Introduction

Linker Oxygen sensor module uses ME series O2 sensor, and have low consumption , small size, high sensitivity , wide range of linearity , and better anti-jamming capacity, good reproducibility, stability and reliability ect advantage . It is electrochemical sensor widely suits for mine, industry and environmental protection field ect.
