The Series 477AV Handheld Digital Manometer is a precision instrument for measuring pressure, air velocity, and flow in HVAC systems and industrial applications. With ±0.5% full-scale accuracy in optimal conditions, it features built-in velocity/flow calculations to eliminate manual errors and includes field calibration capabilities for reliable performance.
- Multi-Parameter Measurement: Measures pressure (in w.c., psi, kPa), air velocity (fpm, m/s), and flow (cfm, m³/h) with auto-calculations
- High Accuracy: ±0.5% FS at 60-78°F (15.6-25.6°C), ±1.5% FS at 32-104°F (0-40°C)
- Field Calibration: Adjustable zero/span values and damping function for stable readings
- Versatile Display: 0.42" 4-digit LCD with selectable units for 12+ pressure units, 6 velocity units, and 3 flow units
- Portable Design: Lightweight (10.2 oz/289 g) with 9V alkaline battery (150+ hour life)
