TMA Dual pushrod dilatometers can perform 2 absolute measurements or 1 differential measurement between 2 samples. Dual pushrod dilatometers are available in vertical models only.
Instrument calibration insures the best test results of material expansion or shrinkage.
Test conditions must be duplicated during the calibration procedure including heating rate, sample holder material, furnace, gas flow, and atmosphere conditions. C are available as table- top units. All vertical dual pushrod dilatometers feature a motor driven furnace lift. All dilatometers have auto-zeroing and automatic sample length measurement included. The vertical models eliminate any friction between the sample and the measuring system.
