RS PRO RS-8890 Dual Pressure Manometer

Introducing the RS PRO RS-8890 Dual Pressure Manometer. This high-quality device from RS PRO measures gauge and differential pressure with high accuracy. This dual-purpose pressure monitor has a wide variety of measurement unit options, meaning that this is a great device that can be used across a wide range of pressure measurement applications.

Features and Benefits:

• This RS PRO manometer features 11 selectable units of measurement including inH20, psi, mbar, kPa, inHg and mmHg for flexibility and additional versatility across a wide range of applications
• This unit’s pressure range is at ±2 psi and has a maximum pressure of 10 psi
• The manometer offers a large LCD screen for easy viewing of results and data measurement with a backlight, so it can also be used in low light conditions if required
• The data hold feature allows the user to hold on the data they want to freeze for further analysis
• This unit offers 0.5 second average response time, allowing for quick measurement and readings when time is critical
• The USB port feature is ideal for capturing readings and allowing them to link to a PC using optional software for further investigation and analysis at the convenience of the user
• The device is powered by 9V battery and will shut off after 20 minutes idle time to save the life of the battery, as well as a low battery indicator when the battery requires replacement
• Careful use of this meter will provide years of reliable service


A manometer is a device that is used to measure pressure and 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 devices 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

What is the difference between a manometer and a barometer?

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.
