Catalog excerpts

AMMONIA ANALYSER combines a high performance ammonia converter and proven chemiluminescence detection to measure ammonia (NH3 ), oxides of nitrogen (NOx) and total nitrogen compounds (Nx). Nx is the sum of NO+N02+ NH3 i.e. total oxides of nitrogen including ammonia. converted to NO in a quartz converter heated to passed through a molybdenum converter heated to approximately 325°C.The resulting NH3 concentra- tion is determined by subtracting the Nx result from • High temperature NH3 converter uses Pt catalyst with a conversion efficiency of > 92%. • N02 to NO converter has less than 3% conversion • NH3 ranges 0-50 to 2000 ppb. (other ranges are • EC9842 analysers have independent Nx and NH3 analogue output channels. • Inbuilt data logger uses Flash ROM to store up to 135 days of 5 minute data averages • Stored data can be retrieved via RS232, USB nterface 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

Ranges display: 0 - full scale from 0-50 ppm/0-2000 ppb with 0%, 5%, 10% offset. Auto-ranging between two user specified full-scale values. Zero offset on NOx and 0.25 ppb of concentration reading with Kalman filter Lower detectable limit: 0.5 ppb with Kalman filter active. Zero drift: 0.2 ppb per °C Time dependent at fixed temperature. 24 hours: less than 1 ppb. Span drift: 0.2% per °C. Time dependent at fixed temperature 24 hours: 0.5% of reading: 30 days: 1% of reading Temperature/Pressure compensation: Temperature/Pressure compensation with selectable Better than 0.5% of reading with...
