TQC Sheen Fibro PGX+ Pocket Goniometer

Understand the surface properties of everything from windshields and metal cylinders to solar panels with our industry-leading pocket goniometers.


Brought to you by TQC Sheen, our specialist paint testing brand, the Pocket Goniometer PGX+ gives you exceptional, video-based quality control capability.

Pocket goniometer perfection

Our highly accurate goniometer measures the contact angle (both dynamic and static) of liquid droplets on a wide range of materials. Taking some 80 pictures per second, it makes surface tension and surface free energy (SFE) inspection quick and easy.

First the PGX+ goniometer makes a drop in µl according to the size you set. The drop is automatically released and the high-tech camera gets to work! Typically you’ll want to use deionized water for your tests, but you can also work with other liquids.

Expert goniometer testing analysis

Your test data is instantly transferred to your computer,  connected to our custom-designed software. This powerful link-up gives you an easy overview of the possible tests. Pictures and results are stored and analyzed while the direct feedback helps you to make quick adjustments to improve the results.

Full control goniometer testing

The Fibro PGX+ digital goniometer is the ideal instrument to perform dynamic tests like absorption tests. During a test, the apparatus is connected to the computer. Our software provides an accessible overview of the optional tests, giving you full control. The goniometer’s adjustable parameters include droplet size, method of deposit, start delay and sample rate.

No prep goniometer testing

The Fibro PGX+ Pocket Goniometer creates a mini test environment which you can place samples directly onto. So you don’t have to waste valuable time preparing individual samples.

Surface tension goniometer measure

The shape of the pendant droplet is registered by the camera alongside information on the intermolecular forces.

Perfect goniometer testing – as standard

Our goniometer conforms to all major international standards, including ASTM D724 and ASTM D5946.

Pocket goniometer dosing unit

As an optional extra, check out the goniometer dosing unit we make. An add-on pumping device that delivers consistent liquid droplets from a disposable one ml syringe, enhancing the accuracy of droplet delivery even further.

Related goniometer products

Across the IP portfolio we make a wide range of goniometer related products. For example, there’s the TQC Sheen Fibro PGX+ Pocket Goniometer PG1000 and we also make the TQC Sheen Fibro PG Dosing Unit.
