Plant Stem Moisture Content Probe MIJ-16
Feature
- ・Easy to insert needle part at exact position and depth
- ・Measure several positions with only one probe
- ・Needle and probe can be connected for continuous monitoring.
Overview
The parameter that represent water movement involves plants are evaporation rate, Leaf water potential, soil water potential, or environmental reason. Purpose of MIJ-16 is that to measure volume water content in the tree. Many researchers tried to customize TDR or ADR sensors to measure the volume water content in the tree; but there are two major issues that it is hard to insert the metal rod into the tree or hard to contact the inserted metal rod electronically. To avoid these issues and let it measure easily, MIJ-16 used reliable Delta-T ML3 for the customized base.
Installation and usage:
- ・To insert needle part at exact position and depth by using tool for MIJ-16
- ・For continuous monitoring. 1.3mm socket set screws to connect probe and needle.
- ・For portable purpose we suggest use HH2 reading logger and for continuous measurment we suggest waterproof logger such asMIJ-12.
