EC9811 Ozone photometer - Ecotech - #1

Text version of the page

EC9811 Ozone Photometer The EC9811 Ozone Photometer meets U.S. EPA requirements for an ozone analyser and an ozone primary transfer standard. The EC9811 is a compact analyser and primary transfer standard that requires no external pumps or scrubbers. The EC9811 utilises the Beer-Lambert law and UV absorption detection to calculate ozone concentration. O3 measurements are automatically corrected for gas temperature/ pressure changes and can be displayed in units of ppm, ppb, ìg/m3 or mg/m3. • Built in high efficiency sample pump features low noise operation and automatic flow correction. The sample pump provides up to 5 LPM of scrubbed zero air for both the photometer reference cell and the ozone generator. • Photometric dual-channel technique provides reliable measurements. • Single, small glass measurement cell, low sample flow rates and no mirrors means that cleaning and maintenance requirements are minimised. • Built-in secondary ozone scrubber allows independent verification of primary scrubber performance ensuring maximum accuracy and reliability. • Automatic five point span calibration of ozone generator. • Stored data can be retrieved via RS232, USB interface or the optional Ethernet connection and uploaded to a TCP/IP network. • Ethernet option facilitates data download from an analyser connected to the internet via a standard web interface. This feature also supports remote access to instrument parameters and the status output screen . • Inbuilt data logger uses Flash ROM to store up to 175 days of 5 minute averaged data. Features
