The Phyto-NMR sensor is a portable NMR device that employs basic relaxometry to non-invasively measure the amount of liquids in fruits, stems or leaves.

The sensor is suitable for use in the greenhouse and the lab. It is typically used to monitor growth dynamics of plant parts in response to environmental conditions such as drought, salt, or changes in evapotranspiration.

The typical time resolution is around 5 minutes per time point, but can be reduced to a few seconds as well.
