HE-480R(W)

工业级电阻率计

HE-480R 工业级电阻率计具有高精度温度补偿功能。
高性能温度补偿使其成为半导体领域和包括电器、食品和医药领域等许多其他领域制程中连续检测超纯水的理想选择。测量范围从 0 到 100.0 MΩ・cm。

制造商: HORIBA Advanced Techno Co., Ltd.

高精度温度补偿
采用铂电阻温度计（Pt 1000 Ω）作为温度补偿元件。
可自由调节标准温度
可将温度补偿的标准温度设置为选定值，以满足工艺要求条件，如测量加热的去离子水。
我们使用完整的校正设备
传感器在发货前使用具有可追溯性的校正设备进行检查。HORIBA 也提供售后支持服务，包括现场校正，以及如提供校正认证等方式的操作验证。
使用无铅焊料
为减轻环境负担，采用无铅焊料将元件嵌入印刷电路板。
