Chlorophyll Meter SPAD

Chlorophyll Meter SPAD

The SPAD Chlorophyll Meter instantly measures chlorophyll content or greenness of your plants to reduce the risk of yield limiting deficiencies or costly overfertilizing. The SPAD 502 Plus quantifies subtle changes or trends in plant health long before they are visible to the human eye. Non-invasive measurement; simply clamp the meter over leafy tissue, and receive an indexed chlorophyll content reading (minus9.9 to 199.9) in less than 2 seconds. Assess nitrogen needs by comparing in field SPAD readings to university guidelines or to adequately fertilized reference strips. Research shows a strong correlation between SPAD measurements and leaf N
