电导率标准

在工廠與實驗室中經常使用導電率標準液，可確保儀器始終正確校準，以獲得精確讀值。將探針置入具有已知導電能力的溶液中，可在測試前調整設備設定。設備維護允許估算樣品中存在的雜質與離子濃度。符合產業規範，這些溶液是在嚴格控制條件下製備，以確保完整的操作穩定性與可靠性。

Conductivity standards

Supplier: METTLER TOLEDO

A slight change in temperature usually has a big impact on the conductivity value of a standard solution. A table on every bottle label indicates the conductivity values at the most common measurement temperatures.
During calibration the meter automatically references to this table for temperature compensation. If possible, calibration and measurements should be performed at the same temperature
