OZONE TRANSFER STANDARD The EC9811 Ozone Transfer Standard is a precision ozone calibrator that meets all U.S. EPA requirements for operation as an ozone photometer and ozone transfer standard. The EC9811 includes an in-built ozone generator and internal zero-air source as well as a compact reference photometer, providing precise feedback control for accurate ozone generation and measuring in the one unit. Ozone generation and measurement are automatically corrected for gas temperature/ pressure changes and can be displayed in units of • Self contained transfer standard includes ozone photometer, ozone generator and zero air source within the one portable unit • Capable of measuring and generating accurate ozone calibration levels (Photometer accuracy: 1.0 ppb or 1% of reading, Ozone generator output 0.04 • Easily programmable providing up to five different ozone concentrations with operator selectable time intervals (traceable to NIST/NATA). • Allows users to perform inter station calibrations without disrupting station plumbing, as the EC9811 includes its own zero air generator and inbuilt ozone generator as per U.S. EPA • Capable of measuring internally generated ozone or externally generated ozone enabling station ozone generators to be easily calibrated. • Generation of accurate ozone concentrations through internally stored calibration curve when • Sample flow rate to photometer is operator • Ensures repeatable and accurate readings by automatically compensating for temperature, pressure and flow variations. • Integral output gas manifold, designed to U.S. EPA standards, allows up to 3 instruments to be calibrated simultaneously. • Onboard data storage-stored data can be retrieved via RS232, USB interface or the optional Ethernet connection.
