CALVET PRO
CALVET calorimeters have their 3D sensors in common. They are made of a thermocouples’ network surrounding the measurement cells. Basically, no heat is lost during measurements. CALVET PRO is designed to test mg scale samples over a large temperature range, with many interchangeable cells and crucible options.
With CALVET PRO you can characterize most materials for Energy and Environment. It includes more particularly catalysts and sorbents. Its High-Pressure options are also used to test hydrogen storage materials, energetic materials, and for Process safety evaluations. Its excellent Cp measurement accuracy is beneficial for most material characterization.
Product Information
Highest heat measurement accuracy, calvet 3D sensor based on thermocouples with joule effect calibration.
Highest mass variation accuracy with its optional Hang-down Symmetrical Beam Balance.
Sub-ambient to high temperature operations, from -120 to 830 °C.
Isothermal or temperature scanning modes for increased flexibility and replication of real life conditions.
Convenient interchangeable crucibles and cells to perform even the most demanding experiments using one instrument: high pressure (up to 500 bar) and high vacuum, pressure resistance, measurement or control and packed bed reactor experiments.
