This high-quality device from RS PRO measures airflow and pressure with high accuracy and is a compact and rugged HVAC test and measurement instrument that offers a wide variety of measurement unit options, meaning that this is a functional and versatile tool that can be used across a wide range of pressure measurement applications, whilst offering reliable and accurate readings. This RS PRO manometer has been designed for single-handed operation and offers the most essential features that are necessary for routine maintenance and system troubleshooting applications.

A manometer is a device that is used to measure pressure and the flow rate in the air, in gases or in liquids, depending on the application. These devices are generally compact and portable so that they can be taken to where the readings need to be measured and recorded. Manometers are versatile instruments that can be used across a wide range of industries and applications like:

• HVAC systems maintenance


• Meteorological and weather conditions monitoring


• Gas pressure monitoring in piping systems


• Fluid flow measurements


• Physiological measurements such as blood pressure


• Monitoring compressor systems operations

Barometers or mercury manometers are devices that measure the atmospheric pressure around you. It is a very basic device that comes in a closed-end tube with a vacuum on the other end and measures as the pressure goes up or back down to the absolute pressure point. Manometers also measure atmospheric pressure this, however, in addition to this, manometers have additional features that can measure absolute pressure, differential pressure and gauge pressure and can be used in a wide range of servicing and maintenance applications to ensure that all parts that work using pressure are maintained and fully functional to ensure that downtime is limited.

This manometer measures in 5 different units: psi, inH2O, mmH20, mbar and Pa
