Test Equipment by Dwyer Instruments 聽

Description

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
  LCD.
• 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.
