NEED BETTER ACCURACY?
METER’s soil moisture sensors do an excellent job of predicting accurate water
content in most soils, but there are some soils (i.e., very sandy soils or
heavy clays) that may require a better calibration to get the most accurate
water content value.
A soil-specific calibration may also help those who are working at the extreme
edge of the measurement range. A custom calibration for your exact soil type
can improve accuracy from the typical 3% (with the factory calibration) to 1%.
TAILORED EXACTLY TO YOUR NEEDS
When ordering the calibration service, you’ll receive the packaging to send
METER about four liters of soil. Allowing it to air dry before sending will
reduce shipping costs. After receiving the sample, our scientists will start
the calibration process as soon as the soil is dry enough. They’ll carefully
pack the soil into a container with a known volume and take a volumetric
water content measurement with the same type of sensor you’ll be using in the
field. Then they’ll place the sample into a large container and soak the soil
with enough water to raise the water content 7%.
Once it’s well mixed, they’ll repack it and take another volumetric water
content measurement. This process will be repeated until the sample is close
to saturation.
Afterward, the scientists will combine the raw sensor output data with the
known water content data to produce a calibration equation that can be easily
inserted into your software for a soil-specific calibration. In about two
weeks (four for international or non-typical soils), you’ll receive a
calibration equation tailored exactly to your soil type.
BE CONFIDENT IN YOUR DATA
Our standard soil moisture sensor calibration is good for most situations, but
if your soil is not typical, a custom soil calibration can give you complete
confidence that you’re getting the best, most accurate data in the field.
