Microcomputer: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT

technology to complete the multi-parameter measurement, automatic temperature compensation and instrument

self - checking, with high precision and good repeatability.

Reliability: All the component are arranged on one circuit board. No complicated functional switch, adjustment

knob and potentiometer.

Strong interference immunity: The current output and alarm relay adopt optoelectronic isolating technology,

strong interference immunity and the capacity of long-distance transmission.

Automatic alarming function: Isolated alarming signal output, discretionary setting of upper and lower thresholds

, and revocation alarm hysteresis.
