You need sensor longevity
Soil can be highly variable in space, requiring many
measurements and frustrating amounts of your research dollars. Not
to mention the extra cost and hassle of replacement sensors if you
need long-term data. Make large sensor networks simpler,
longer-lasting, and more affordable with the ultra-dependable TEROS
11 soil moisture and temperature sensor.
Better accuracy-verified
The TEROS 11 uses a completely new calibration procedure that
maximizes accuracy and minimizes sensor-to-sensor variability while
keeping the cost reasonable. So you can be confident that every
sensor you install is going to read exactly like the next one.
Unlike other sensors on the market which spec an unverifiable ±1.0%
VWC accuracy, the TEROS 11 was rigorously tested by our soil
physicists across a challenging range of soil types and EC levels
so you can be confident in the accuracy of your data.
Plus, TEROS sensor repeatability can be checked with an accuracy
verification standard. No other soil moisture sensor has this
ability. Just slide the verification clip onto a sensor and plug it
into a logger. If it reads within the right range, your sensor is
good to go.
Small sensor lets you think bigger
The TEROS 11 volumetric soil moisture sensor delivers the best
volume of influence to sensor size on the market so you're less
susceptible to soil variability errors. We've optimized the
circuitry in this 9.4-cm sensor to deliver an incredible one-liter
volume of influence (versus the 200 mL typical for most sensors).
Most soil sensors that measure this much volume are 20 cm or
longer, causing installation headaches. Not only that, you can cut
your installation time in half or more when you install with the
new Borehole Installation tool. The tool mistake-proofs
installation, eliminating common errors that cause uncertainty in
the data-like air gaps, or preferential flow. And the TEROS 11 is
plug and play with the cloud-connected ZL6 logger. No programming
required. See your data instantly in real time, wherever you
are.
Unbeatable price to performance ratio
Soil can be highly variable in space, requiring many
measurements and frustrating amounts of your research dollars. Not
to mention the extra cost and hassle of replacement sensors if you
need long-term data. Make large sensor networks simpler,
longer-lasting, and more affordable with the ultra-dependable TEROS
11 soil moisture and temperature sensor.
With you for the long haul-guaranteed
The culmination of our new TEROS water content line, the
plug-and-play TEROS 11 makes your life easier with a large volume
of influence, reduced sensor-to-sensor variability, and a
near-bulletproof form factor-which lasts up to 10 years in the
field. These innovations, along with our well-published capacitance
technology, an accuracy verification standard, real-time, remote
data visualization with ZENTRA Cloud, and a blazing fast
installation tool have combined to generate our most accurate,
easy-to-use, highly durable-yet still economical-soil moisture
sensor. We're so confident about the long life of our TEROS 10, 11,
and 12 sensor line, we've increased our standard warranty from one
to three years.
Legendary technology-long-lasting performance
Backed by over 20 years of soil moisture research, the TEROS 11
combines METER's well-tested 70 MHz circuitry with an extremely
ruggedized epoxy fill and securely attached, sharpened stainless
steel needles that easily slip into the soil and are resistant to
salts, so you can worry less about sensor deterioration. Very low
power consumption and a high resolution provide increased precision
over a longer period of time. If you're planning a long-term large
sensor network and want long-lasting performance for less work and
less of your research budget, then choose the TEROS 11.
