TESC Thermoelectric Sample Conditioner System

CANNON product

Automated ASTM D2983 & ASTM D8210 – For Low Temperature Viscosity of Lubricants. 

Category: Tag:


The Thermoelectric Sample Conditioner (TESC) System is the first to automate the entire ASTM D2983 conditioning and testing process including preheating, room temperature stabilization, cooling of the sample to test temperature, and final viscosity testing.

Automation lessens operator hands-on time while integration of the complete conditioning and testing process reduces the temperature fluctuation and result variability associated with other D2983 conditioning options. The system’s low cost and small footprint allow labs to purchase and operate multiple TESC Systems within a relatively small benchtop area. The use of multiple systems enables uninterrupted testing during maintenance of individual units and offers the flexibility of having each unit programmed to a different test temperature.

Thermoelectric Sample Conditioner (TESC) System includes

  • Brookfield DV2T viscometer and support
  • temperature control software
  • #4B2 spindle
  • EZ-Lock spindle coupling
  • pre-loaded test programs on USB memory stick
  • USB to 485 cable
  • test cells (12 pack)
  • 20 mL plastic syringes (5 each)
  • CL 160 viscosity reference standard (500 mL)
  • The unit is pre-calibrated for testing gear oil at –40 °C.

Features & Benefits

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.
