Introduction

Gasboard 3000Plus is designed with world-leading micro-flow infrared sensor, is able to measure continuously simultaneously concentration of CO,CO2,SO2,NO,especially for lower range measurement. It is an ideal solution for monitoring in fields of boiler, power plant, combustion efficiency monitoring for various industrial furnaces or refuse incinerator, process and security monitoring.
