MiniAir Junior Anemometer for Air Flow Monitoring.

MiniAir Junior Portable Vane Anemometer with Display

Quick Overview

The MiniAir Junior anemometer is suitable for measuring the velocity of gaseous media. The display provides a reading of flow measurement with 2 selectable intervals, 6 or 22 seconds. Min, max and average readings can be displayed for latest interval. Sets are available with standard micro, mini and macro probes as well as individual displays and probes. Standard probes use a snap head principle for quick and easy replacement without the need for re-calibration. The standard MiniAir Junior is available as complete kit, with probe, display and carry case.

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 either Aluminium or Steel vane and handles. The Aluminium probes are suitable for non-aggressive gases. Steel probes are available with the MiniAir 20 unit and would be more suited for aggressive environments.

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.
