Automated viscometer TESC Thermoelectric Sample Conditioner System
 
The compact, economical TESC-5133 Low Temperature Viscometer integrates and automates the ASTM D5133 process of conditioning and testing low temperature viscosities of engine lubricants. The TESC 5133 Windows® 10 software application records sample temperature and viscosity throughout the test, then computes the temperature (Gel Index Temperature) at which there is a rapid change in viscosity (Gelation Index).
Common applications include gear oils, automatic transmission fluids, torque and tractor fluids, industrial and automotive hydraulic oils, industrial lubricants, and other fluids where low-temperature viscosity is critical.
