Product Description
Chlorophyll Meter
The chlorophyll meter (or SPAD meter) is a simple, portable diagnostic tool that measures the greenness or relative chlorophyll content of leaves.
Readings are given in soil plant analysis development (SPAD)values that indicate relative chlorophyll content. SPAD values have strong linear relationships with weight or thickness or area based nitrogen concentration. The linear relationship between nitrogen and SPAD values has led to the adaptation of the SPAD meter to assess crop N status and to determine the plants need for additional N fertilizer. A non invasive meter.
SPAD 502 measures the greenness straight off the leaves. Compared to traditional destructive methods, the use of this equipment saves time, space and resources The SPAD 502 is used in many crops to diagnose the integrity of photosynthesis, predicting nitrogen status, maximize yield and fertilizer management. From cultivation to harvest, SPAD are used for crops and fertilizer management.

FAQs of Chlorophyll Meter:
Q: How is the Chlorophyll Meter with GPS used for plant analysis?
A: To use the meter, first obtain a blank reading in measurement mode, then clamp it onto a leaf to measure chlorophyll concentration. The precise results help determine nutrient status, evaluate plant stress, and inform fertilizer and harvest decisions.
Q: What benefits does the GPS function provide in chlorophyll measurements?
A: The GPS integration geo-tags every reading, enabling users to track and map the exact locations of measurements. This is particularly valuable for large fields, as it aids in pinpointing areas that require attention or further analysis.
Q: Where can this Chlorophyll Meter be applied effectively?
A: This device is best suited for industrial agricultural settings, research fields, and large-scale crop testing. It supports exporters, manufacturers, and suppliers needing accurate plant health evaluation across diverse locations in India and beyond.
Q: What is the process for data storage and retrieval on the meter?
A: The meter automatically logs each measurement in its 16GB memory, supporting up to 160,000 data points. Data can be easily transferred to a computer using the included USB cable for further analysis or record-keeping.
Q: When should chlorophyll concentration be measured for optimal results?
A: Measurements are generally most beneficial during key growth stages, particularly when evaluating nutrient status, identifying plant stress, or optimizing the timing of fertilizer applications and harvests.
Q: What is included in the Chlorophyll Meter package?
A: The package contains the chlorophyll meter with GPS, a rechargeable battery, necessary connectors, a USB cable for data transfer, and a comprehensive user manual to assist with operation and maintenance.
