For capable calorimetry, with up to two large-volume samples

Designed to measure heat and heat flow on batteries and other large-volume samples.

For capable calorimetry, with up to two large-volume samples

Like the other calorimeters in the Calvet range, the Calvet LV 4C uses 3D sensors consisting of a network of thermocouples surrounding the measuring cells. Larger and made up of more thermocouples than other models, Calvet LV 4C sensors are highly sensitive. Having a greater number of sensors, Calvet LV 4C can also measure two samples simultaneously.

The temperature control of such sensors in practice limits the use of Calvet LV 4C in isothermal mode, but they are capable of ensuring complete detection of heat around the sample. Find out more.

A range of measuring cells enables users to perform diversified measurements, covering studies of heat production, reaction or decomposition of solids and liquids.

Why is it Unique?

HIGHEST HEAT MEASUREMENT ACCURACY

with Calvet 3D sensor based on thermocouples with Joule effect calibration
ISOTHERMAL CONDITIONS

from ambient to 200 °C
LARGE SAMPLE VOLUMES

2 samples simultaneously
Up to 100 mL, or two D-type batteries each
CONVENIENT INTERCHANGEABLE CRUCIBLES AND CELLS

to perform even the most demanding experiments using one instrument :
• high pressure (up to 350 bar) and high vacuum
• pressure resistance, measurement and control
• mixing/stirring experiments
• batteries charge/discharge cycles

Applications

Calvet LV 4C excels particularly in the thermal characterization of batteries, measuring their self-discharge thermal power and the heat released during charge/discharge cycles. These elements are indicators of battery performance, capacity and durability, and are essential for the development of new energy storage technologies. Calvet LV 4C can also be used to analyze the thermal properties of building materials. It is used in biology to study the metabolic processes of small animals, providing valuable data about their interactions with their environment.
