The AAQMS-500 Sulphur Dioxide (So2) analyser delivers precise and reliable performance at excellent value. It uses proven UV Fluorescence technology with standard range 0~100 ppb and 0.5 ppb detectable limit.

UV Source

The Pulsing of the UV source lamp serves to increase the optical intensity where by a greater UV energy throughput and lower detectable concentration are realized.

Removal of Interferences

The permeation scrubber acting as hydrocarbon kicker removes aromatic hydrocarbon such as xylene and naphthalene which causes interference.

Optical filtering are employed to improve the rejection of interference from high nitrogen oxides.

Data stroage and analysis

Stored data are easily retrievable through the serial or ethernet port via PC client software, allowing operators to perform predictive diagnostics and enhanced data analysis by tracking parameter trends.

Key Features
  • Critical orifices provide flow stability
  • Various Outputs Include Ethernet and Rs232
  • User Friendly interface with Large Screen
  • Multi-Tasking software allows viewing text variables while operating
  • Internal Data logging with 1 min to 365 days Multiple averages.
