The 9220 is an online TOC analyzer that employs Heated Persulfate Oxidation with NDIR detection methodology. Standard features include four-stream analysis capability, onboard carrier gas generation, autocalibration, auto validation, and intuitive software with touchscreen operation. The 9220 is self-contained in a mounting panel with a reagent tray for quick and easy installation and commissioning. Connectivity is provided through four 4-20mA outputs (one for each sample stream), Modbus, and discrete alarm outputs. The 9220's reliability and low-maintenance design ensure reliable data collection with minimal effort.
