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.

Key Features

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

Convenient Operation

  • Magnifier and extra bright LED sample illumination for reliable manual surface detection
  • Jog wheel driven menu (turn and push)
  • Password protection

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
    Rods & rams are suitable for semi-liquid fats, greases and pastes, emulsions, honey, paints, varnishes, potting compounds, ceramic pastes, bread and confectionery
    Test kits for grease, waxes, food, cosmetics, sealing mass, pharmaceuticals, etc. are available.
  • Calibration kit (optional), officially certified for time, distance and temperature check
  • Sensor (optional) for temperature measuring and recording
  • Due to the variety of available test bodies PNR 12 is a modular system and comes without a test body
