LP-23 Brookfield Rheometers, DV3T measure viscosity and yield stress at sample temperatures from 9°—260°C (40°—500°F). Viscosities are measured from 100cP to 40 million cP. Measurements closely align with the AASHTO T 201 glass capillary method of testing kinematic viscosity. The DV3T provides data analysis for flow index, yield stress, flow curves, leveling, recovery, and single-point viscosity value. Accuracy of the Brookfield DV3T Viscometer models is to ±1% of range. Reproducibility is to ±0.2%. Compatible with a range of spindles.
These units are equipped with a 7in (178mm) full-color touch-screen display and feature real-time graphing of data. Programming of test parameters can be performed directly on the screen. Data can also be transferred to a PC or sent to a printer. Built-in math models allow for rapid data analysis for flow index, yield stress, flow curves, leveling, and recovery . The display supports multiple languages. Viscosity is shown in cP or mPa, temperature in °C or °F, and shear rate and shear stress in dynes/cm².
It also displays percent torque, speed/spindle, step program status and math model calculations.
Single point viscosity can be determined in QC laboratory applications, as well as comprehensive flow behaviors for research and development purposes.
Security functions include password and customizable access, date and time stamp file, and portable log-in settings. The devices offer math modeling, customizable speed/spindle lists, and timed or yield tests. Built-in capabilities include programmable alarms and QC limits, RTD temperature probe, USB interface and more. Custom test programs can be created and downloaded using the included PG Flash software. Internal data storage capacity is 150MB.
The rheometers come with a lab stand, carrying case, screen protector, spindle guard leg, PG Flash software, and a flash drive. LPA-62 RheocalcT Software, sold separately, is available for enhanced performance and data collection on a computer. Test data is easily transferred using the included flash drive.
