Koehler - Penetrometer - Digital Penetrometer

Penetration tests are performed on petroleum products to determine consistency and shear stability (lubricating greases) for design, quality control and identification purposes. A standard cone or needle is released from a penetrometer and allowed to drop freely into the sample for 5 seconds (or a different specified interval) at constant temperature. The depth of penetration of the cone or needle into the sample is measured in tenths of a millimeter by the penetrometer.

Technical Specifications

  • Tests the consistency of lubricating greases, petroleum waxes, bitumens, pastes, creams and other solid to semi-solid products
  • Automatically timed operator programmable penetration measurements
  • Motorized placement of penetrator on sample surface
  • Large LCD to display all functions
  • RS232 port for data transfer
  • Full measurement range of 0-620 in 1⁄10mm scale or 1⁄100mm scale
  • Rechargeable battery or AC operation
  • Large, removable base accommodates grease worker cups and other
  • ASTM and non-standard sample containers
  • Complete selection of penetrometer cones, needles and accessories for petroleum products testing and for a wide range of other applications
  • Conforms to all ASTM, IP, ISO 9001 and related specifications for penetrometers
