HDT/Vicat Tester (Standard model) | No.533Heat Deflection/Distortion Tester
- The HDT Tester uses a 2 steps split loading system to ensure simultaneous application of the load on the specimens, applying a consistent fixed stress to the specimens.
- Using their patented design of the stirring and circular flow, Toyoseiki HDT Tester is able to ensure the temperature uniformity of the oil bath.
- Equipped with high precision LVDT, and Pt100 temperature sensors at each station, Toyoseiki’s HDT Tester is able to provide consistent, stable results when measuring the temperature as the limiting distortion is reached.
