The SM150T measures soil moisture and temperature with research‐grade accuracy
· Research grade sensor at a great price
· Soil moisture and temperature
· Dependable moisture accuracy ± 3%
· Robust and buriable.
Research grade sensor
Patented sensor electronics produce a highly dependable sensor with exceptional salinity and temperature stability. The SM150T is built to withstand long term burial ‐ the sensor,connectors and cable are all environmentally protected to IP68.Moisture accuracy is 3% (after soil specific calibration) and the built-in temperature sensor achieves 0.5°C accuracy.
Data logging and readout
The SM150T is a dual purpose probe ‐ it can be used portably for instant moisture readings, or left installed in the soil for continuous logging ‐ to provide moisture and temperature data. For installed sensors ‐ The SM150T can be logged by any Delta data logger and by many loggers from other manufacturers (simple 01 V output). For portable applications ‐ The SM150T is available as the convenient SM150 Kit, complete with carry case and HH150 readout meter* (NB: the HH150 does not provide temperature indication from the SM150T Sensor). Please see overleaf for more about SM150 Kits.
