Product Introduction
The Dwyer Series 477AV Handheld Digital Manometer is a portable precision instrument designed for on-site measurement of pressure, air velocity, and flow in HVAC, industrial, and environmental applications. With built-in calculation functions and field-calibration capabilities, it eliminates manual errors and streamlines testing processes.
Product Features
Triple Measurement Modes:
Pressure: in. w.c., psi, kPa, mbar, etc.
Velocity: fpm, m/s, mph, knots.
Flow: cfm, m³/h, m³/s.
High Accuracy:
±0.5% FS at 15.6–25.6°C (60–78°F); ±1.5% FS in extended temperatures.
Field Calibration:
Adjustable zero/span values and damping function for fluctuating readings.
Portable Design:
9V battery operation (user-replaceable), 10.2 oz (289 g) weight for handheld use.
NIST Calibration:
Optional traceable certification for critical applications.
