FN311C Explosion-proof Oxygen O2 content concentration Analyzer

Brief introduction

FN311C Explosion-proof Oxygen Analyzer is a new-type intelligent industrial online analyzer researched and developed by combining imported high-performance electrochemical sensor with new microcomputer technology.

Application fields:

Oxygen content analysis at locations needing explosion protection in the production processes of such industries as chemicals, building materials, chemical fertilizer, petroleum, biological fermentation, and coal gas

Features

Imported electrochemical sensor adopted, featuring long service life, high accuracy, and quick response;

Chinese menu and human-machine interface, making operation intuitive and convenient;

Large-screen 320×240 lattice LCD, able to simultaneously display parameters like oxygen content, date, and time;

Automatic temperature compensation, eliminating the affect from ambient temperature;

Timed automatic storing function, and stored data and curves available for viewing at any time;

Upper/lower limit alarm can be set at will within the whole range;

Standard RS232 or RS485 communication interface available for two-way communication with computer;

Isolated explosion-proof case adopted, so that the instrument can be directly installed on the site.
