Dynamic Dilution Calibrator
Tripurari Enterprises Supplier and Distributor of AAQMS in India.
Tripurari Enterprises multi-gas calibrator utilizes mass flow controller to perform standard zero and span calibration with up to 4 gas sources.
Key Features:
• Stable trace level ozone output down to 0.1 ppm
• Optional ozone generator, gas phase titration and photometer for independent ozone calibration
• User selectable output include RS232
and Ethernet
• High performance mass flow controller provides stable and linearized output
Principle:
Tripurari Enterprises 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.
