Down
Features High Speed Quenching Dilatometer (L78/RITA) As per ASTM A 1033 -04 Induction or light furnace Expansion measurement with LVDT (conventional) or Laser (highest resolution) Heating and cooling rate 100K/sec (standard configuration) controlled heating and cooling rates Temperature -150 up to 1600°C (different models) Maximum vacuum 10E-5mbar sample heats while the protection tube remains cool Ultra fast data acquisition 1000 samples / second Creation of CHT, TTT and CCT diagrams with Software Horizontal or vertical mode of operation
Main advantaged of the L78 RITA Quenching Dilatometer system: Possibility to measure under vacuum, inert, oxidized, reduced atmospheres up to 1600°C. (Not possible with resistance heating furnace). Measurements from -150 up to 1600°C in one run (no need of exchanging furnaces to cover the temperature range) Very fast heat up and cool down speed Expansion of any type of sample can be measured (susceptor) Possibility to measure either with LVDT expansion principle, or with laser expansion measurement principle This special Quenching dilatometer can be used for the determination of continuous cooling / heat up CHT, CCT and isotherm TTT- diagrams.
