Chemical process safety by design. The RC1mx calorimeter with HFCal option available from METTLER TOLEDO enables development of safe processes at scale.

Understanding the Process

Users can identify the thermodynamic data accurately and rapidly under non-isothermal or isothermal situations.

Heat Flow Calorimetry—Simply Reliable

Strong and resistant against external influence, heat flow calorimetry precisely and accurately quantifies the evolution of heat under process conditions.

Measuring the True Heat of Reaction

Measuring the “Complete” heat of reaction is the foundation for understanding the advance of chemical reactions, their kinetics, as well as hazard potential.

Avoid Incidents at Scale-Up

The secure and very strong RC1mx thermostat can effectively cope with quick and powerful exothermic events. It examines unfamiliar process conditions without any risk to laboratories or operators.

SmartConnect Plug-and-Play Concept

The SmartConnect Technology enables the inclusion of third-party sensors and third-party actors (like dosing pumps) in a plug-and-play fashion by using the adjustment and configuration data stored on a chip in the sensor/actor cable plug.

RC1mx and HFCal: True Heat of Reaction

The entire system includes the RC1mx (30405799) and the HFCal option (30400340). The RC1mx HFCal option allows rapid, accurate, and comprehensive determination of thermodynamic data under all process conditions.
