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.

Measure thermal properties across a wider range of materials with confidence with the TEMPOS Thermal Properties Analyzer.

The TEMPOS measures thermal conductivity, resistivity, diffusivity, and specific heat in materials ranging from soil and concrete to insulation, food, plastics, oils, and more.

Its needle probes produce only a small amount of heat, reducing moisture movement and helping ensure accurate readings—even in wet materials, frozen samples, and liquids.

Soil water potential is vital to understanding the water status of your plants. Unfortunately, it’s easy to get lost in trying to understand all the complexities of the formula. But just like temperature, you don’t have to know why it works, just in what range your plants are happiest.

In this episode of Office Hours, Chris Chambers, and Leo Rivera answer submitted questions about water potential.

Potatoes can be sensitive to both under irrigating and over irrigating throughout the growing season. Soil moisture measurements can help guide irrigation timing and provide insight into field conditions that may influence crop quality, storage performance, and disease pressure.

Hear why managing moisture carefully became an important part of this grower's irrigation approach.

Episode 52: Protecting water resources while producing energy with agrisolar designs

In the central United States—and other agricultural areas around the world—irrigation will become more difficult in the near future. PhD candidate James Bingaman is studying how solar panel arrays can help conserve and recharge groundwater in impacted areas, keeping land arable and producing energy to meet growing demand.

Environmental scientists, researchers, and field teams often rely on measurements from multiple sensors to better understand complex environmental conditions.

ZENTRA combines sensors, data loggers, and cloud-based software into one system designed to support field measurements, provide near real-time data access, and streamline visualization across soil, plant, and atmospheric monitoring applications.

Spend less time managing data and more time doing what matters.

This week, we celebrate the anniversary of the Phoenix Scout Lander Mars landing—a mission that not only changed space exploration but also quietly highlighted the power of soil science.

When Phoenix touched down on May 25, 2008, it carried something unexpected: a piece of soil measurement technology developed here on Earth by METER scientists. Originally designed for use in soils, our sensor was chosen by NASA to help understand Martian regolith.

The TECP sensor that flew to Mars was part of an early collaboration between NASA’s Jet Propulsion Laboratory, our co-founder Dr. Gaylon Campbell, and his team of scientists. Seventeen years later, we're still exploring new scientific frontiers.

To our fellow scientists, engineers, and dreamers: thank you for always pushing the boundaries of what’s possible.

Innovation in Action

During a recent trip, we had the opportunity to visit with Kendall Shelton and her team of crop physiologists at the West Tennessee AgResearch and Education Center.

The center is a major hub for agricultural research in the region. Scientists from several university departments, along with USDA-ARS researchers, conduct more than one hundred investigations annually, focusing largely on major agronomic crops including corn, cotton, soybeans, and wheat.

Kendall hosted a workshop where we discussed soil moisture measurements in crop physiology and the importance of ET for understanding plant–water relationships. Discussions included how soil moisture sensors and atmospheric measurements can be used together to better understand crop water use, plant stress, and irrigation management in field experiments.

Scientists and engineers often compare measurements across different soil moisture sensors under a range of field conditions.

Join METER scientists Chris Chambers and Leo Rivera as they discuss CDX technology.

This discussion looks at how soil-specific calibration, overlapping installations, and natural spatial variability can influence comparisons between TEROS 12 and SOLYX 14 measurements.

It also highlights an important point in field measurements: differences between sensors do not always mean something is wrong.

“I used to think I was a really good irrigator. Then I started using sensors, and I realized I have a lot to learn.”
— Dr. Bryan Hopkins, Soil Scientist, Brigham Young University

By combining water content and water potential measurements, growers can better understand plant available water and help guide irrigation decisions throughout the season.

We were founded by research scientist Dr. Gaylon Campbell, and his scientific perspective continues to influence how
we approach measurement challenges today.

Many of the same instruments used by growers, scientists, and engineers in the field are also used by METER scientists in research projects around the world. That shared experience helps support conversations around measurement interpretation, irrigation management, field conditions, and data quality.

Hear how field and research experience shape the way we support measurement work throughout a project lifecycle.
