Zimmermann Irrigation Monitoring
•
non-invasive, Internet-based sensor
technology
•
continuously measurements of plant
water status (turgor pressure) with high
precision in real time under field
conditions
The ZIM-probe measures turgor pressure
How well plants are being supplied with water can be viewed by the
innovative magnetic probe that is simply clamped to the leaves
The ZIM-probe measures turgor pressure
