Acoem Aurora 1000 Integrating Nephelometer spec
Aurora 1000 Integrating Nephelometer Easy to use and maintain, the Aurora 1000 lowers the cost of ownership for aerosol light scattering, visibility and particulate monitoring instrumentation. The Aurora 1000 Integrating Nephelometer (formerly known as the Ecotech Aurora 1000) uses a single wavelength for scattering coefficient visibility measurements at one of three user specified wavelengths. Acoem, through collaboration with globally renowned atmospheric research institutes, now provides the scientific community with the most advanced commercially available nephelometers. Using a single wavelength LED light source, the Aurora 1000 can be equipped with any of the following light sources: • 450 nm (blue) for fine & ultra fine particulates (wood fires, automobiles) • 525 nm (green) for visibility • 635 nm (red) for large particulates (e.g. pollen, sea salt). BENEFITS • Simplified automatic calibration using internal valves, ideal for remote locations. Fully automatic zero check or adjust, automatic span check or automatic zero & 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 & 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 < 90 % ) • 12 VDC operation (60 W max, 13 W nominal) • Stores up to 61 days of 5 minute data or 12 days of 1 min data. • Free Airodis demo version & firmware upgrade software supplied on USB or via Internet • Remote control through serial interface • Our LED light source is guaranteed not to fail within 3 years & often exceeds 5 years life time • 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 Increased accuracy • Automatic calibration • Easy maintenance/cleaning of the measurement cell • Long lasting LED light source • Intuitive software & maintenance • Automatic optical reference calibration • Facilitates a wide measurement range (0 to 20,000 Mm -1 ). Lower cost of ownership • Fully automatic zero & span calibrations • Low power internal 12 V heater eliminates the need for external inlet heater • No bandpass filters to be replaced • Unique in its simplicity & practicality.
