The Microprocessor Based Digital Penetrometer provides precise and reproducible consistency measurements of lubricating greases, waxes, bitumens, and semi-solid materials. Featuring motorized penetrator placement, automatic timing, and digital LCD readout, this advanced penetrometer ensures accurate, user-friendly, and ASTM-compliant testing for a wide range of petroleum products.
The Koehler Microprocessor Based Digital Penetrometer is engineered to deliver highly consistent penetration measurements for petroleum products and other semi-solid materials. Using advanced microprocessor control, it automates penetration timing, sample positioning, and data reporting—reducing human error and improving repeatability.
The system performs automatically timed penetrations over a wide programmable interval (0.1–9999.9 seconds) with a default ASTM standard of 5 seconds. A built-in delay option allows for curing or temperature stabilization before testing. Once parameters are set, they are automatically stored in memory for repeat testing. Results are displayed digitally on a large, backlit LCD screen and can be transferred to external systems via RS232 connectivity.
Its motorized penetrator placement and four user-programmable presets ensure accurate positioning of the penetrator tip to the sample surface. Fine adjustments can be made using push-button controls, while a built-in magnifier and illuminator arms provide optimal visibility. For electrically conductive samples, the system automatically detects the surface for perfect tip placement.
The detachable, machined stainless-steel base accommodates a wide range of sample containers and grease worker cups, and can be easily removed for integration with a constant temperature bath. The penetrometer operates via AC power or rechargeable battery, offering versatility for both lab and field use.
