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.

Useful soil moisture data starts with the research question.

METER’s Complete Guide to Soil Moisture walks through why soil moisture matters, how it can be measured, method comparisons, where to measure, how many measurements may be needed, and key terms used to interpret field data, so researchers can frame and answer the question.

Soil moisture conditions can shift by depth.

TEROS 54 provides research-grade soil water content and temperature measurements at four depths throughout the soil profile. The profile probe design simplifies installation and removal. Connecting the sensor to a ZL6 data logger and ZENTRA Cloud lets research teams use any web-connected device to understand what is happening below the soil surface.

Good crop management starts with understanding stress.

Experts explain why knowing a plant’s critical points matters and how controlled stress can be used intentionally, depending on crop goals and quality targets. The focus is on choosing the right indicators, especially soil water potential, to set clear thresholds and manage stress consistently over time.

Learn how applied research bridges the gap between scientific studies and real on-farm challenges. Researchers help farmers decide where to place sensors, what to measure, and at what depth, turning complex science into practical field decisions.

The result is more control, less guesswork, and measurable impact. Farms that adopt sensor-based irrigation often reduce water use by around 30 percent, while maintaining yield and improving quality. More importantly, they gain confidence in every irrigation decision.

For fruit tree growers, freeze protection often depends on knowing when conditions are approaching a critical range.

Hear how Katie used ZENTRA Cloud to chart air temperature sensor data and set threshold alerts, helping one grower receive a text message when conditions needed attention. That kind of near-real-time insight can support more confident decisions when every cold night does not require the same response.

Understanding how plants respond to changing environmental conditions requires a wide range of measurements.

Hear plant physiological and chemical ecologist Natalie Aguirre discusses how plant measurements are used to study plant hydraulics, stomatal conductance, and plant responses to changes in moisture over time.

Your sensors can be installed and configured in an afternoon, but you will collect data through their full operational life.

That’s why data visualization is important.

ZENTRA Cloud makes it easier to access and visualize data, helping you get to meaningful insight faster.

"Seeing the differences in each of the [soil] depths all across the field has been instrumental in keeping the vineyard healthy and thriving. What we see here is because I was able to water correctly by actually looking at the data, interpreting it, and then using what I see to adjust my irrigation scheduling.”

Hear how learning to interpret soil moisture data changed the way this grower approached irrigation management in her vineyard.

Have you ever wanted to check a crop's water stress level as easily as you could check the temperature? Established crop water potential preference ranges can help interpret when plants may be experiencing stress and how available water is in the soil.

Soil water potential measurements are used to better understand plant water conditions in the field and support irrigation decisions throughout the season.
