KONICA MINOLTA CHLOROPHYLL METER SPAD-50PLUS

Konica Minolta SPAD-502Plus is a tool for non-destructive measurement of leaf.

The SPAD-502Plus enables fast and easy measurement of chlorophyll content of plant leaves without damaging the leaf. It is designed to help users improve crop quality and increase crop yield by providing an indication of the amount of  chlorophyll present in plant leaves. The chlorophyll content of plant leaves is related to the condition of the plant and thus can be used to determine when additional fertilizer is necessary. Chlorophyll content is one indication of plant health and can be used to optimize the timing and quantity of applying additional fertilizer to provide larger crop yields of higher quality with lower environmental load.

The SPAD-502Plus determines the relative amount of chlorophyll present by measuring the abosrbance of the leaf in two wavelength.

The SPAD-502Plus serves in a wide variety of plant applications. Through its history, the SPAD series has established itself as a leading brand in chlorophyll measurement across the world. IT has bee serving reasearchers and growers, enabling them to perform field tests quickly and easily.

The SPAD-502Plus is lightweight and splash proof design makes it ideal for measurement in the field.
