FN311A Nitrogen Purity N2 concentration monitor Analyzer

Brief introduction

FN311A Nitrogen Purity Analyzer is a new-type intelligent industrial online analyzer researched and developed by combining imported high-performance electrochemical sensor, which is used to detect oxygen and display nitrogen purity, with new microcomputer technology.

Application fields:

Detecting oxygen content in nitrogen production by air separation, chemical process, magnetic materials, and protective gases for high-temperature sintering furnaces and displaying it as nitrogen purity

Features

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

Small volume and light weight, making the instrument especially suitable for places where the installation space is relatively small;

Automatic range shifting; upper/lower limit alarm can be set at will within the whole range;

Alarm point can be set at will within the whole range;

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