Both the Brookfield Rotational Viscometer and Rheometer provide rapid, reproducible, high-temperature viscosity measurements aligned with the AASHTO T 201 glass capillary method. Each advanced model characterizes asphalt binder products and develops temperature/viscosity charts to estimate mixing and compaction temperatures in hot-mix design. The units measure at sample temperatures from 9°—260°C (40°—500°F) and are compatible with a variety of spindles. Both systems measure viscosities from 100cP to 40 million cP, are accurate to ±1% and reproducible to ±0.2%.

Powerful programming capabilities include data averaging, results analysis, QC limits, and on screen data comparison, all performed directly on the screen. Built-in RTD probes accurately monitor sample temperature and the auto range feature shows maximum viscosity measured with any spindle/speed combination. The new user interface provides enhanced security with customizable user levels, date/time stamp files, and password access. User instructions with multi-step test protocols can be created with the new PG flash software and uploaded to the Viscometer via included USB flash drive. USB PC interface provides optional computer control and automatic data gathering capability using Rheocalc T software, purchased separately.

A touch screen displays viscosity in cP or mPa/s, temperature in °C or °F, shear rate and shear stress in dynes/cm², percent torque, spindle number and speed, and step program status. Each instrument saves all test data internally, or to a flash drive in Excel format for export, analysis, or graphing.

Units are supplied with a lab stand, RTD temperature probe, spindle guard leg, PG flash software, flash drive, and carrying case. The LPA-52 Programmable Thermosel Set is mandatory in order to comply with AASHTO T 316 and ASTM D4402 requirements.

LP-22 Brookfield DV2T Rotational Viscometer has a 5in (127mm) touch screen and offers data collection capabilities and graphing via a separate software system connected to a PC.

LP-23 Brookfield DV3T Rheometer with a 7in (178mm) touch screen has all the same high-quality capabilities of the DV2T, but real-time graphing of data is built-into the machine, with no need to connect to a PC. This unit also provides rapid analyses for flow index, yield stress, flow curves, leveling and recovery, and can perform yield tests.
