METER Group

METER Group METER designs scientific instrumentation that delivers real-time, high-resolution environmental data. In 2016, two firms merged. Each was successful on its own.

Each had a unique focus. They were brought together by strong common values, similar roots, a history of collaboration, and shared expertise in science and engineering. The unified company combines the strengths of both firms to create powerful synergy, competitive advantage and new business opportunities. To know where you are going, you must know where you came from. Let’s take a moment to look

back. FROM PULLMAN TO MARS

Decagon Devices, Inc. was founded in 1983 by Dr. Gaylon Campbell, a renowned soil scientist and faculty member at Washington State University. The first Decagon product was an instrument to measure water in soil. Decagon quickly realized that other customers could benefit from their expertise in measuring water. New markets like food safety, pharmaceuticals and other industries needed solutions to determine water content and water potential in their products. Over the next 30 years, Decagon improved and expanded their expertise in engineering sensors, all while maintaining affordable product offerings. Today, Decagon products are used all over the world and even beyond: in universities, research and testing laboratories, government agencies, vineyards, farms and industrial applications – even on Mars. GERMAN SCIENTIFIC ENGINEERING

UMS AG was founded in 1989 by Georg von Unold, a mechanical engineer who was working at the renowned Helmholtz Research Center in Munich, Germany. The first UMS product was a scientific instrument for soil irrigation control. The tensiometer sensor series was quickly adopted by scientists due to its precision and reliability. To date, more than 20,000 UMS tensiometers have been used in research projects worldwide. In 1991, the product range was extended to cover environment monitoring systems – from proprietary sensor technology and the development of innovative components to planning and providing individual customized solutions. OUR DNA

8,367,180 meters. That’s precisely the distance from the doorstep of the headquarter in Pullman to the entrance of the headquarter in Munich. The businesses seem a world apart. But if you take a closer look, you will see that the people in these two places have always been much closer:

Both companies were founded by individuals who are passionate about measuring the natural environment. Both founders were initially driven by their own needs, but quickly saw that they could create products for their colleagues. Both companies share a drive to invent rather than follow. Both companies are committed to marketing through educating our clients. In Pullman as well as Munich, we speak the language of scientic engineering. In both places, the corporate culture is built around the importance of employees. We build a strong foundation on common ground, and our differences are complementary. Pullman has expertise in measuring the dry end, Munich the wet end. While Pullman excels in science and simplicity, Munich does so in engineering and precision. For over a decade, we’ve worked together in product development, supply and distribution, customer support and education. That was enough time to detect a clear fit and to decide to take the next step.

Actual evapotranspiration is shaped by the exchange of water and energy between the land surface and atmosphere. Measuring it in the field requires more than a single weather variable.

The ATMOS 51 VBR combines high-frequency temperature and humidity measurements with solar radiation data to support field-scale actual ET measurement using the variance Bowen ratio method. Its compact design makes it possible to expand actual ET measurements across additional locations or use them alongside existing weather stations and eddy covariance systems.

When every millimeter matters, approximations based on a regional weather station miles away are rarely precise enough. Join our upcoming webinar to learn how modern measurement methods improve the accuracy of precipitation data.

On September 3 at 9 a.m. PDT, METER Product Scientist Jeff Ritter will compare precipitation measurement methods and explain how sensor location and measurement accuracy can affect the usefulness of rain, snow, and fog data. The 30-minute webinar will also cover tools for visualizing precipitation across multiple measurement sites.

Particle size tells only part of the story when designing soil for a baseball infield.

Evan Mascitti, Assistant Professor of Urban and Managed Landscapes at UMass Amherst, explains how clay mineralogy and mix ratios influence the properties of engineered infield soils—and why different recipes can produce comparable performance. His work connects soil science with the practical demands of athletic-field safety and playability.

Choosing a weather station means weighing more than price and performance.

In Office Hours 19, Jeff Ritter and Chris Chambers explain how application risk, spatial variability, reliability, and maintenance expectations shape weather-station selection. The episode also covers calibration, microclimates, modular versus all-in-one systems, and field measurements alongside virtual weather data.

Understanding water and energy exchange at field scale often requires measurements that are difficult to expand across multiple sites.

ATMOS 51 uses the variance Bowen ratio method to directly measure actual evapotranspiration (ET). Its compact setup can support researchers who want to supplement an eddy covariance footprint, add measurement locations, or pair actual ET with precipitation and soil moisture data to study water movement through a system.

Weather data from six miles away wasn’t enough to document conditions on a road construction project. For Bryce Wuori, co-founder and CEO of Pavewise, that experience reinforced the value of monitoring weather directly on-site.

In this episode of We Measure the World, Bryce explains how localized weather measurements support project scheduling, compliance documentation, and decisions when conditions change.

Can virtual weather data replace an on-site weather station?

While virtual weather models can be useful for broad estimates, on-site weather stations provide measurements of the actual conditions at your location. Understanding the strengths and limitations of each approach can help you choose the right data source for your application.

The Variance Bowen Ratio method provides actual ET measurements with less complexity than traditional eddy covariance systems, so you can scale ET measurements to your application.

Watch the latest episode of Office Hours, where METER scientists Dr. Daniel Beverly and Jeff Ritter answer questions about evapotranspiration (ET) and the Variance Bowen Ratio (VBR) method, including a comparison between use-cases for reference ET, crop ET, and actual ET.

What works at one measurement site may not scale to more.

Hear how Daniel Beverly, research scientist at METER Group, explains why empirical crop-water-use methods can become less reliable as operations expand or conditions shift. The ATMOS 51 VBR Actual ET Sensor directly measures actual evapotranspiration, helping agronomists and agricultural teams compare crop water use with reference metrics using field-based data.
