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
12 soil moisture, temperature, and EC sensor.
Better accuracy-verified
The TEROS 12 soil moisture sensor 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 12 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 soil moisture sensor lets you think bigger
The TEROS 12 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 TEROS 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 12 is plug and play with the cloud-connected ZL6
logger. No programming required. See your data instantly in real
time, wherever you are.
With you for the long haul-guaranteed
The most recent addition to our TEROS water content line, the
plug-and-play TEROS 12 soil moisture, temperature, and electrical
conductivity sensor 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 12
soil moisture sensor 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 12.
