Product Introduction

▷The chlorophyll meter is able to measure the relative content of chlorophyll in plant leaves (unit SPAD) or “greenness”, thereby learning plants’ actual demands on nitryl and helping the user identify the shortage of nitryl in soil or whether nitrogenous fertilizer has been applied excessively. This meter can be used to enhance the utilization ratio of nitrogenous fertilizer and protect the environment.
