Coating Thickness Paint Gauges (Dry Film)

Positector 6000PCWI is an Australian importer, distributor, sales and service agent of Defelsko's range of coating thickness gauges (paint gauges). We carry a large range in stock and can normally get what you need to you by overnight courier.

Coating thickness gauges are used to test the dry film thickness of most metals, plus concrete, fibreglass, glass, and plastic. The gauges can measure coatings on ferrous substrates, such as steel, and non-ferrous substrates, such as stainless steel and aluminium and non-metals such as concrete, fibreglass, glass, plastic, gyprock and timber.

Our devices measure coatings that include powder coating, galvanising, anodising, plastic coating, and vitreous enamelling, just to name a few.

We sell, support and service a wide range of gauges and probes, capable of measuring coatings from 600micron to 63.5mm.

Your coating thickness gauges need to be verified as accurate when applying coatings, so for ongoing calibration, they are supplied with a working set of calibration films. For a traceable reference, certified films and coated plate standards are available.

PCWI can check the gauges and issue conformance certificates, but the goal is for the customer with certified films or standards to be able to verify their own gauges, saving them time and money. And in using certified films or standards, there’s no real need to send a gauge back to a supplier such as PCWI, unless it is faulty.

 Application Types - For Coating Thickness Gauges


Application types for coating thickness gauges

Your coating/base combination will help with the selection of the right paint gauge, probes & accessories for your application. Take a little time to determine what "Type" your application falls into before speaking with our sales team and we'll be able to determine what you need more quickly.


The Defelsko PosiTector range

PosiTector 200
The PosiTector 200 is ideal when you need to measure coatings on non-metal bases. It's easy to use, accepts a large range of probes and has a large memory which can be uploaded to a computer for later analysis.

PosiTector 6000 Series
The PosiTector 6000 series has models with external/separate probes and models with removable integral probes. The 6000 series paint gauges can measure coatings up to 63.5mm thick on metal and non-metal bases. With a wide variety of probes and accessories, you'll find a combintation to suit your needs. The PosiTector 6000 series are available in a variety of kits complete with probes and accessories to suit typical applications.

PosiTest DFT
The PosiTest DFT has been designed with the Automotive refinishing industry in mind, it's compact and simple to use and comes in ferrous and ferrous/non-ferrous base models.

PosiTector PC
The PosiTector PC measures uncured powder coatings using non-contact ultrasonic technology. 

PosiTector SmartLink
A Smart new way to measure PosiTector SmartLink and free mobile app turns your mobile phone or tablet into a virtual PosiTector paint gauge.


Some things to consider when choosing a coating thickness gauge and probe

On what base material do you need to measure?

  • Ferrous (steel)
  • Non Ferrous (aluminium & stainless steel)
  • Ferrous & non ferrous combined
  • Do you also need to measure on non-metal bases

Do you want a gauge with a Separate probe on a one metre lead or Built-in (integral) probe?

The Separate probe is more popular, as faster to use when checking behind a beam, you can also view the gauge display when the probe is out of sight.

The Integral probe is fine for flat sheeting, steel beams, tanks and larger structures. Positives are not having a probe hanging which may get in the way if you are climbing structures etc.

Probe ranges are:

  • 1500μm (1.5mm)
  • 6mm
  • 13mm
  • 38mm
  • 63.5mm

1500μm probe measures in μm (micron). The other probes measure in mm so if using a 6mm probe to measure, unit reads in mm, ( ie: 100μm displays as .1mm). This can be annoying to someone who wants to read as 100μm etc. If working in less than the 1500μm range most of the time, you are better with a 1500μm probe and purchasing a 6mm or higher range probe just for the thicker coatings.

Do you want a basic (standard) gauge or do you need statistics and reports. The advanced gauges provide very good statistical analysis and offers batching and sub-batching.

Another consideration, if measuring very thin coatings, may be is “accuracy”. The accuracies for the different models are listed on back page of the relevant data sheet.
