Gel Timer DV3T Instrument

DV3T with Image of Gel Timer Attachment

Brookfield's versatile Rheometer with graphing display shows live gel time data on the instrument screen.  It's the deal choice for R&D when characterizing curing behavior of thermoset materials.  Visual evidence of rapid change in torque is shown by a steep upward climb in the data curve shown on the instrument screen.  Integrated temperature probe provides peak exotherm data, if needed.

Gel Timer DV3T comes with magnetic coupling and glass rod, lab stand with adjustable stop for quickly positioning glass rod at proper immersion depth in test sample and temperature probe.  Test method can be run either manually or using program stored in instrument memory.  Accuracy and reliability of Gel Timer DV3T make this instrument the preferred choice for characterizing gel coats, resins, and potting compounds.  Viscosity data generated during the test is displayed live in a graph on the instrument screen.  This information will prove helpful for complete characterization of material flow behavior.

Packs of 10 glass rods are available; use part number GT-1010.  Spare magnetic couplings can be retrofit to existing DV3T Rheometers; use part number GT-2000.


  • Continuous torque sensing capability
  • Live graphical display of real time viscosity and torque data, gel time, temperature in °C or °F
  • Easy to use:
    • Glass rod fits snugly into the compression-fit coupling
    • Special stop on lab stand controls immersion depth of glass rod
    • Test runs automatically using time-to-torque feature
    • Quick disconnect for rod at conclusion of test
