260-RK300-04 Leaf Wetness Sensor

260-RK300-04 Leaf Wetness Sensor
260-RK300-04 Leaf Wetness Sensor
The 260-RK300-04 Leaf Wetness Sensor is a useful tool for monitoring leaf wetness. The sensor provides accurate measurement of trace moisture, fog, mist, frost, and ice crystal residue.
Product Details

The 260-RK300-04 Leaf Wetness Sensor is a useful tool for monitoring leaf wetness, an important factor in calculating irrigation requirements and in preventing pests and disease. The shape of the sensor blade simulates the characteristics of the leaf surface. By measuring the variation of the dielectric constant of the upper surface of the blade, the sensor provides accurate measurement of trace moisture, fog, mist, frost, and ice crystal residue.

Features

  • Emulates water accumulation on the leaf
  • Detects fog, condensation, frost, and rainfall
  • IP65 rated waterproof sensor
  • High precision, fast response, reliable performance
  • Multiple signal output options are available

Applications

  • Research on the growth and development of crops
  • Early warning of pests and disease potential
  • Irrigation and sprinkler monitoring

Mounting

  • Install the sensor with the upper surface of the blade at an angle similar to that of a natural leaf.
