Aurora 1000 Integrating Nephelometer - 1

INTEGRATING NEPHELOMETER Easy to use and maintain, the Aurora 1000 lowers the cost of ownership for aerosol light scattering, visibility and particulate monitoring The Aurora 1000 monitor uses a single wavelength for scattering coefficient visibility measurements at one of three user specified wavelengths. Ecotech, through collaboration with globally renown atmospheric research institutes, now provide the scientific community with the most advanced commercially available nephelometers Using an innovative single wavelength LED light source, the Aurora 1000 can be ordered with one of the following light sources • 450nm (blue) for fine and ultra fine particulates (wood fires, automobiles) • 635nm (red) for large particulates (e.g. pollen, Increased accuracy • Easy automatic calibration, ensures repeatability of • Automatic optical reference calibration • High powered LED light-source increases measurement accuracy. • Facilitates a wide measuring range • Simplified automatic calibration using interna valves, ideal for remote locations. • Fully automatic zero check or adjust, automatic span check or automatic zero and span check available in intervals of 1, 3, 6,12, 24 hrs or weekly. • Fully integrated package including; internal sample pump, sample heater, internal calibration valves, zero air pump and data logger. • Internal sample heater with temperature or RH control, which can be enabled by the user to eliminate the effects of humidity (RH: <30% to • 12 VDC operation (60 watts max, 13 watts • Holds up to 61 days of 5 minute data averages or • Data downloader and Firmware upgrading software supplied on CD or internet. • Our LED light source is guaranteed not to fail and often exceeds 5 years compared to a flash lamp that is recommended to be changed every 4-6 • Heat generated by the LED light source is a fraction of that generated by a flash lamp, minimising changes in sample RH • LEDs emit light at a specific wavelength eliminating the need for band pass filters Lower cost of ownership • Fully automatic zero and span calibrations • Low power internal 12V heater eliminates the need for external inlet heater. • Long lasting low power LED light source. • No bandpass filters to be replaced • Unique in its simplicity and practicality.
