used to measure acidity or alkalinity of a solution.

What is a Ph meter

A Ph meter is a scientific instruments used to measure the ph value of a given water solution. the ph meter are measures the difference in electrical potential ph electrode and a reference electrode.ph meter is used for testing the ph value.ph meter is also known as a “potentiometric Ph meter”.

How does a ph meter work

Ph meter measuring the voltage and digital display show it as a ph measurement.it calculates this based on the voltage difference; The greater the voltage Between the ph probe (electrode) and the solution being tested, the greater the difference in hydrogen –on activity. The more hydrogen – ion activity that happens, the lower the ph is vice – versa.

Use of PH meter

Ph meter is used for check the acidity of their product, and make accurate ph measurements. Ph meter use to measure hydrogen ion activity in solution ,ph meter are important in chemistry, agronomy,medicine,water treatment, and many other applications.

Types of ph meters

Depending upon the usage  and capability , ph meters can come in various shapes and sizes the common are those :

• Portable ph meters : the portable ph meter are look pen like little rods that you carry about in your pocket, generally the portable ph meter are used for the testing of water because it is very useful and give better measurements and accuracy and its small machine very useful to carry every where.

 

• Benchtop ph meters : bench top meters are mostly sophisticated and strudy devices. You can expect greater accuracy, a higher capacity for data storage and more connectivity option. Benchtop ph meters typically offers more calibration points some bench top ph meter are have system which have to print the result.

 

• Speicialty ph meters : Are expectionally designed presion instruments capable of surviving hazardous chemical and environments.

 

• Holographic ph testers completely different kind of pH sensor, in that they do not touch the liquid at all. Instead, they analyze the liquid by “looking” at it ‒ using colorimetric technologies. These need pH indicators to function, though.

 

So basically ,

The ph meters is very valuable equipment  in  both fields laboratories and industries. This instresting lab instrument is mandatory for most chemical and biological laboratory.
