The Dwyer Instruments 400-5-GAGE is a precision air velocity and pressure gauge designed for professionals in HVAC, industrial plant maintenance, and air balancing. This dual-purpose instrument allows you to measure both air velocity in feet per minute (FPM) and air pressure in inches of water column (in H2O) with a single device, eliminating the need for separate tools and conversion tables.
Key Features & Highlights
- Dual Functionality: Measures air velocity from 400 to 9,000 FPM and air pressure from 0 to 5 in H2O.
- Direct Reading: Red scale for velocity (FPM) and black scale for pressure (in H2O) – no conversion tables required for standard air conditions.
- High Accuracy: Easy-to-read scales ensure precise measurements for critical system balancing and testing.
- Built-in Leveling: Includes leveling adjustment and glass bubble level for accurate readings on any surface.
- Versatile Applications: Ideal for balancing air conditioning systems, measuring pressure drop across filters, and testing fan and blower discharge/inlet pressures.
- Durable Construction: Built to withstand demanding industrial environments.
Applications
The Dwyer 400-5-GAGE is a trusted tool for HVAC contractors, balancing specialists, and industrial plant engineers. It is commonly used to verify airflow in ducts, check filter pressure drops, and ensure proper fan and blower performance. Its portability and ease of use make it an essential instrument for on-site diagnostics and routine maintenance.
