Application: The WET150 Soil Moisture, Temperature & Electrical Conductivity Meter is a portable measurement device used to simultaneously measure three key indicators affecting plant growth: moisture, temperature, and electrical conductivity (EC) in soil or substrate. It is suitable for researchers who need to assess water and salt conditions in soil and substrate.
Features:
- Rapid measurement, requires only 5 seconds per measurement
- High accuracy for three parameters (soil moisture, temperature, electrical conductivity)
- Simple and convenient operation
- Accurate monitoring of growing conditions
- Direct measurement in the root zone
- Detachable and expandable cable system
