簡介
Temperature Control Systems
Novocontrol的阻抗分析儀不僅可以做變頻測量，而且可以做變溫條件下的材料介電特性的測量。 此目標的實現得益於Novocontrol自行研究開發的溫度控制系統。
溫度控制擴展了介電與阻抗譜的功能，可以由此確定材料特性的很多重要方面，如介電馳豫、電導、相位分離、相位躍遷、啟動能、玻璃化溫度、混合比率、純度、老化、加工方法等等。

Novocontrol的所有溫度系統都由微處理器控制，操作簡單、安全、全自動操作。 在低頻測量中，整個過程完全電腦控制，幾天內無需人員隨時監控。
系統操作可通過前面板或電腦介面。
以下溫度控制系統可結合BDS介電與阻抗譜儀使用，即成為Novocontrol的Concept系統。 Novotherm-HT系統配備了特製的高溫樣品架，與Novocontrol的低頻分析儀配合使用。

Temperature control extends the performance of dielectric- and impedance spectroscopy.
Many key aspects of material properties such as molecular relaxations, conductivity, phase separation, phase transitions, activation energy, glass temperature, rate of blending, purity, ageing, curing and many others can be determined.
All Novocontrol temperature systems are turn key and microprocessor controlled.
They are designed for easy, safe and full automatic operation enabling computer controlled experiments over several days without supervision as required for low frequency measurements.
All systems are operated either from the front panel or by a GPIB computer interface.
The following temperature control systems are available and can be combined with any BDS dielectric- and impedance spectroscopy systems.
