AS2000 Continuous Emission Monitoring System

Introduction AS-2000 comprises sampling subsystem, gas measuring subsystem, smoke measuring subsystem, auxiliary parameter meas

Features

l         Automatic analyzing the concentration of one or more components of the concentration of SO2,NO,CO,CO2,O2,C2H4 and gaseous pollutant in the mix gas, but also detecting the discharge flue dust in the fume and the monitoring of process parameters;

l         Measuring results will be stored in the data sampling control system automatically;

l          All kinds of ways of transmission can be compatible, multi-levels networking;

l         Standard modular design, easy to maintain, upgrade and expand;

l         CEMS system can be self-diagnosed, including invalid probe and detecting source, range exceed alarm, breakdown of main units alarm, timely fault notice during the operation;

l         Site data timely transferred, fault remote diagnosis;

l         Auto-calibration zero by air(<3%CO2 must use N2 calibration zero);

l         Data can be collected, stored, handled and distinguished by data system, which can control the daily construction of CEMS, including cycling auto-correction, auto-reverse blowing probe and filter of sampling system, providing the information what approved test and monitoring needed;

l         Multichannel 4~20MA analog output and relay contact output;

——high-accuracy, stable

——short preheating time-5mins

——bilingual menu operation

——User can do the man-machine interaction through keyboard and LCD in the front  

——system can non-stop operate at least 90 days with no need for daily maintenance

——Interval time: one adjusting every 1-6 months according to environmental condition

——easy to use, operate and set, low-cost, low work load for maintain
