About This Item
Introducing the Dwyer® 477AV Handheld Digital Manometer - the ultimate pressure measurement device for HVAC technicians and maintenance personnel who demand precision and accuracy in their work. With the upgraded features and user-friendly interface, the 477AV is a must-have tool for anyone in the industry. Its highly accurate differential pressure sensor offers ±0.5% full scale accuracy, allowing you to trust the readings with confidence.
Not only does the 477AV provide pressure measurements, but it also offers flow and velocity calculations, saving you time and effort by eliminating the need for manual calculations. The selectable English and metric units make it adaptable to any measurement system. The built-in air velocity and flow calculations are handy for HVAC technicians performing airflow readings across a duct.
With the ability to save up to 40 readings, you can easily compare and analyze data for efficient troubleshooting and analysis. The digital display features a backlight for easy viewing in darker areas, ensuring that you can work in any environment. The battery conservation feature keeps you informed of low battery voltage, while the automatic shut-off prevents unnecessary drain when not in use.
Calibration is made simple with the field-calibration feature, allowing you to set zero and span values to ensure accurate measurements. The damping feature compensates for fluctuating readings, providing a stable and reliable readout. For added convenience, the 477AV includes an audible and visual alarm to warn of overflows, over pressures, or over velocities.
The menu structure outline on the back of the aluminum casing provides easy navigation, while the comprehensive written instructions ensure a smooth user experience. The package includes a wrist strap and a 9 Volt alkaline battery so you can start using the manometer right away. Trust the Dwyer® 477AV Handheld Digital Manometer for all your pressure measurement needs - it's the tool that professionals rely on for accuracy and performance.
