Research Grade Accuracy
Like other soil moisture sensors, the SAM measures soil
moisture accurately without the sensitivity to electrical conductivity
and variation in soil types that have plagued inexpensive sensors in the
past.
The SAM delivers research-grade accuracy at a
price that makes large sensor networks economically practical. You can
adequately characterize your site with sensors at multiple depths and
locations, even if you're on a tight budget. And the SAM's ultra-long
cable lengths give you even more flexibility to put your sensors where
you want them.
Engineered for Accuracy
The SAM-01 determines volumetric water content (VWC ) by measuring
the dielectric constant of the media using capacitance/frequency domain
technology. The sensor uses a 70 MHz frequency, which minimizes salinity
and textural effects, making the SAM accurate in almost any soil or
soil-less media. Factory calibrations are included for mineral soils,
potting soils, and rockwool. |
