用于 Peltier 板的 上板

Peltier 上板 在进行室温外的测试时,温控相应迅速,精确度无与伦比。 说明特点技术应用Video 帕尔贴上板(Upper Peltier Plate, UPP) UPP 是一款针对室温外测试的重要的温控系统,温度响应迅速。当温度控制系统仅对样品的一侧进行控制时,甚至仅是在40℃下进行测试,温度测试偏差也可以上升到40%,并且测试偏差随着测试温度偏离室温越多而不断增大。将 UPP 与 Peltier 下板结合使用,可在 -40°C 至 200°C 范围内进行均匀而精确的温度控制,从而消除粘度、屈服应力、G’、G” 和 tan δ 等流变数据的测量误差。 UPP 是唯一一种基于 Peltier 的上板加热技术,可以直接对样品进行温度测量。该技术通过 TA 的专有技术主动温度控制 (Active Temperature Control, ATC)1 实现。此技术结合了 TA 的专有热扩散器技术2,将热量直接传导到样品,以实现最精确的温度控制和材料表征,从而满足各种测试需求。 (1) 美国专有号 (2) 美国专有号 特点和优势 专有热扩散器可将热量直接传导到样品上,从而使样品温度均匀,消除测量误差。 通过 Peltier 元件驱动的快速响应的温度控制,可提高生产力。 简单紧凑配置,工作温度范围广泛(从-40°C 到 200°C*),无需液氮或机械冷却器 使用专有 ATC 直接测量样品温度带来了无与伦比的热炉系统(ETC 和 FCO)数据重现性。 保护样品不受环境影响: 溶剂池选项:防止水性样品和挥发性样品的蒸发 热屏蔽:防止湿气凝结…
