At GasAlarm Systems, we understand that safety doesn’t stop at the factory floor — it travels with you. That’s why we offer a robust range of portable gas detectors designed to provide personal protection wherever hazardous gases may be present.

Whether you’re working in confined spaces, remote sites, or shifting between job locations, our portable gas detectors deliver real-time gas monitoring for toxic, combustible, and oxygen-deficient atmospheres. From H₂S, CO, NH₃, and Cl₂ to O₂ and VOCs, our units are built to ensure your safety is never compromised.

Our flagship BELL MINI Series features a compact design, high-brightness alarm indicators, loud buzzer, vibration alert, and a crystal-clear 1.6” LCD display. With over 2 years of operation without battery replacement, these units are engineered for durability and reliability in the harshest environments.

Through our BELL Connect™ app, users can easily configure alarm levels, run calibrations, log data, and access real-time readings — all from a smartphone. It’s portable gas detection made smarter.

We’ve been a trusted name in gas detection since 2003. As an Australian-owned and operated business, we’re committed to delivering equipment that not only meets AS/NZS safety standards, but also provides practical value for your on-site personnel.

Whether you’re in mining, laboratories, utilities, or emergency services, our portable detectors are your frontline defense against unseen dangers. And with our in-house servicing and support across NSW, SA, VIC, and QLD, you’ll always have expert help when you need it.
