The Water Bath ToniCHAT allows the standard-compliant, controlled boiling of binding agent samples (i.e. Le Chatelier moulds) for the determination of the volume stability or rate of risk regarding a subsequent extension of the binding agent (cement) caused by hydration.

The ToniCHAT corresponds exactly to the requirements of the standard EN 196-3 and performs an autonomous and controlled test cycle.

Design / Working Principle

After inserting up to 16 Le Chatelier moulds into the test basket, the basket is inserted into the filled test container with a retaining clip and the test cycle is activated. The ToniCHAT then carries out the test cycle independently until the end.
