If you’re an HVAC tech in Australia, chances are you’ve heard the name Fieldpiece floating around the worksite or popping up in group chats. These analysers are showing up everywhere—from rooftops in Sydney to garages in Brisbane and dusty vans in rural WA.
But what’s all the fuss about? Are they actually worth your hard-earned coin?
In this review, we’re cutting through the marketing and sharing real experiences from Aussie HVAC professionals. Whether you're a solo tradie in Adelaide or running a team in Melbourne, this guide gives you the info you need—minus the tech jargon.
In this article, you’ll learn:
Why Fieldpiece system analysers are taking over Aussie job sites
Key differences between the CAT45 and CAT85
Tips from experienced HVAC tradies around Australia
A real customer story from Bendigo
FAQs about compatibility, durability, and calibration
From humid Darwin days to freezing Ballarat mornings, Aussie HVAC jobs are brutal. Many imported tools just can’t handle our heat, moisture, and dust. That’s where Fieldpiece shines—with rugged cases, water separation pumps, and Bluetooth controls that work in 40°C heat without chucking a tantrum.
A combustion analyser isn’t just a nice-to-have—it’s a life-saving tool. Detecting carbon monoxide early protects your clients, your licence, and your reputation. That’s why tradies trust the CAT45 and CAT85—they deliver fast, accurate readings on every job.
From gasfitters on the Gold Coast to sparkies in Tassie, Fieldpiece has become the go-to. And it’s not just big HVAC companies—sole traders love the reliability and sensor life too.
In a nutshell, they test combustion appliances like gas heaters and boilers to check how cleanly they’re burning fuel.

This one came from a tech in Newcastle: “I’ve gone through three cheap analysers. The CAT85’s lasted two summers already.” You really do get what you pay for—cheap tools can cost you more in the long run when they break or give dodgy readings.
The Job Link app integration is a game-changer. You can save time writing reports, and even better—send the readings straight to a client if you’re quoting. It also makes you look more professional when your gear isn’t held together with duct tape.
Not every Fieldpiece analyser sold online is set up for Australian gas standards. That’s why shopping from an Aussie supplier like HVAC Trade Supply matters—you know the gear’s calibrated for our systems.
Fieldpiece’s SensorVault tech means longer sensor life and cheaper servicing. A tech in Darwin reckons his sensors have outlasted three of his old units. That’s a win.
Chris has worked solo in regional VIC for 12 years. On a scorcher—42°C—his old analyser died mid-carbon monoxide test.
“I had to drive 90 minutes just to grab a backup. After that, I got the CAT85. It hasn’t failed once—even with back-to-back installs in peak summer.”
He now recommends it to every apprentice he trains. Safety first.
