Description
The MiniAir Junior Macro anemometer set consists of a portable vane anemometer and Macro vane anemometer probe for an air flow range of up to 40ms. The MiniAir Junior is a single channel hand held measuring instrument for air flow measurements using the detachable Macro anemometer probe.The supplied probes is a synthetic plastic construction snap head with an Aluminium vane turbine and handle. The probe generates a pulse each time a vane blade passes the probe handle and the MiniAir Junior display converts this output to a flow velocity.
The MiniAir Junior vane anemometers are available in three different sizes: Micro; Mini; and Macro, with two different flow ranges available for each: 0-20ms; and 0-40m/s and the display may be used with any of the MiniAir Junior Probes. The MiniAir Junior display unit will automatically detect the connected probe during the initial 2 second start up process and adjust the readings to the connected probe. Probes are available with Aluminium vane and handles which are suitable for non-aggressive gases.

Snap-Head Replacement
The snap-head fixing system renders it very simple to fit a new impeller to the flow probe: this saves costly non-productive time and in the event of damage to the snap-head enables you to have the probe back in service in a matter of seconds by simply changing the snap-head.
Any snap head replacement should be of the same original size and flow range.
