| 1.Measuring range: |
| The measuring range is (0~2×105) uS/cm. The instrument has five ranges and can be changed through band switch by manual (by electrode with constant). |
Range | Measuring range | Resolution | 2 uS/cm | 0.001~2 uS/cm | 0.001 uS/cm | 20 uS/cm | 0.01~20 uS/cm | 0.01uS/cm | 200 uS/cm | 0.1~200 uS/cm | 0.1uS/cm | 2 mS/cm | 0.001~2.mS/cm | 0.001mS/cm | 20 mS/cm | 0.01~20 mS/cm | 0.01mS/cm |
|
| NOTE: To measure high conductivity, a larger constant electrode is commonly used. If the conductivity is over 10000 uS/cm, the electrode with constant of 10 cm―1 is used and the measuring range is extended to 2×105 uS/cm. |
