As a leader in soil monitoring instrumentation, Stevens offers portable and in-situ sensors to measure moisture, EC (salinity), temperature and matric potential.
Moisture, EC and Temperature - In-Situ
RELIABLE: Continual, long-term data without calibration.
RUGGED: Durable stainless steel tines, fully potted components, compact sealed design and a 5-year warranty.
SIMPLE: Set it and forget it.
ACCURATE: Consistent research-grade accuracy every season, every location.
Moisture and Temperature - Profiling
Stevens Gropoint Profile
Unlike any other soil profiling probe, GroPoint Profile provides true soil profiling quantification, measuring the average moisture across the entire length of each segment. This unique feature allows measuring the water movement through the soil continuously, rather than just at discrete positions on the probe.
Because the TensioMark bases its measurements on the thermal properties of the soil, it does not need to be calibrated by the user, does not need to be filled with water, has excellent accuracy and stability, and a much larger range than any conventional tensiometer.
It features fully-potted components, robust PVC Type II housing, plus a durable 316 grade stainless steel tine for easy soil insertion.
