  We are proud to introduce the ES-412 Portable Simultaneous Particulate Profiler to our easy-to-use near-reference instrumentation line of products. As a Near-FEM (Federal Equivalent Method) product,  this lightweight Particulate Profiler offers wireless, remote PM monitoring in a low profile, deployable field instrument. The weatherproof unit measures PM2.5 and PM10 simultaneously with instant access to data on smartphones, tablets, or computers. Data from the ES-412 is backed up internally and then transmitted to a nearby cell tower every 15 minutes. In cell tower communication loss, the ES-412 will attempt communication continuously until it connects again. When this occurs, the ES-412 will transmit all missing data. Transmitted data contains 15-minute averages for PM2.5 and PM10 with information on device power, flow, and internal diagnostics. The custom web page dashboard offers a map showing the unit's location with an internal GPS module. The ES-412 is a system that comes c

Met One Instruments, Inc. is the Parent Company of Belfort Instruments

                         Model 6400 All Environment Visibility Sensor The Belfort Model 6400 Visibility Sensor is designed to monitor visibility conditions over a range of 20 ft-50 miles (6m-80km). 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 provide access to the configuration and calibration options. The SPDT relay with configurable pull in and drop out set points can provide signals to a VMS or other optional user system. Belfort has applied its 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 now features ease of field serviceability. Applications include synoptic stations, lighthouses, highways, resort areas, as well as shipboard


Photos of the South Korean Coastguard ship with air monitoring equipment, including the Met One Instruments, Inc. BAM 1020 PM monitor. System appropriated by JS Airtech in Seoul.  JS Airtech has installed our equipment on land, on the sea, and in subways and underground shopping areas throughout South Korea. It has been exciting to work on these projects. Kamsahamnida!   

Our apologies to Our Distributor, Ali Al-Aufy Trading Co. in Oman....

   The installation location is in  Oman- Salalah Airport Project site.  The photos were mistakenly attributed to a project in Saudi Arabia in an earlier post.  The installation consists of the BAM 1020 and a weather station provided by Met One Instruments, Inc. to Ali Al-Aufy Trading Co., our long time distributor in Oman.

JS Airtech Projects in Busan City At Transportation Sites....

Monitoring in buildings, subways and indoor sites requiring PM monitoring to protect people who work and travel in various indoor situations. JS Airtech installs and maintains these sites using the BAM 1020 PM monitors as well as gas analyzers.  South Korea is extremely advanced in the installation of air quality monitors around their cities, indoors and out.

  BAM 1020 MONITORING AT THE CASTLE Enviro Technology monitors at the Cardiff Castle with the BAM 1020 for both PM10 and PM2.5. Cardiff Castle is one of Wales’ leading heritage attractions and a site of international significance. Located at the heart of the capital, within beautiful parklands, the Castle has nearly 2,000 years of history just waiting to be explored. It all started in the 1st century AD by the Romans who built the first in a series of forts. In the 11th century, the Normans constructed the Keep that still dominates the Castle Green to this day. The medieval Lords of Glamorgan began work on the House during the 15th century. The Bute family left their mark on the entire city in the 19th century, they also transformed the House into the opulent Victorian Gothic home it is today. During World War II the walls which surround the Castle were used as air raid shelters; a place of safety for thousands of Cardiff citizens. A reconstruction of the shelters has been opened for v


With the coronavirus pandemic still very much an ongoing concern, Dr. Fauci  during an interview  earlier this year said that buying a HEPA filter can help prevent the coronavirus from spreading inside the home. Fauci’s recommendation is certainly worth taking seriously because indoor gatherings have been shown to be disproportionately responsible for coronavirus outbreaks. This is largely due to the fact that the coronavirus can spread more readily in confined areas with extremely poor air circulation. To confirm your hepa filter air cleaner is working correctly, you will need a particle monitor like the Met One Instruments Aerocet 831.  The Aerocet will immediately confirm your hepa filter is cleaning the air inside your room and functioning correctly.  The Aerocet is used by the most popular and reliable air cleaning monitor manufacturers as confirmation of their functionality.
