Frequently Asked Questions
What is the Dwyer 477AV-3 digital pressure gauge used for?
The Dwyer 477AV-3 is a handheld digital manometer used for measuring pressure, air flow, and velocity in HVAC systems, pneumatic lines, and industrial gas applications. It calculates volumetric flow and velocity, making it suitable for duct static pressure checks and air flow monitoring in commercial and industrial settings.
What are the specifications of the Dwyer 477AV-3?
The Dwyer 477AV-3 measures 0–500 mbar with ±0.5% FS accuracy (60–78°F). It operates from 0 to 140°F and stores up to 40 readings. Units include in w.c., psi, mbar, Pa, and kPa. It uses a 9 V alkaline battery and has barbed connections for 1/8 or 3/16 inch ID tubing.
Where to buy the Dwyer 477AV-3 in Singapore?
You can source the Dwyer 477AV-3 digital pressure gauge through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this measurement instrument.
How to use the Dwyer 477AV-3 for air flow measurement?
To measure air flow with the Dwyer 477AV-3, connect the barbed fittings to 1/8 or 3/16 inch ID tubing and select the desired flow unit (cfm, m³/h, or m³/s). The gauge calculates volumetric flow and velocity automatically. Use the backlit display for low-light areas and the damping feature to stabilize fluctuating readings.
