YANTAI STARK INSTRUMENT CO., LTD.

English LCD display, English menu operation, English notepad: It adopt menu structure similar to computer

Operation, simple operation, the steps throughout the English tips, without instructions, it can be completed

Multi-parameter display: The concentration value, temperature, time and status can be displayed on the screen

at the same time.

Intelligent: On-line Fluorine Ion Detector adopts high-precision AD conversion and single chip microcomputer

processing technologies. It can be used for the measurement of the Fluorine ion concentration value and

temperature, automatic temperature compensation, self-checking etc various functions

Reliability: All the components are arranged on one circuit board. No complicated functional switch and

adjusting knob

Strong interference immunity: Its current output adopts optoelectronic isolating technology. This meter has

strong interference immunity and the capacity of long-distance transmission as well as excellent

electromagnetic compatibility

Automatic timing calibration: It can ensure the stability and reliability of the measurement instrument
