011 Wind Speed Sensor for Wind Energy Resources

      – The 011 Wind Speed Sensor has been designed to meet Class 1 performance criteria established by the International Electro-technical Commission (IEC 61400-12-1). Based upon the 25 year field-proven 010C platform and it features a new cup design to optimize cosine response, and a new connector to accomodate existing and new applications.  The 011 Wind Speed Sensor is manufactured in the United States at our factories in Grants Pass, Oregon. For more information and pricing, please contact

Happy Holidays!

                                                Holiday Greetings from Met One Instruments To all our valued customers and partners, we wish you joy and good health for the New Year! From the Friendly Crew at Met One Instruments, Inc. We Can Do It!


MSO compact weather station with wind speed, wind direction, temperature and relative humidity and barometric pressure generates lots of interest at the Solar Power exhibition in Mumbai, India. For more information, please contact or

Met One Instruments' E-Sampler and PARTICLE FALLS KINETIC ART

Particle Falls About this video: "Although air is invisible, it has a major impact on public health. Santa Clara County received a failing grade for air quality in the American Lung Association’s 2009 State of the Air Report and currently surpasses unhealthy short-term pollution particles a yearly average of 11 days, the 24th highest level in the US. The number of people that airborne particulate pollution kills each year has tripled in California. Despite the invisibility of air, modern sensors can detect tiny particulate pollution levels in real time. Particulate pollution can be measured by laser light scattering, and Particle Falls provides a real time visualization of particulate pollution in the San Fernando Corridor using the latest projection technology. The project focuses on the smallest particle, PM2.5, since the global monitoring of it is one of the most recent developments in aeronomy."

World Health Organization on AQG for PM

Based on the existing evidence of adverse health effects at low levels of exposure, WHO revised its AQG for PM in 2005 (1). For PM2.5, the new AQG values are 10 μg/m3 for the annual average and 25 μg/m3 for the 24-hour mean (not to be exceeded for more than 3 days/year). The corresponding guidelines for PM10 were set as 20 μg/m3 and 50 μg/m3.

COLLEGE PARK, Md. – Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall and the intensity of severe storms in wet regions or seasons, says a new study by a University of Maryland-led team of researchers. The research provides the first clear evidence of how


 The Met One Instruments, Inc. model ES-642 is a type of nephelometer which automatically measures real-time airborne PM10, PM2.5, or TSP particulate concentration levels using the principle of forward laser light scatter. Sample air is drawn into the ES-642 and through the laser optical module, where the particulate in the sample air stream scatters the laser light through reflective and refractive properties. This scattered light is collected onto a photodiode detector at a near-forward angle, and the resulting electronic signal is processed to determine a continuous, real-time measurement of airborne particulate mass concentrations.                                            ES-642 AMBIENT PARTICULATE MONITOR Applications include rail and roadside monitoring, schools and playgrounds, underground facilities, solar power installations, wind energy installations, farms and ranches, and hotels and public venues. Also, the ES-642 is installed  with other particulate monitors suc

MOI Introduces the 011 E-Class One Wind Sensor


To our readers, I recently returned from Shanghai where my company, Met One Instruments, Inc. participated in a technology exchange with the Shanghai Academy of Environmental Sciences.  Along with Oregon's Governor, Dr. John Kitzhaber, we made a presentation of our EPA Reference Method Air Quality Monitor.  BAM-1020 PM 2.5. The BAM-1020 is a US manufactured particulate monitor that monitors particles in the range of PM10 and PM2.5.  The monitor presented to SAES will be one of the first PM2.5 monitors deployed in Shanghai. This was my fourth trip to Shanghai in the past 3 years and I was impressed by the number of blue sky days that I was able to experience.  (See Pics)  I noticed that surfaces of infrastructure (buildings, windows, railings, street lamps, etc...) were generally free of particulate fall out.  One afternoon, I spent a few hours wandering around Shanghai on a quest to find xiaolongbao and an electric bicycle dealer and had a very pleasant time.  T
