Test Equipment by Dwyer Instruments
Dwyer extensive range of test equipment is functional and
specified to many industries. The range includes:
- The SERIES SAH SMART Air Hood Balancing Instrument is the
most accurate and easy to operate air flow hood on the market. By using the
included hood stand and wireless communications to the handheld, a single
operator can balance a branch in less time than traditional balancing teams. Besides
being lighter than most traditional capture hoods, the ergonomic design makes
the Series SAH easy to manoeuvre, with less physical stress. The rugged
polypropylene base hood features patented Quad Flow Design Technology for
controlling air flow and minimizing back pressure, which yields superior
measurement accuracy. The Wi-Fi direct communication gives reliable
communication with a distance of up to 200 yards (183 m) between the hood and
the handheld test instrument. The SMART Air Hood Balancing Instrument includes
the PredictAir™ Application Software which reduces the number of steps in the
air flow balancing process using Predictive Balancing Express Balance mode.
Predictive Balancing is a method of predicting the optimal flow set point for
each register and the order in which they should be adjusted.
- The SERIES 477AV Handheld Digital Manometer is
now available with pressure, flow, and velocity measurements 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 of readings.
- The SERIES 490A Hydronic Differential Pressure Manometers are
versatile, handheld, battery operated manometers available in several basic
ranges for positive or positive differential pressure measurement and can
tolerate most liquid media compatible with 316LSS. A new feature added to the
Series 490A is a field adjustable damping, which allows the user to choose the
level of display averaging rate corresponding to the fluctuation level common
in many applications.
- The MODEL 485B Thermo-Hygrometer is a versatile,
compact, handheld instrument for measuring percentage of relative humidity and
temperature in F or C. Dew point and wet bulb temperatures are derived from
the relative humidity and temperature measurements and are displayed on the
- The MODEL 471B Thermo-Anemometer Test Instrument is
a versatile dual function unit that quickly and easily measures air velocity or
volumetric flow as well as air temperature in imperial or metric units. A
stainless steel probe is included, which has a comfortable hand grip and etched
insertion depth marks. The extruded aluminum housing fully protects
electronics, yet is lightweight and comfortable to hold.
