The NHP200 Series 2, is the flagship Holmen pellet durability tester used worldwide for calculating the Pellet Durability Index (PDI) of feed and wood pellets by simulating the pellet transportation environment from mill to trough.

Once a sample of pellets is loaded into the machine it removes any fines, weighs the sample, tests the pellets by agitating them with air at a fixed 70mBar pressure, weighs the remaining sample and calculates the PDI.

This automatic solution removes the chance of human error, providing an accurate and reliable test method. The reduction in human input also allows other tasks to be completed while a test is done, ideal in a busy laboratory or where a wide number of staff carry out the testing.

The average test lasts only 4 minutes and the test time is automatically set according to the pellet diameter entered. Suitable for pellets 3mm-12mm diameter.
