MiniAir Junior Anemometer for Air Flow Monitoring.

MiniAir Junior Display and Probe Sets

Quick Overview

The MiniAir Junior anemometer kits include the MiniAir Junior portable display and a handheld probe. The display automatically detects the connected MiniAir Junior probe attached and adjusts the readings to match. The display can provide a reading of flow measurement with 2 selectable intervals, 6 or 22 seconds. Min, max and average readings can be displayed for latest interval. Kits are available with standard micro, mini and macro Aluminium vane probes. Standard probes use a snap head principle for quick and easy replacement without the need for re-calibration. The Aluminium probes are suitable for non-aggressive gaseous media.

Details

The MiniAir Junior is a portable vane anemometer that is particularly suitable for the heating, air conditioning and ventilation engineer. The MiniAir Junior is a single channel hand held measuring instrument for air flow measurements using a selection of detachable vane anemometers. The vane anemometers come in three different sizes: Micro; Mini; and Macro, with two different flow ranges available for each: 0-20ms; and 0-40m/s.

The individual probes include a synthetic plastic construction snap head with a metal turbine that generates a frequency output each time the metal blade passes the probe handle. The frequency of rotation is virtually proportional to the air-flow velocity and largely independent of pressure, temperature, density and humidity. The MiniAir Junior display converts the rotational frequency into a standard signal and shows the measured value in the display. Probes are available with Aluminium vane and handleswhich 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.
