美国ARS EPR,ESR专用液氦型低温恒温器 LTR

我司在沈阳某大学成功完成了液氦连续流低温恒温器与Horiba光谱仪的耦合

美国ARS（ADVANCED RESEARCH SYSTEMS）是一家世界级低温系统厂商，创立于1986年，主要产品为低温恒温器和低温探针台，ARS（ADVANCED RESEARCH SYSTEMS）致力于为科研工作者提供1.5-800K低温解决方案。 美国ARS（ADVANCED RESEARCH SYSTEMS）低温恒温器种类繁多，广泛应用于各类光电磁测试，如（显微）光致发光，显微拉曼，显微-FTIR，量子点，磁光克尔效应(MOKE) ，金刚石压砧，热电磁化率测试，荧光，霍尔等等。 产品主要包括液氮储槽型低温恒温器，液氦/液氮连续流型低温恒温器，标准闭循环无液氦低温恒温器，超精细超稳超低振动低温恒温器，顶端装载型闭循环低温恒温器。 各类低温恒温器都可升级为超高真空（UHV）刀口法兰结构，获得10-11torr极限真空。其中液氦/液氮型低温恒温器振动为埃米级别，超精细超稳超低振动低温恒温器振动仅为3-5nm,非常适合对振动要求苛刻的显微拉曼、荧光，激光等常用的显微光谱测试。 顶端装载（Top-loading）结构可实现不停机快速换样，非常适合大批量样品的测试。

Model RO-600(1K) – Ruthenium Oxide RTD – RuO Thermometer from Scientific Instruments

The Model RO-600 Ruthenium Oxide Temperature Sensors are thick film resistors which adhere to are available with calibration down to 20mK or grouped/interchangeable and have a nominal resistance of 1,000? at ambient temperature. The ruthenium oxide temperature sensor offers excellent performance characteristics in magnetic field environments. These sensors exhibit an initial small negative magnetoresistance at temperatures below 250 mK at low fields (less than about 1.5 Tesla). The magnetoresistance then becomes positive at larger fields and increases at lower temperatures. This magnetoresistance is repeatable. For example, a resistance change of 8% induced by an 8 Tesla field at a temperature of 80 mK corresponds to a temperature error of 7 mK.
