CO Detector

Model：RMS-350

Overview

Adopting the direct-extraction and electrochemical sensor, the CO detector can continuously monitor the CO (O2) content in the mill, furnace and flue. It is designed for analysing the measured data to prevent the mill from explosions, control the fuel/air ratio to improve the combustion efficiency and give an early alarm upon the high-temp corrosion and coking conditions.
