Measure Coatings Right with Uni-T

Got marine gear up in Townsville? Steel frames in Geelong? Or maybe you’re checking the paint job on a used car down in Wollongong? No matter where you are or what you’re working on, getting your coating thickness right is a big deal. If there’s corrosion hiding underneath, one quick reading can be the difference between fixing it early or dealing with a pricey headache later. That’s why so many tradies and inspectors are turning to the Uni-T coating thickness gauge—it takes the guesswork out of the job.

It’s time to ditch the guesswork and measure like a pro.

In this blog, we’ll cover all the good stuff, including:

• Why getting coating thickness right really matters here in Australia

• How the Uni-T UT343D gauge does its job (without the tech headache)

• What to look for when picking a tester that won’t let you down

• Simple ways to keep your gauge accurate and ready to go

• Signs it might be time to upgrade your old gear

• A real story from an Aussie tradie using it on the job

• Common questions answered—plain and simple

Let’s dive in.

Why Coating Thickness Measurement Matters (Especially in Australia)

Australia’s climate puts metal to the test. From salty coastal air in Wollongong to high UV exposure in Queensland, our environment is brutal on paint, powder coatings, and corrosion control.

Here’s where coating measurement makes a difference:

• Marine maintenance in Townsville: Ship hulls, piers, and barges corrode fast without proper protection.
  

  

• Industrial inspections in Geelong: Factories and warehouses rely on powder coatings to protect steel.

• Automotive refinishing in Wollongong: Quality control for body shops and resellers is vital.

"We caught a bad spray job on a fleet car using the Uni-T gauge. Saved us repainting the whole bonnet down the track." —Lee, fleet manager in South Coast NSW

In short: if you deal with paint, metal, or coatings, this tool is your mate.

How the Uni-T Coating Thickness Gauge Works (Made Simple)

Let’s say you’re testing the powder coating on a structural beam. You need a quick reading without damaging the surface. Here’s how the Uni-T UT343D Coating Thickness Gauge makes it easy:

1. Turn it on
Boot up is quick, and the backlit LCD screen makes it readable even in poorly lit areas.

2. Place the probe on the surface
The device uses electromagnetic induction (for ferrous materials) and eddy current (for non-ferrous metals).

3. Get an instant reading
You’ll get coating thickness displayed in microns (µm) or mils, with real-time stats including:

• Average

• Max/Min

• Deviation

4. Save and export
The UT343D allows for data storage and transfer to your PC for reporting.

It works great on:

• Car bodywork

• Structural steel

• Aluminum components

• Powder coatings

• Galvanized surfaces

With automatic substrate detection, even first-timers won’t mess it up.

Aussie Tips & Buyer’s Guide: Choosing the Right Gauge

There’s no shortage of cheap gadgets online, but if you want reliability in harsh Aussie environments, here’s what to keep an eye out for:

1. Dual technology
You want a gauge that works on both ferrous (steel) and non-ferrous (aluminium) materials. The UT343D has both.

2. Data storage and export
If you need to keep inspection records, choose a model that stores readings and can export them via USB.

3. Real-time statistics
Having an average and deviation helps ensure consistent application—ideal for quality control.

4. Durable body
Look for shock-resistant casings and rugged probes that won’t give up on-site.

5. Easy calibration
The UT343D supports zero and foil calibration methods, making it workshop-friendly.

Maintenance Must-Knows for Long-Term Accuracy

Got your gauge? Nice. Here’s how to keep it ticking over for years:

1. Wipe the probe after use
Especially after testing greasy or salty surfaces. Use a soft cloth—no harsh cleaners.

2. Store it in its case
Keep it dry, dust-free, and out of direct sunlight.

3. Calibrate regularly
Use included calibration foils or a known reference plate to ensure it stays accurate.

4. Update firmware (if supported)
Connect via USB for updates that improve performance or fix bugs.

5. Replace batteries with quality ones
Cheap batteries can leak and damage internals. Stick to good brands.

When It’s Time to Upgrade

Still using a manual dial gauge? Here's when to level up:

• It only works on steel (no good for aluminum)

• It doesn't store data or produce reports

• Accuracy is patchy or inconsistent

• You need faster inspections across multiple locations

The UT343D is a solid all-rounder trusted by:

• Marine engineers

• Auto paint specialists

• Building inspectors

• Tradies who need more than just a number

Aussie Client Story: Mick from Townsville

Mick is a surface prep contractor in Townsville, mainly working on marine vessels and port infrastructure. With salt air eating away at steel fast, he uses the Uni-T UT343D to inspect epoxy and primer layers on-site before topcoats go on.

“It’s quick and saves us rework. Found thin patches under the hull that would've rusted out by summer. The lads love how easy it is to use too.”

Don’t leave coating quality to guesswork. If you're working with metal, paint, or powder—especially near the coast—you need a trustworthy gauge.
