If you are looking for a lower cost instrument which qualifies as a near-reference monitor, please contact us about the ES-405.  Because reference monitors are expensive and require shelters and limited locations around your state or country, the alternative is a near-reference monitor and lower cost, ease of deployment and maintenance, as well as reliability in comparison with reference type monitors.  Reference type monitors used in the USA are predominantly the Met One Instruments BAM 1020. The BAM 1020 is also deployed around the world in over 130 countries.  Please contact our sales department for more information and pricing at sales@metone.com or internationalsales@metone.com.

  AirNow, and a New Map to Rule Them All Kevin Stark Sep 4, 2020 Save Article Facebook Twitter Email Copy Link Bay Area residents have become used to the ritual of checking air quality maps for places to escape wildfire smoke that has wafted over from burning forests and chapparal near and far. During the 2018 Camp Fire,  AirNow , an air quality website maintained by a partnership of states, the federal government, Canada and Mexico, crashed because it could not handle so many people flocking online to put numbers to what their noses were telling them: The air seems really bad. The failure sent web users  rushing  to alternative, unofficial websites like the interactive, crowdsourced map maintained by  PurpleAir , a manufacturer of low-cost air monitors. But during this year's wildfires, users have noticed a discrepancy between what official sites are reporting and the readings displayed on PurpleAir. So, What’s the Deal? Broadly put, PurpleAir provides more loc...

Reference, Regulation Monitoring Reference and Regulation monitoring are classified as the highest grade of monitoring instrumentation, given only to those instruments that pass the EPA strict certification requirements. Met One Instruments’ BAM 1020 and BAM 1022 are the dominant Federal Equivalent Method (FEM) products in the US and two of the most successful monitors sold in the world. We also provide both manual and sequential FRM Samplers. The accuracy requirement is ± 10% of the reference standard. Furthermore, an  additional condition exists that the Monitor can operate indefinitely without any site-specific span calibration against a local reference standard .  Met One Instruments, Inc. also offers the E-FRM and the E-SEQ-FRM, which are single-event and multiple-event reference samplers.  BAM-1020 Continuous Particulate Monitor E-FRM Reference Sampler   Personal Exposure Monitoring Personal exposure monitoring may include a wearable sensor or, more typically, ...

Facts of The Last Supper in video. Tecnic SAS and Ario Rupprecht have been monitoring The Last Supper since 2008.   Please watch the video to see why dependable and accurate monitoring must be done for the preservation of the painting. The monitors being used are the E-Sampler and the 212-2 Profiler. Happy Easter!

  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 co...
