In thermal analysis, differential scanning calorimeters (DSCs) are scientific devices that measure the energy a sample absorbs or releases during heating or cooling.
Researchers, scientists, and engineers in various industries use them to precisely measure and analyze thermal effects like melting, crystallization, and glass transitions.
METTLER TOLEDO DSC instruments, with their sophisticated features and capabilities, offer precise and dependable results that are essential for the creation, production, and quality assurance of a variety of materials.

Benefits of the DSC Instruments
Exceptional Sensitivity
The MMS 1 (MultiSTAR™) sensor's advanced two-layer design, incorporating up to 136 thermocouples, delivers unparalleled sensitivity for DSC. Its outstanding signal-to-noise ratio enables the detection of even the weakest thermal effects, ensuring precise and reliable results.
- Detects weak thermal effects
- Up to 136 Thermocouples
Outstanding Resolution
Achieve unparalleled clarity in material analysis with the MMS 1 sensor. Its remarkably short signal time constant enables ultra-fast enthalpy measurements, allowing for significantly improved resolution of closely spaced thermal transitions.
- Short signal time constant
- Distinguishes closely spaced effects
Flat Baselines
The groundbreaking sensor technology, featuring a revolutionary star-shaped thermocouple arrangement, effectively compensates for temperature gradients. This ensures exceptionally flat baselines and highly reproducible measurement results.
- Enhanced reproducibility
- Accurate measurements
Power Compensation DSC
Customers can select power compensation and heat flux modes using the most recent cutting-edge sensor technology.
Two heaters built into the sensor, one beneath the sample and one beneath the reference, allow the single-furnace power compensation mode. If the sample undergoes an enthalpy change during a measurement, the suitable heater will compensate for the temperature difference between the sample and reference (ΔT) until ΔT = 0.
A heat flow signal with exceptional resolution and separation of close-lying thermal effects results from the extremely accurate measurement of the amount of heat power added to equalize ΔT.

Versatile Modularity
Future-proof DSC analysis with a modular thermal analysis system, ensuring flexibility in configuring the setup according to specific requirements.
People can select what suits them best, ranging from a basic gadget to a fully automated system with a sample robot and time-saving software options. If a customer needs a change, it is simple to implement updates and upgrades whenever they want.
The modularity and upgradeability of cutting-edge instrument solutions will protect user's valuable investment
