Free air manometers Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12765
The Free Air Manometers by Educational Instrument India are reliable laboratory instruments designed for demonstrating and measuring pressure differences in gases and air columns. These manometers are commonly used in physics laboratories, engineering workshops, technical institutes, and educational science labs to help students understand the principles of air pressure, gas pressure, pressure variation, and fluid column measurement.
A free air manometer works on the principle that pressure difference can be measured by observing the height difference of a liquid column, usually water or suitable manometer fluid, inside a transparent tube. This simple yet effective apparatus provides a clear visual demonstration of pressure changes and is ideal for classroom experiments related to fluid mechanics, atmospheric pressure, and gas laws.
Manufactured with durable materials and designed for easy observation, the Free Air Manometer is suitable for repeated educational use. Its transparent tube allows students to clearly see liquid level changes, making it an excellent teaching aid for practical physics demonstrations.

How to Use Free Air Manometers
Place the Free Air Manometer on a stable laboratory table or mount it securely on a stand.
Fill the tube partially with suitable manometer liquid such as colored water.
Connect one end of the manometer tube to the air or gas source to be tested.
Keep the other end open to the atmosphere or connected as per the experiment requirement.
Observe the difference in liquid level between the two arms of the manometer.
Record the height difference and calculate the pressure difference using the appropriate formula.
After use, disconnect the setup carefully and clean the apparatus if required.
Educational Importance
The Free Air Manometer is an important teaching tool for understanding the relationship between pressure and liquid column height. It helps students visually observe how pressure changes affect the movement of liquid inside a tube. This makes abstract physics concepts easier to understand through hands-on practical learning.
Applications
Demonstration of air pressure
Study of gas pressure difference
Fluid mechanics experiments
Verification of pressure measurement principles
Physics laboratory practicals
Engineering and technical education demonstrations
Safety Instructions
