STR-4N Plant nutrition tester
The instrument is compact and easy to operate with one hand.
The chlorophyll, nitrogen, leaf temperature and leaf humidity of plants can be determined simultaneously
Non - destructive measurement, can be quickly non - destructive in vivo plant testing, do not damage crop growth.
After an unexpected power failure, the data inside the host will not be lost if it has not been saved.
Historical data can be viewed, deleted item by item or deleted with one click.
Reasonable power management scheme, built-in rechargeable lithium battery, instrument with backlight function.
The device is equipped with USB interface, which can be connected to the computer to export the measured data, so as to facilitate the management and analysis of plant nutrients.
Plant name, standard nitrogen content and utilization rate can be input to directly calculate the amount of fertilizer applied.
