Features :
Computer-based: Multi-parameter measurement, temperature compensation and automatic range |
conversion are achieved thanks to the high-performance CPU chip, high-precision AD conversion technology |
and SMT pasting technology, resulting in high precision and repeatability. |
Reliability: Touch keys, no switch knob or potentiometer. |
Automatic conversion of measuring frequency: Electrode polarization avoided and measurement accuracy |
enhanced. |
Alarm: Isolated output of alarming signals, discretionary setting of upper and lower thresholds for alarming, and |
lagged cancellation of alarming. |
Network function: Isolated current output and RS485/RS232 communication interface. |
Isolated current output: Discretionary setting of upper and lower thresholds of current corresponding to the |
conductivity |
