Functions:
* With 3 1/2 LED, display is clear and precision is high.
* Electrode constant compensation.
* Manual temperature compensation.
* Output signal (0-10)mV.
 
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).
