SM150T Soil Moisture Sensor
The SM150T’s advanced patented electronics and tough build produce a highly reliable soil moisture sensor with exceptional salinity and temperature stability. The SM150T is engineered to withstand long term burial – the sensor, connectors and cable are all environmentally protected to IP68. It offers moisture accuracy of ± 3% (after soil specific calibration) and the built in temperature sensor achieves ± 0.5°C.
・Dependable ±0.03m3/m3 (± 3% F.S) soil moisture accuracy
・ADR method that is not affected by temperature and salinity (nutrient) fluctuations
・Applicable to other applications such as manual spot measurement and fixed point measurement with logger
・Suitable for -20 to +60°C environments (for research on irrigation, greening, hydrology, and global warming countermeasures)
・DC input range 5~14VDC for driving sensors. Output range 0~1.0VDC
・All products have been calibrated, so there is no individual difference when purchasing multiple products within the accuracy guarantee.
・Built-in thermistor temperature sensor
The SM150 Soil Moisture Kit provides an affordable and easy-to-use tool for obtaining reliable moisture measurements with minimal soil or substrate disturbance.
The kit comprises an SM150T* Soil Moisture Sensor, a dedicated HH150 Moisture Meter and a carry case. The cable and connector are watertight – an essential requirement for potentially wet environments.
The HH150 Meter displays volumetric water content (% volume). Please note that although the SM150T Sensor has a built-in temperature sensor, the HH150 Moisture Meter does not measure or display temperature
|HH150: SM150 KIT 付属品||Handy Logger HH2|
|The HH150 is a display unit for direct reading only and data cannot be saved to a PC, etc. It is easy to operate and can be used by anyone. It is recommended for measurement while carrying.||Some people may find it inconvenient just to display it as a KIT accessory HH150.For those who want to save data while carrying it around, we recommend combining it with the Handy Logger HH2.|
Simultaneous measurement of soil moisture and soil temperature at multiple points
Some customers may want to simultaneously measure soil moisture and soil temperature with the SM150T. For those people, we recommend multi-channel data loggers.
