“​​One of the extraordinary things about working with (METER) was the extent to which they were receptive to a challenge. I could say, we're trying to figure out how we interpret permittivity data in a pathologically dry soil. And a week later, a model would come back...the response was—we know how to do that.

The all-new TEROS 12 soil moisture sensor delivers an excellent price-to-performance ratio in a device that is easy to use and includes electrical conductivity.
  • Long-life soil moisture, temperature, and EC sensor
  • Increased volume of influence (1010 mL)
  • Robust, epoxy body for tough field conditions


We designed the TEROS 54 soil moisture profile probe to make every step of your measurement process easier—without sacrificing accuracy or durability.
  • Multi-depth profile probe measures water content and temperature
  • Easy plug-and-play operation
  • See all your data remotely in real-time


At METER, we think getting your data shouldn’t be complicated or costly. And we think wireless should actually be wireless. That’s why we made the ATMOS 41W.

  • A true wireless weather station ideal for long-term, remote installations
  • Incredible 10-minute installation time
  • Completely solar powered


The world's best all-in-one weather station for atmospheric measurements that doesn't limit you with other sensors.
  • Measures 12 weather variables
  • Designed for continuous deployment in harsh climates
  • Connect to ZL6 for data capture and management


The ATMOS 14 will rapidly and reliably measure air temperature, relative humidity, barometric pressure, and vapor pressure, making benchmarking quick and hassle free.
  • Four measurements in one sensor
  • Collect data remotely when used with the ZL6 data logger
  • Fast response
