Tripurari Enterprises Instruments Supplier and Distributor of AAQMS in India.

Sulphur dioxide (SO2) analyzer for monitoring the So2 Levels in ambient. It applies UV fluorescence technology recommended by US EPA as federal reference method for trace level SO2 measurement of AAQMS.

Key Features:
• Compliance with US EPA reference method
• Various outputs include Ethernet and RS232
• User friendly interface with large screen
• Continuous system diagnosis with alarm
• Multi-tasking software allows viewing test variables while operating
• Temperature and pressure compensation
• Internal data logging with 1 min to 365 day multiple averages
• Critical orifices provide flow stability

Principle:

Tripurari Enterprises Instruments measures the intensity of the characteristic fluorescence released by SO2 in an ambient air sample contained in the gas chamber when the air sample is irradiated by ultraviolet light passed through the chamber.

UV source:

The pulsing of the UV source lamp serves to increase the optical intensity whereby 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 storage 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.
