The Koehler microprocessor-based penetrometer is designed to deliver highly accurate and reproducible consistency measurements for petroleum products, lubricating greases, waxes, bitumen, and related materials. Advanced microprocessor control provides a wide range of testing, measurement, and reporting options while simplifying operation through user-friendly programmable presets.
The instrument automatically performs penetration tests using the standard ASTM 5-second interval or any operator-selected interval from 0.1 to 9999.9 seconds. A programmable curing or temperature stabilization delay can also be set before the penetrator is released into the sample. All selected parameters remain stored in memory for repeat testing convenience.
Penetration measurements are available across a range of 0 to 620 in 1/10 mm scale and can be displayed in either 1/10 mm or 1/100 mm increments. For quality control applications, acceptable penetration ranges can be programmed into the system. If the result falls outside the selected limits, the instrument provides an audible alarm and visual alert.
The large LCD display clearly shows countdown timers, test parameters, and final results. Built-in RS232 communication allows direct connection to a printer or computer for easy reporting and data transfer.
To improve test accuracy and repeatability, the penetrometer features four programmable presets for automatic penetrator tip positioning at the sample surface. Fine adjustment controls, manual positioning buttons, a built-in magnifier, and illuminator further simplify operation. For conductive samples, an integrated sensing circuit automatically detects the sample surface.
The detachable base accommodates various sample containers and constant temperature cylinders. The head assembly can also be reversed or mounted directly to a bath housing for flexible use. A built-in rechargeable battery pack supports field testing and provides backup during power interruptions.
