TESC Thermoelectric Sample Conditioner System

Automated ASTM D2983 & ASTM D8210 - For Low Temperature Viscosity of Lubricants

The compact, economical TESC (thermoelectric sample conditioner) system integrates and automates the entire ASTM D2983 conditioning and testing process for low temperature viscosity of gear oils and ATF, as well as ASTM D8210. Provides an automated alternative to ASTM D2983 sample conditioning and testing. Eliminates sample disruption during preheating, room temperature stabilization, cooling and final viscosity testing. Reduces result variability due to temperature fluctuation. Provides superior precision. Allows for unattended operation.

Common Applications

Gear oils
Automatic transmission fluids

Fully integrated and automated thermal conditioning and testing (−40 °C to +90 °C)

Provides an automated alternative to ASTM D2983 sample conditioning and testing
Eliminates sample disruption during preheating, room temperature stabilization, cooling and final viscosity testing
Reduces result variability due to temperature fluctuation
Provides superior precision
Allows for unattended operation

Pre-developed test programs for common lubricants (gear oil and ATF)

Reduces instrument set-up time
Measures viscosity at multiple speeds automatically

Cost effective, ultra-compact design

Allows installation of multiple TESC Systems in a relatively small benchtop area for redundancy and greater testing versatility
Conserves precious bench space
Dedicated PC is not required for standard instrument operation*

Easy-lift system

Configured for use with the Brookfield® DV2T viscometer and compatible with most Brookfield® models
Simplifies positioning of the viscometer head

Solid-state thermoelectric cooling

Peltier cooling is environmentally friendly and does not require the use of hazardous bath fluids
Enclosed sample chamber mitigates the effects of laboratory air temperature on the sample

Digital recording, printing and exporting of thermal test history and final viscosity data for convenient import into Microsoft® Excel® or other programs

* A PC is required to reprogram the unit for tests other than gear oil at −40° C
