The Series 477AV Handheld Digital Manometer is a versatile measuring instrument designed to accurately measure pressure, air velocity, and flow in various applications. With ±0.5% full-scale accuracy (at 60-78°F/15.6-25.6°C), it eliminates manual calculation errors by integrating built-in velocity and flow algorithms. The device features field-calibratable zero/span adjustments and a damping function to stabilize fluctuating readings, making it ideal for HVAC diagnostics, ductwork testing, and industrial airflow management.

Product Features
Multi-Parameter Measurement
  • Measures pressure (in w.c., psi, kPa, etc.), air velocity (fpm, m/s), and flow (cfm, m³/h)
  • Auto-calculates velocity/flow from pressure inputs, reducing field errors
Accuracy & Stability
  • ±0.5% FS accuracy in optimal temperatures (60-78°F), ±1.5% in extended ranges (32-104°F)
  • ±0.1% FS hysteresis for consistent readings across pressure cycles
Field Calibration
  • Adjustable zero/span values for on-site calibration without external tools
  • Damping feature to smooth out transient pressure fluctuations
Display & Units
  • 0.42" 4-digit LCD with selectable units for pressure, velocity, and flow
  • Supports 12+ pressure units (e.g., in Hg, mbar), 6 velocity units, and 3 flow units
Portability & Power
  • Lightweight design (10.2 oz/289 g) with 9V alkaline battery (user-replaceable)
  • Low-power mode for extended field use
