Product Description SPAD-502Plus Konica Minolta Waterproof Handheld Digital Chlorophyll Meter Plant Tester Analyzer Features:Quick, easy measurement of chlorophyll levels in plant leaves without damaging the leafMeasurements are taken by just closing the measuring head on the leaf.Since the leaf is not cut off or damaged in any other way, the same leaf can be measured as the plant grows. Trend graph displayUp to 30 measurements can be stored in memory and displayed on a trend graph, so that changes in measurements over time can be seen and abnormal values can be noticed at a glance. Water-resistantThe SPAD-502Plus is water-resistant (IPX-4) so it can be used outdoors even in the rain. It is not immersible, and should not be washed with water. Compact and lightweight for portabilityThe SPAD-502Plus is small enough to fit in a pocket and weighs only 200g, so it can be taken anywhere. Low power consumptionThe SPAD-502Plus uses LED light sources, resulting in extremely low power consumption, with approximately 20,000 measurements from one set of fresh alkaline-manganese batteries. Monitoring of growth and health of plantsThe SPAD-502Plus can be used to monitor the growth and health status of a wide variety of agricultural products, including wheat, rice, corn, cotton, etc. Nitrogen fertilization optimizationThe SPAD-502Plus can be used for determining when and how much nitrogen fertilizer should be provided to plants. Optimizing fertilization in this way leads to not only greater yields of higher quality, but also results in less over-fertilization, reducing environmental contamination due to the leaching of excess fertilizer into the soil and underground water.
