What Portable Gas Detectors Do We Supply Serving Melbourne?
Anri Instruments & Controls supplies a broad range of portable gas detection units, from compact single-gas clip-on devices to fully featured multi-gas instruments. Single-gas detectors monitor one specific hazard, such as oxygen deficiency, carbon monoxide (CO), or hydrogen sulphide (H₂S). They are lightweight, simple to operate, and well-suited to sites with a clearly identified singular risk.
Multi-Gas Detectors for Confined Space Entry
Multi-gas units simultaneously monitor for combinations including CO, H₂S, oxygen (O₂), lower explosive limit (LEL) gases, carbon dioxide (CO₂), nitrogen dioxide (NO₂), ammonia (NH₃), and volatile organic compounds (VOCs). These are the preferred choice for confined space entry work, where multiple atmospheric hazards may be present at once.
Specialised Portable Analysers and Hazardous Area Instruments
Anri Instruments & Controls also supplies specialised portable analysers for landfill and biogas management, food and pharmaceutical modified-atmosphere packaging, and compressed air quality monitoring. The range includes IECEx-approved instruments rated for hazardous classified zones, an important consideration for facilities in Dandenong South and Campbellfield where flammable or explosive atmospheres are a recognised risk.

Serving Melbourne's Key Industries and Locations
Portable gas detectors serve a wide range of Melbourne workplaces, including the following:
▸ Manufacturing plants in Dandenong, Campbellfield, and Knoxfield, where VOCs and combustible gases may be present during production.
▸ Wastewater and water treatment facilities requiring H₂S monitoring across Greater Melbourne's sewer networks and treatment ponds.
▸ Construction and civil projects in the CBD, Port Melbourne, and south-eastern growth corridors, where confined space entry is routine.
▸ Laboratories and research facilities requiring precision portable analysers for CO₂, O₂, and speciality gas monitoring.
▸ Food, brewing, and cold storage operations where CO₂ and refrigerant leaks can pose serious risks to staff.
▸ Biogas and landfill sites in outer Melbourne and regional Victoria, where methane (CH₄) and CO₂ monitoring is a compliance necessity.

Do Portable Detectors Need Calibration?
Yes. Under AS/NZS 2865:2009 and harmonised Work Health and Safety (WHS) regulations, atmospheric testing equipment used for confined space entry must be correctly calibrated. Safe Work Australia's Code of Practice reinforces that atmospheric testing must be carried out with a suitably calibrated instrument operated by a competent person.

Frequently Asked Questions About Portable Gas Detectors in Melbourne
What Is the Difference Between a Single-Gas and a Multi-Gas Portable Detector?
A single-gas detector monitors one hazard; a multi-gas unit detects several at once. AS/NZS 2865 confined space entry generally requires multi-gas units.
Which Gases Can Portable Detectors Monitor in Industrial Settings?
Common targets include CO, H₂S, O₂, LEL gases such as CH₄ and propane, CO₂, NO₂, NH₃, VOCs, and refrigerants.
Can I Buy Portable Gas Detectors Through Anri Instruments & Controls?
Yes. Anri Instruments & Controls supplies portable gas detectors for purchase, tailored to your industry and gas hazards. Contact the team to request a quote.
How Often Should a Portable Gas Detector Be Serviced?
Annually at minimum, with bump testing before each day of use. Anri Instruments & Controls’ gas calibration and testing services can set a compliant schedule.
Does Anri Instruments & Controls Serve Businesses Outside of Inner Melbourne?
Yes. Anri Instruments & Controls serves regional Victoria, including Knox, Dandenong, and Yarra Ranges. Contact to confirm coverage for your location.
