MiniAir JuniorEx Portable Vane Anemometer with Hazardous Area Display

3-4 Weeks

Quick Overview

The MiniAir Junior Ex Approved 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.

Details

The MiniAir Junior Ex is a portable vane anemometer designed with an explosion protected housing for use in hazardous area applications. 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, whilst the Steel probes are more suited for more aggressive environments and more durable.

Features

  • Suitable for use with all MiniAir JuniorEx flow sensors.
  • 4 Digit LCD display
  • Instantaneous value measurements
  • Minimum, Maximum and Averare values continuously selectable
  • 2 Average value measurement intervals: Fast = 6 Secs, Slow = 22 Secs.
  • Easy operation by key pad
  • Snap head vanes for easy measuring vane replacement, existing calibration retained.

The internal battery is replaceable and the unit should be removed from the hazardous area to a safe area when the battery is being replaced. Any replacement battery needs to be one that is approved in the MiniAir Junior EX Certification to retain the ATEX certification. The use of any other battery would invalidate the certification of the unit and it should not be retaken back into the Hazardous Area with an incorrect battery. The battery compartment has to be resealed and secured with the special screw after changing battery before returning it to any Hazardous Area. A special screwdriver is supplied with each new display to allow the battery compartment to be opened.

Snap-Head ReplacementSnap Head Principle

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.
