The future of soil moisture monitoring starts here
Get more out of every measurement with the SOLYX 14 featuring
CDX (learn about CDX). Continuously monitor dielectric
permittivity, soil temperature, bulk electrical conductivity (ECb),
volumetric water content (VWC), and pore water electrical
conductivity (ECw). Designed and proven through rigorous durability
testing, the SOLYX 14 is METER's toughest, longest-lasting sensor
yet-ensuring you get consistent, accurate soil moisture data season
after season, year after year.
Soil moisture-evolved
Accurate soil moisture measurement relies on more than just
collecting and processing data. To truly trust data validity,
sensors should be easy to consistently install correctly and
durable enough to endure years of use in harsh environmental
conditions. METER instruments are chosen by scientists, growers,
and engineers worldwide for their accuracy, and the CDX technology
behind the SOLYX 14 marks the next advancement in soil moisture
measurement.
Redefining what's possible with CDX technology
Developed by METER scientists, Complex Dielectric through
intersection, or CDX, is a patented impedance technology that makes
accurate measurement of VWC, EC, and soil temperature possible in
soil, substrates, and porous material across a wide range of
salinities and temperatures.
By measuring complex dielectric permittivity, the SOLYX 14
independently measures both the real dielectric permittivity
(related to water content) and the imaginary dielectric
permittivity (which is influenced by salts and lossy clays). That
means you can achieve accurate soil moisture measurements in more
places than ever before.
Consistent installation = higher accuracy
The more consistent the sensor installation, the more reliable
the data. That's why the SOLYX 14 can be installed using the same
Borehole Installation Tool (TBIT) as the TEROS soil moisture
sensors, which minimizes air pockets and ensures solid
sensor-to-soil contact. The TBIT firmly inserts the sensor into the
side of a 10 cm borehole at depths of up to 5 meters, making
installation quicker, easier, and more accurate. Once installed,
setup is as simple as plug-and-play with METER data loggers,
sending real-time data to ZENTRA Cloud for remote data
visualization, computation, and collaboration.
Engineered for endurance
Whether you're measuring soil moisture over a season or a
decade, SOLYX 14 delivers long-term stability and reliability. Its
low-power requirements make it ideal for permanent
installation-even at remote sites. Robust stainless-steel needles,
a high-durability cable, and epoxy fill enable this sensor to
provide research-grade accuracy year after year, even under harsh
conditions. We're so confident about the long life of the SOLYX 14,
we've increased our standard warranty from one to three years.
