Product Overview
Measurements are taken by just closing the measuring head on the leaf. Since the leaf is not cut off or damaged in any other way, the same leaf can be measured as the plant grows.

Up to 30 measurements can be stored in memory and displayed on a trend graph, so that changes in measurements over time can be seen and abnormal values can be noticed at a glance.<br
