Particle Pal Plus High Viscosity: Digital Imaging Portable Particle Counter

Portable Oil analysis up to 2,400cSt

Our all new Particle Pal Plus High Viscosity utilises breakthrough digital imaging technology providing unparalleled insight into the size and type of particulate in any oil system up to 2,400cSt. Air bubble elimination and shape recognition gives root cause particle analysis. A stepper motor pump for high viscosity oils completes this package.

Harnessing the power of proven digital imaging technology.

Our High Viscosity version has all the features of the standard Particle Pal Plus but with an enhanced stepper motor pump capable of handling higher viscosity oils. Utilising the advanced S120 digital imaging particle counting technology reports ISO 4406 counts as well as 4, 6, 14, 21, 38, 70 & >100 micron sizing and bubble elimination. 
Digital imaging, combined with advanced algorithms, sorts particles into fatigue wear, cutting wear and sliding wear categories to give root cause analysis. This powerful technology gives unprecedented, on-the-spot insight into the condition of your oil.  Digital imaging technology's results are not affected by oil additive packages that affect laser particle counts (phantom particles).

The image to the right is 4mm x 3mm and shows particulate that the human eye can't see, this image is representative of what the S120 captures. Images of the fuel are not displayed on the Particle Pal Plus screen.

  1. Clear and easy to read ISO code which changes between green, white and red to indicate the oil cleanliness.

  2. High Viscosity stepper motor pump: up to 2,400cSt

  3. Oil cleanliness for each size category details the ISO code, the number of particles per millilitre and the bubbles detected.

  4. Additional reporting methods such as NAS and SAE included.

  5. Additional settings allow control of the pump speed for priming and flushing, datalogging, ISO cleanliness alarm limits and changing the time zone.

  6. Oil cleanliness is trended over time to show how its condition changes.

  7. Particles are analysed and sorted into fatigue wear, cutting wear, sliding wear and fibre identification to give root cause analysis.

  8. Open a full-size QR code which can be scanned from your mobile device to open the last 5 tests as a fully tabular and graphical report on

Online reporting tool

Particle Pal Plus has the ability to generate a QR code, representing the 5 most recent tests. When scanned on a mobile device this will open a fully tabulated and graphical report based on those readings hosted on After viewing the report you can choose to create or log into your user account, then save your reports.

Additional test information can be added to saved reports for future retrieval, as well as optionally displaying your own company name and logo before being shared with third parties such as your own customers.



Digital Imaging Particulate Counter

Capable of broad size determination from 4, 6, 14, 21, 38 & 70 micron counts. Air bubble and water droplet elimination. Shape determination to identify fatigue, sliding or cutting wear as well as fibre identification.

Internal Stepper Motor Pump

We've developed a fully controllable stepper motor-driven pump to deliver exact flow rates for any oil, from 1 to 2,400 cSt. The pump also allows connection to a live system up to 350bar via an optional high pressure adaptor.

Battery Life

Internal rechargeable lithium batteries provide up to ten hours of use.

Particulate analysis 

The Atten2 digital imaging particle counter gives advanced size and shape recognition for any sample.    Counting particulate in fuel and virtually any oil up to 2400cSt, the Atten2 device also eliminates air bubbles, making it ideal for heavy lube and gear oil applications in cold temperatures. Reporting 4, 6, 14, 21, 38 & 70 micron counts as well as categorising any particle greater than 20 microns into Fatigue Wear, Sliding Wear, Cutting Wear and Fibres.
