SPAD-502Plus Chlorophyll Meter Plant Chlorophyll Content Tester Plant Nutrition Tester High-Precision Detection of Chlorophyll and nitrogen Content, Fast Measurement, Data Storage and Analysis

The SPAD-502PLUS Chlorophyll Meter instantly measures the relative chlorophyll content or "greenness" of your plants. This gives you an idea of your plants' true nitrogen needs and helps you know if your soil is deficient in nitrogen or if you are applying too much nitrogen fertilizer. With this instrument, you can improve the efficiency of your nitrogen fertilizer application. An instrument that helps users understand the nutritional status of crops by measuring the chlorophyll content of crop leaves. The chlorophyll content is related to the growing conditions of the crop, so you can determine if you need to add the proper fertilizer. By optimizing nutritional conditions, healthier crops can be grown, resulting in a high quality harvest. Measurements are made by simply inserting a leaf and then turning off the measuring probe without cutting the leaf off, allowing specific leaves to be monitored throughout the growth of the crop, allowing results to be analyzed in a more scientific manner.

• 【Trend graph display】 the measured trend of multiple sets of data will be displayed in the graph, those data with large differences can be found at a glance, so as to get attention and analysis.
• 【 lightweight, easy to carry】SPAD-502PLUS has a small body, only 200g weight, can be easily put into the pocket and take to the site for measurement.
• 【Measurement is quick and easy】Measurement can be done simply by inserting and closing the measuring probe into the leaf, without cutting the leaf off, so that specific leaves can be monitored throughout the growth process of the crop, thus obtaining more scientific analysis results.
• 【low battery consumption】SPAD-502PLUS uses LED lighting, so it can greatly reduce battery consumption, a set of 2 AA batteries, can be measured about 20,000 times.
• 【the measurement area is small】 the actual measurement area is only 2 x 3mm, even if it is a very small blade, can also be measured. In addition, the depth adjustment device can make even the smallest blade accurately positioned for measurement.
