Summary Specification

Gaseous Emission Analyzer—Original Products Manufactured By American California Analysis Instrument Cooperation

■Main Control Unit

●Using industrial personal computer, industrial personal computer and LCD (liquid crystal displayer) all installed in the 19’’ standard cabinet

●Analysis instrument unit, used by directly insertion of the line or plug

●System conditions tracing and monitoring: having the functions of system condition displaying, help menu, self-test in case of error, returning to the initial status when false operation occurs, displaying the linear test of the analysis system, system interference test, data buffering, monitoring the dilution channel

■Pollutant analyzing unit of the gas emission

●Linearity: ≦±1% F.S

●Repeatability: ≦±0.5% measurement value (same sampling, continuous measurement in the same condition)

●Zero drift: ≦± 1% F.S / within 24 hours

●Calibration gas drift: ≦±1% measurement value/ within 24 hours

■THC Analysis Instrument

●Having automatic ignition and interference check function

●Working principle: Heated hydrogen flame ionized analysis instrument (H. FID

■NOX Analysis Instrument

●Working Principle: Heated chemo-luminescent method (H.CLD)

●Multiple measurement ranges setting

■CO Analysis Instrument

●Working Principle: Non dispersion extra-red light analyzing instrument (NDIR)

■CO2 Analysis Instrument (applying to dilution sampling, and sampling with bag)

●Working Principle: Non dispersion extra-red light analyzing instrument (NDIR)

■O2 Analysis Instrument

●Measuring Range: 0-1~25% (automatic measurement range changing function in each gear)

●Response time (90% F.S): within 3.5 seconds

 Venturi tube

The critical Venturi nozzle is made of stainless steel (1Gr18Ni9Ti) which is good in ther The inlet temperature of the critical Venturi nozzle,i.e. the air temperature coming out from the radiator is controlled within 45°C±5°C.

mo-stability.

Calibration system

Periodically calibrates the CFV-CVS system with a highly accurate laminar flowmeter. There are two options (on line, off line) for the flowmeter.
