A leading supplier of confined space monitors in Australia

Active Environmental Solutions supply a wide range of confined space monitors, calibration kits, calibration gases and calibration stations to potentially hazardous workplaces across Australia. We are also the authorised agents for RAE Systems by Honeywell here in Australia.

Micro RAE


The MicroRAE can simultaneously monitor up to 4 different gases (such as hydrogen sulfide, carbon monoxide, oxygen, and combustibles or LEL). It is also wireless, ensuring the continuous and instant visibility of safety threats.

GasAlert MicroClip xl

GasAlert MicroClip XL

The MicroClip XL offers a combination of benefits, including: small size, ease of use, reliable operation, and affordable protection. This detector also offers unmatched water protection – up to 45 minutes at a depth of 1.2m.

GasAlert Microclip x3

GasAlert MicroClip X3

The MicroClip X3 offers all the same benefits of the XL model, as well as a new oxygen sensor that extends its overall expected service lifetime to 5 years. This provides you with the confidence it will withstand challenging conditions.



The MultiRAE is the most advanced wireless portable chemical detector on the market. It can simultaneously monitor up to 6 different gases (such as VOCs, toxic and combustible gases, oxygen, and carbon monoxide).

Calibration Kits

Calibration Kits

Having access to calibration kits, regulators, tubing, tools and a full range of accessories can help you to keep your confined space monitors in optimal condition. Pelican cases are also available for ease of storage.

Calibration Gas

Calibration Gas

In order to successfully perform a calibration, known concentrations of test gases are required. We can provide calibration gas to suit all brands of gas detector, as well as provide a full factory calibration when required.


Calibration Station

The AutoRAE 2 is a specially designed calibration station for MultiRAE detectors. It supports a wide variety of gases (including exotic ones) and will take care of all the detector’s requirements: recharging, testing and calibration.
