High Temperature Embedment (VW) | Model 4200HT · 4200HT-T
The Model 4200HT and 4200HT-T High Temperature Embedment Strain Gauges are similar to the standard Model 4200. However, the Model 4200HT is designed for short-term use at temperatures up to 200°C and the Model 4200HT-T is designed for long-term use at temperatures up to 220°C. They are particularly useful for measurements in autoclaved spun concrete piles.
