Chlorophyll meter SPAD 502 Plus

About This Instrument

<p>Cholorophyll meter can be used to determine the amount of chlorophyll present in plant leaves. The amount of chlorophyll present in plant leaves can serve as an indicatorof the everoll condition of the plant itself.</p> <p>The SPAD value determined by the SPAD-502Plus provides an indication of the relative amount of chlorophyll present in plant leaves.</p>
