Visibility Sensor / Nephelometer

Met One offers time-tested and reliable weather sensors that serve meteorological monitoring needs throughout the world. Met One's robust prodcuts are able to measure wind, temperature, relative humidity, rainfall, solar radiation, atmospheric pressure, and visibility, in the face of torrential rain, snow and ice, extreme heat and drought, and every kind of weather nature manifests.

The Met One Model 6400 Visibility Sensor is designed to monitor visibility conditions over a range of 6-80000m. The Model 6400 includes both digital and relay outputs. Digital RS232 output at 300...38'400 Baud can be used to indicate the present visibility, provide diagnostic information, and allow for access to the configuration and calibration options. The SPDT (Single Pole Double Throw) relay with configurable pull-in and drop-out set points is able to create signals to a VMS (Variable Message Sign) or other optional user system.

Met One takes advantage of Belfort Instrument's proven experience with visibility technology in re-designing this new sensor for applications which require high accuracy over an extended range of visibility. These sensors are designed to provide both accuracy and reliability in a cost effective package. The Model 6400 features easy field serviceability. Applications include synoptic stations, lighthouses, highways, resort areas, as well as shipboard and other marine platforms.

Nephelometer is an important instrument in a variety of Air monitoring applications. Many organizations throughout the world including environmental protection agencies, meteorological agencies, universities, airports, and federal, state and local governments use nephelometers everyday in a variety of ways. The Ecotech Aurora series of nephelometers are the broadest and most cost effective nephelometer range on the market.

Aurora 1000 Integrating Nephelometer - Easy to use and maintain / lower cost of ownership for aerosol light scattering, visibility and particulate monitoring instrumentation.

Aurora 2000 PM2.5 Correlating Nephelometer - a part of the 'new generation' nephelometers using a single wavelength / an Beta monitor to measure aerosol light scattering and derive particulate concentrations.

Aurora 3000 3 Wavelength Integrating Nephelometer - favoured choice of researchers / simultaneous measurement across three wavelengths, enabling wide and in-depth analysis of the interaction between light and aerosols / integration of measurements of full scatter and backscatter / a perfect instrument for climate change research.

Aurora 4000 Polar Integrating Nephelometer - the world's first commercially available polar nephelometer / measurements of integrated light scattering between 10°- 90° and 180°, with the user able to select up to 18 separate angles between the 10° to 90° starting angle of the integration.
