Performs quick measurements of the chlorophyll content of leaves without damaging the leaf. Its lightweight, splashproof design make it ideal for measurements in the field.

This model enables quick, easy measurement of the chlorophyll content of plant leaves without damaging the leaf. Chlorophyll content is one indicator of plant health, and can be used to optimize the timing and quantity of applying additional fertilizer to provide larger crop yields of higher quality with lower environmental load.

The SPAD-502Plus can be used to monitor the growth and health status of a wide variety of agricultural products, including wheat, rice, corn, cotton and so.

  • Compact and lightweight for portability: The SPAD-502Plus is small enough to fit in a pocket and weighs only 200g, so it can be taken anywhere.
  • Water-resistant: The SPAD-502Plus is water-resistant (IPX-4) so it can be used outdoors even in the rain. It is not immersible so please do not wash it with water.
  • Low power consumption: The SPAD-502Plus uses LED light sources, resulting in extremely low power consumption, with approximately 20, 000 measurements from one set of fresh batteries.
  • Trend graph display: Up 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.
  • No damage to the Leaf: Quick, easy measurement of chlorophyll levels in plant leaves without damaging the leaf. Measurements 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.
  • Nitrogen fertilization optimization: The 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.
