Vapour Pressure Testers

 
 

The vapour pressure testers use the mini method to test solvents, light crude oils and gasoline. These testers have fully evacuated chambers as are required in mini methods. The concept of vapour pressure and how the measurement of vapour pressure proves helpful are mentioned below for your knowledge and reference:

What is vapour pressure?

Vapour Pressure Analyser

Vapour pressure is nothing but the pressure exerted by the vapour above the liquid upon the surface of the liquid. The vapour pressure of any liquid varies non linearly with temperature. Measurement of vapour pressure also gives a clear idea of the evaporation rate of the liquid.

How to measure vapour pressure

There are many different methods and techniques used to measure vapour pressure. The methods vary depending on the material of which vapour pressure is to be measured.

Here we have listed down some of the major methods:

Mini Method

This is a standard test method used for measurement of vapour pressure of petroleum products.

ASVP Method (Air Saturated Vapour Pressure)

This is a method commonly used for non saturated petroleum products and for crude oil.

Reid Method

This is another common method used for measurement of vapour pressure of petroleum products.

AVP Method (Absolute Vapour Pressure)

Vapour Pressure Analyser

This is a method used to measure the vapour pressure of gasoline between 20 to 100 degrees.

The concept of vapour pressure is extremely significant in certain industries. Knowledge of the vapour pressure of certain liquids can prevent many life threatening hazards. The vapour pressure testers and automatic vapour pressure analysers help to know and predict the right temperature at which it is safe to store certain liquids.

We are one of the major dealers of vapour pressure testers in india. We ensure best quality service. Our equipment and testers are certified.
