RESEARCH 3-AXIS ULTRASONIC ANEMOMETER
HS-50
Horizontal head and six analogue inputs, at 50 Hz.
HS-50 pairs the horizontal head with a stainless steel build, six analogue inputs and a built-in inclinometer. The horizontal head minimises flow distortion from the instrument, and the analogue inputs let co-located sensors be logged on the same time base.

WHERE IT SITS
HS-50 in the Research range
Within the Research 3-Axis family the models differ by measurement range, output rate, build and approvals rather than by measurement principle.

BEFORE YOU SPECIFY
Is the HS-50 the correct configuration?
Before specifying, confirm:
- the wind speed range the site actually sees
- the output rate the receiving system needs
- the operating temperature and whether heating is required
- any approval or certification the installation demands
- the mounting arrangement and cable or connector choice
- the interface and output the receiving system expects
If those match, the HS-50 provides that configuration.
