Sensors for PTM-48A and PM-11
Overview
- RTH-11 Meter (for PM-11) Photosynthetic radiation, Air Temperature and Humidity.
- RTH-48 Meter (for PTM-48A) is similar to RTH-11 but has additional Leaf wetness sensor. This sensor is used for switching air pump off in wet conditions in order to prevent water ingress in the gas measurement system.
- SMTE Soil Moisture, Temperature and EC sensor, witch fits both PM-11 and PTM-48A.
- All sensors have standard calibration which is preset in the data logger software.
