Weiber-0090-502
The Weiber Chlorophyll Meter instantly measures chlorophyll content or "greenness" of your plants to reduce the risk of yield-limiting deficiencies or costly over fertilizing. The Weiber-SPAD-0090 502 Plus quantifies subtle changes or trends in plant health long before they're visible to the human eye. Non-invasive measurement; simply clamp the meter over leafy tissue, and receive an indexed chlorophyll content reading (0-99.9) in less than 2 seconds. Assess nitrogen needs by comparing in-field Weiber-SPAD-0090 readings to university guidelines or to adequately fertilized reference strips. Research shows a strong correlation between Weiber-SPAD -0090 measurements and leaf N content.

USAGE: Our Chlorophyll meter can instantly measure the relative content of chlorophyll of plants, or "green level", the chlorophyll content of plant leaves indicates the plant's own conditions, the leaves of plants are growing well will contain more chlorophyll, chlorophyll content and leaf nitrogen in There is a close relationship between content and therefore measured values of chlorophyll, it also shows the true plant nitro-demand, through this instrument it is easy to calibrate the dose of
fertilizer to improve nitrogen utilization and
protection of the environment (prevention of excessive nitrogen fertilizer causing water pollution)
