Dwyer 2015 MagnehelicDwyer 2015 Magnehelic

Dwyer 2015 Magnehelic Differential Pressure Gauge is a device used to measure the difference in pressure between two points in a system. It is a mechanical gauge that uses a diaphragm and a magnet to indicate the difference in pressure on a scale. This Differential Pressure Gauge has a circular dial face that displays the pressure measurement in inches of the water column (in. WC).
Applications: HVAC systems, clean room environments, and laboratory testing.

Dwyer 477AV-1 Handheld Digital Manometer measures pressure, flow, and velocity along with a number of other convenient features. The built-in air velocity and flow calculations provide accuracy and conserve time and error associated with manual calculations. Also featured on this unit are adjustable zero and span values for calibrating in the field, as well as a damping feature to compensate for the fluctuating readings.

Applications: Airflow monitoring, when used with a Dwyer® pitot tube
• Duct static pressure
• Commercial air balancing
• Building-zone pressure.

Dwyer 8901 Vane Thermo-Anemometer

Dwyer 8901 Vane Thermo-Anemometer is a device designed to measure air velocity, volume, and temperature in industrial applications.
