Brookfield Viscometer

LP-22 Brookfield Viscometers, DV2T automate viscosity testing. Measurements determine the asphalt binder’s temperature/viscosity relationship and estimate mixing and compaction temperatures in hot-mix design. Viscosity measurements are rapid and closely align with the AASHTO T 201 glass capillary method. The unit measures at sample temperatures from 9°—260°C (40°—500°F) and is compatible with a variety of spindles. Viscosities are measured from 100cP to 40 million cP. The LP-22 Brookfield Viscometer models are accurate to ±1% and reproducible to ±0.2%.

The Brookfield DV2T is equipped with a 5.7in (145mm) touch-screen full color display with user interface and enhanced controls. The display supports multiple languages. Viscosity is shown in cP or mPa/s, temperature in °C or °F, and shear rate and shear stress in dynes/cm². It also indicates percent torque, speed/spindle, and step program status. Enhanced security features include password access, date and time stamp file, and customizable user access. Other features include customized speed, data averaging, programmable limits and alarms, timed tests, USB interface and more. Test data is stored internally, with a data capacity of 150MB.

The viscometer includes an RTD temperature probe, and spindle guard leg. It also comes with a screen protector, stand and carrying case. PG Flash program generator software for developing multi-step test protocols and a USB flash drive are also included. 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.
