Brookfield Viscometer

LP-22 Brookfield Viscometers, DV2T provides rapid measurements of medium viscosity samples. When testing in accordance to ASTM D4402 and AASHTO T316 standards, the LP-22 measurements can be used to determine mixing and compaction temperatures of asphalt and estimate binder flow, mix, and performance characteristics in varying climatic conditions. A rotating spindle is placed in asphalt binder heated to precisely-controlled temperatures using the LPA-52 Thermosel Set. The spindle torque and speed are then used to measure the binder’s apparent viscosity.

The LP-22 features a 5-inch (145mm) color display with multiple-language support. Programming capabilities include timed tests, data averaging, quality control limits/alarms, customized speed/spindle lists, step program status, and data comparison. Auto range feature shows maximum viscosity measured with any spindle/speed combination. Multi-step test protocols can be created and uploaded to the LP-22 via USB. Security features include password access, date and time stamp file, and customizable user access. Test data is stored internally, with a data capacity of 150MB. LPA-62 RheocalcT Software, available separately, increases efficiency with automated data collection and analysis. Results are transferred to the flash drive for upload to the user’s computer.
