1          Introduction

CI-IN261 produced by Chang Ai Technology & Development Company is a CO2 analyzer that based on NDIR principle. It adopts digital processing technology as zero point/range point calibration, linear processing, temperature compensation, switch output, flow/voltage output, parameters setting ect. CI-IN261 analyzer has good intelligence, high precision, which applies to various industries and environment to test CO2 concentration.

2          Typical Application

   Air production and manufacturing;

   Gas detection in petrochemical process;

   Protective gas detection in industrial process.

3          Main features of CI-IN261

 NDIR,sensor does not touch tested gas, sensor poisoning will not happen;

 Good intelligence, stability, high reliability and long calibration cycle;

Composed of 128×64 LCD to show CO2 concentration, menu, set data and instrument working state, one piece of toughened glass is covered on the surface of screen, protecting LCD and buttons;

Menu lock function, prevent negative impact of error operation on analyzer;

Latest touch key technology, extending service life of button

Two-way single-pole single-throw alarm function;

RS485/RS232(optional)two-way communication function,connect to computer or other digital equipment to communicate;

One combination of isolated analogue output signal, which can be set 4-20mA, 0-20mA or 0-10V of analogue output mode;

Easy structure, operation and maintenance.
