Feature

●Chlorophyll Tester can instantly measure the relative chlorophyll content (unit SPAD) or "greenness" of plants, so as to know the true nitro demand of plants and help you understand the lack of soil nitro.
●Two LED light sources emit two kinds of light, one is red light (peak wavelength is 650m), and the other is infrared light (940nm)
●The instrument is small, portable and easy to handle with one hand
●Non-destructive measurement, it can quickly and non-destructively detect plants, without damaging crop growth
●The instrument comes with 2G data storage, which is convenient for viewing observation records

Please Note That This Product ONLY can measure Chlorophyll Content !!!

Product Introduction

  • Chlorophyll plays a crucial role in the photosynthesis of plants. Its content is an important indicator of plant nutrition stress, photosynthetic capacity, and growth conditions. Chlorophyll content measurement can be used to monitor the growth and development conditions of plants, thereby making scientific guidance of cultivation, fertilization and management, ensuring the good growth vigor.
  • The chlorophyll meter is able to measure the relative content of chlorophyll in plant leaves (unit SPAD) or “greenness”.
