             Most weather stations are cluttered, complicated, and frustrating to install and maintain. Wiring and programming can be a nightmare, and finding room to mount everything is a challenge. All-in-one weather stations solve these problems, but the tradeoff is flexibility. Adding just one more sensor often requires an extra logger, making the system more complicated and more expensive.

More measurements. Less work.

The ATMOS 41 weather station is the first affordable, research-grade all-in-one weather station that fulfills all your weather monitoring needs but doesn't restrain you when you want to make other measurements. All weather data (e.g., humidity, temperature, or atmospheric pressure) are transmitted over a single wire. That means you don't have to use all of the ports on your data logger just for weather measurements. And, if you are using the ATMOS 41 weather station with our ZL6 data loggers, you have the flexibility to add any of our other sensors, like soil moisture.

There's never been a thermal properties analyzer that gives accurate measurements under all conditions. Small sensors are fragile and face contact resistance. Large sensors and high-priced, steady-state methods, require long heat times, which drive moisture away from the sensor and alter the reading. Alternative instruments use one standard equation without making any adjustments for real-world conditions—plus they're bulky and expensive. There's simply been no convenient or affordable way to measure accurately. Until now.

Accurate readings at top speed

The new TEMPOS is different. We've ripped up everything in our thermal properties analyzer and reinvented it from the ground up to give you higher accuracy in much less time, at a price you can afford. How? Accurate thermal properties measurements have always been about complex mathematics. Recent scientific breakthroughs in how these complex equations are solved have enabled not only higher accuracy, but also allowed us to calibrate using significantly improved data sets—making this instrument more accurate than any other in its class. Not only that, improved proprietary algorithms enable the TEMPOS to make these measurements with an incredible one-minute read time (versus the usual 10 to 15 min).

Thermal properties analyzer takes compliance to a whole new level

The ASTM 5334- and IEEE 442-compliant TEMPOS is engineered using ISO 2008 standards. It takes accurate readings of thermal conductivity, thermal resistivity, thermal diffusivity, and specific heat in many material types across multiple disciplines, from soil and concrete to insulation, food, plastics, lubricating oil, and even human tissue. The new TR-4 needle is designed specifically to be compliant with IEEE specifications.

Each needle produces only a discrete amount of heat, virtually eliminating the moisture movement (or free convection in liquids) that could alter a reading. Short heating times mean you can use the TEMPOS thermal properties analyzer to measure frozen materials and even fluids. No other analyzer on the market can measure frozen or wet materials accurately.

The MAS-1 4-20 milliamp soil moisture sensor is the first current-based sensor to use METER’s trademark potting soils, and rockwool.

The MAS-1 delivers research-grade soil moisture accuracy at a price that makes large sensor networks economically practical. You can adequately characterize your site with sensors at multiple depths and locations, even if you’re on a tight budget.

We designed the TEROS 54 profile probe to make every step of your measurement process easier—without sacrificing accuracy or durability. Soil water content and temperature sensors are positioned at 15, 30, 45, and 60 cm depths, providing root zone measurements without requiring soil pits or cumbersome sensor retrieval at lower depths. You get the convenience of profile measurements combined with the research-grade accuracy you’ve come to expect from METER.

Avoid the cost, hassle, and time of large drilling equipment and pilot tubes. TEROS 54 installation only requires a simple 2 cm borehole for the robust quad-fin profile sensor to then be hammered into the soil. This creates better sensor/soil contact for more accurate readings. Removing the TEROS 54 is made simple with the dedicated extraction tool, making this sensor ideal for annual crops that require sensors to be installed and removed multiple times throughout the year.

The PHYTOS 31 accurately measures both the onset and duration of wetness on a simulated leaf, which in turn predicts when the onset of certain diseases or infections may occur. It’s not only a more accurate instrument, but it’s also the easiest to set up, and when paired with the ZL6 data logger, it gives you access to remote data in real time, making it a smart, simple and straightforward sensing solution.

There are several methods to measure how much light is intercepted by a canopy in order to determine if water loss is from evaporation or transpiration. There's the hard way. There's the expensive way. And then there's the smart way: the LP-80.

Rapid readings. Easy to use.

The optimal method for measuring fractional PAR (photosynthetically active radiation) is with the LP-80 Ceptometer. It's a highly accurate way to determine canopy growth and canopy light interception, along with calculating fractional interception and crop coefficient. And because the methodology is automated, it spares you from intensive hand labor, saving you time. The LP-80's low cost also saves your entire budget from evaporating.

Reliable results never get old

Backed by 35 years of research, the LP-80 is one of the most trusted and relied upon instruments among crop scientists, ecologists, and foresters for publishable data year after year. Why? It uses precise sun angle calculations to accurately and automatically calculate leaf area index (LAI) in real time, so you can be confident your data is right while in the field. And it includes external PAR sensor which can be used to make simultaneous above- and below-canopy PAR measurements as a reference for intercepted light in clear, partly cloudy, or even overcast sky conditions.

Most measurements in the soil-plant-atmosphere continuum are fairly straightforward. Measuring stomatal conductance is not. And since stomatal conductance can't be predicted from theory and must be measured, you need an instrument that's easy to use. Presenting the SC-1.

Complex science in a simplified package

Backed by solid scientific theory and 15 years of research, the SC-1 is designed to provide you with a simple solution to a complex problem. By measuring vapor flux from the leaf through the stomates, it enables you to tell the difference between transpiring leaves and ones that have shut down.
