Penetrometer: PNR 12
PNR 12 automatically measures the resistance a material provides to being pierced by a specifically shaped test body. The harder the test material, the more pointed and needle-like the test body should be.
The penetrometer is used for consistency and plasticity determination of pasty, creamy, semi-solid or highly viscous samples.
Benefits at a Glance
The patented force sensor plunger (optional) will detect the surface of samples even underneath a layer of water. It starts the standardized test sequence automatically and digitally reports the results on the display.
Suitable samples are bitumen < 160 PU (1 Penetration Unit = 0.1 mm), waxes and other comparable hard materials.
20 programs (16 of which are individually user-definable)
Automatic data conversion (NLGI-class, EN-bitumen value, ¼-cone to solid cone and ½-cone to solid cone)
Limit indicator which gives an alarm when the test value falls outside preset values
Statistical and database functionality (storage of 200 tests, evaluation of Min, Max, Mean)
Data readout with USB stick, conversion to Excel®
Automatic measurements of electrically conductive samples
Magnifier and extra bright LED sample illumination for reliable manual surface detection
Jog wheel driven menu (turn and push)
Customized User Flexibility
Typical PNR 12 accessories:
Needles are suitable for measurements on bitumen, wax, food, cosmetics, etc.
Cones are used for measurements on fats, greases, jellies, creams and similar materials
Perforated disks are primarily used for measuring fluid and highly viscous materials
