PVS1™ – Rapid Paint Volume Solids Measurement

PVS1 is the only paint volume solids (PVS) instrument in the world. It delivers accurate, repeatable PVS results in minutes and requires minimal operator training.

Measure paint batch to batch consistency, determine the true cost of paint on an applied area basis, compare paint suppliers, convert wet film thickness to dry, and work out how much paint is needed for every order. The uses for, and value of knowing PVS% are broader than most operators imagine.

Or, if you are a paint manufacturer PVS1 delivers the world’s best practice QC before your paint production batch is completed. Deliver a more consistent product to your client, deliver better quality information to your client, and create a point of differentiation against your competitors.

‘Accurately predict dry film build using measured paint volume solids data and hit your target film build from the commencement of production – PVS1 works hand in hand with WFM1’

The Wolf Paint Volume Solids Instrument is a compact and robust portable instrument designed for operation in industrial and laboratory environments.

Deliverables and Features

• Delivers a simplified approach to paint volume solids measurement
• No skilled technicians and no complex lab procedures required
• The automated test cycle includes full paint cure with analysis in under 5 minutes – that’s a big improvement on the less accurate 2 hour lab test for PVS
• Delivers accurate paint volume solids (PVS) results to +/- 0.6%
• Mimics paint line operations on a small scale hence results relate directly to coil coating lines or industrial paint finishing processes
• Determine how much paint is needed for a production order
• Measure the batch to batch consistency of paints
• Measure long term trends in paint quality across all suppliers
• Annual paint costs come to many millions of dollars. PVS1 provides the first true instrument to measure the quality and consistency of this most precious ingredient in your operation.



The Wolf Innovation suite of products deliver fabulous benefits but with so many choices theypose the question of what to install. So how do you decide what components logically fit together to deliver the best business outcome for your production line. Here you will find the logical combinations for complete quality assurance of all coating layers. The instrument packages are designed to deliver the best outcomes and the best business case to suit your needs.


One of the great things about this system is that you don’t need to buy it all right from the start.

There are two logical alternative starting points to build up CCS1. The choice between these is simply based on available capital. If its low then start with DFM-Ultra to get immediate paint savings and guarantee quality. In fact DFM-Ultra is so cost effective, every paint line should have this – regardless. A great advantage of DFM-Ultra is that it can easily be upgraded to a full DFM1 at any time in the future. Having started with DFM-Ultra the next logical step is to add WFM1 and PVS1. This addition adds the ability to set up the coater before production commences. WFM1 and DFM-Ultra talk during production and compare notes. DFM-Ultra will fine tune WFM1 for perfect monitoring of every coil from the very first metre.

The other great starting point is WFM1 with PVS1. Eliminate test strips, eliminate wet film wheel track marks, save paint, save steel and improve your lines yield. If you do test strips now the savings are likely to be well above $1,000,000 every year. Use your first month’s savings to add in DFM-Ultra.

That combination – WFM1/PVS1/DFM-Ultra is the foundation of CCS1. It’s the perfect basis from which to introduce closed loop control. It is a wonderfully automated easy to use system. Of course the operator will still have to do paint volume solids testing which takes a minute of his or her time at every paint change.


Now you’ve got your topcoat fully in control. That’s where the biggest savings are. You can now focus on primers and backers.

I personally like the idea of adding a Phaeton lab thickness instrument at this stage of the CCS1 build up. It’s unique in that in just 2 seconds you get hundreds of measurements from edge to edge – a full profile of thickness results providing unprecedented information on the condition of your coater roll and the coater set-up. Phaeton should be located just near the exit shear of the paint line. Cut the sample and measure the profile in seconds. Ideally the monitor showing the sample results is located at the coater room with a second monitor in the quality control lab. Measure the topside, then flip over the sample and measure the bottom side. Generate a sample of primed strip at the leading edge of each coil so that you can measure primer thickness quickly and efficiently, and again, on both sides of the strip.

So when should you add the Phaeton – about 2 months after installing WFM1/PVS1. Just use the savings in hand – it won’t cost anything in real terms.
