Dwyer 1227 Dual Range Flex Tube U-Inclined Manometer
The Dwyer Model 1227 is a versatile, dual-range flex tube manometer engineered for accurate low-pressure air measurement in HVAC, laboratory, and industrial applications. Its unique design allows it to be used in two orientations — vertical or inclined — giving technicians the flexibility to select the measurement range best suited to the task at hand.
Dual-Range Measurement
- As Vertical (U-tube configuration): Reads 0–16″ Water Column with 1″ major divisions and 0.2″ minor divisions for broad-range pressure checks
- As Inclined: Features a 17″ long scale reading 0.20–0–2.6″ Water Column with 0.02″ minor divisions for high-resolution, low-pressure differential measurements
Key Features
- Flexible tube construction for durability and ease of use in the field
- Dual-range capability eliminates the need for multiple gauges
- Inclined scale provides enhanced readability and precision at low differential pressures
- 17″ inclined scale length for easy, accurate reading
- Compact, portable design suitable for duct pressure, filter resistance, and fan performance testing
- Manufactured by Dwyer Instruments, a trusted name in pressure measurement
