Most of the calorimeters and thermal analyzers available on the market these days work by the calvet principle. Such a measurement method (and thus calorimeters and thermal analyzers operated by this principle) has several advantages over the other thermal analysis methods that are in use today.
Fist of all, calvet calorimeters and thermal analyzers provide the whole heat-flow measurement. As long as the sample during the measurement procedure is totally begirded by the thermodetector it (thermodetector) measures the full heat-flow around the sample.
The second advantage of calvet calorimeters and thermal analyzers is that they provide more precise calibration than other methods. This means that results you get with calvet calorimeters and thermal analyzers are also more precise. Usually calvet calorimeters and thermal analyzers have bigger volume of measuring cell which allows performing different reactions between two samples (solid state - gas, solid state - liquid, liquid - liquid and liquid - gas) right in the measuring zone of the chamber of calorimeter or thermal analyzer.
And another great advantage is that in calvet calorimeters and thermal analyzers much bigger samples can be analyzed. Many firms these days produce different sorts of thermal analysis device.
In the market of devices for thermal measurements Setaram Instruments is one of the leading companies. The range of available setaram products is huge. They have calorimeters and thermal analyzers to perform all sorts of DTA (Differential Thermal Analysis) including high volume DTA (with sample volumes upto 500 micro liters) and DTA with special detectors that can withstand aggressive environments. Setaram is the only producer that has a range of calorimeters and thermal analyzers to perform all sorts of DSC (Differential Scanning Calorimetry).
You can easily find high-temperature DSC analyzers and highly sensitive DSC analyzers as well (setaram micro DSC family allows to measure thermal effects that can not be detected by other DSC methods). Highly sensitive measurements can also be performed with calvet DSC analyzers. Along with different DSC models Setaram Instruments also offers different unique implements like high pressure crucibles, crucibles of bigger volume, joule-effect calibration and many others.
All the Setaram products are very stable and have high precision and sensitivity thanks to their high quality components. For example, all the Setaram balances are built by zero level principle. That allows performing both simple and symmetrical TGA (Thermo Gravimetric Analysis). Setaram Instruments product family also includes several analyzers for TMA (Thermo Mechanical Analysis). These TGA analyzers can work in a big temperature rage (from -150 degrees Celsius to 2400 degrees Celsius). No matter what sort of analysis you need to perform you will be satisfied with the highest quality and precision of Setaram Instruments products.
