YANTAI STARK INSTRUMENT CO., LTD.

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.

Alarm: Isolated output of alarming signals, discretionary setting of upper and lower thresholds for alarming, and

lagged cancellation of alarming.

Isolated current output: Discretionary setting of upper and lower thresholds of current corresponding to the

Conductivity.
