Spad 502 Plus Chlorophyll Fluorometer

The SPAD‑502Plus is a handheld, non‑destructive chlorophyll meter that enables rapid measurement of the chlorophyll content of plant leaves. By simply clamping the device’s measuring head onto a leaf, the meter provides a SPAD value that correlates to chlorophyll levels (and indirectly, the plant’s nitrogen status). This insight helps agronomists, farm‑managers and researchers optimize fertilizer usage, monitor plant health and enhance crop yield and quality.

Its compact, water‑resistant (IPX‑4) form factor and extremely low power consumption make it well‑suited for field use across a wide variety of crops including wheat, rice, corn, cotton and more.
