  • Testing area: 2mm*2mm
  • Manual measurement pattern

Share the product



The plant nutrient analyzer simultaneously saves three parameters (chlorophyll, nitrogen content and leaf temperature) at the same time. Plant chlorophyll, nitrogen content and leaf temperature are important basis for plant fertilization and irrigation. NIR spectroscopy can be used to detect leaf chlorophyll, nitrogen and leaf temperature non-destructively.


  1. Save chlorophyll, nitrogen and leaf temperature data at the same time, which is convenient for drawing plant map nutrients, leaf temperature, etc., and accurately irrigating and fertilizing plants.
  2. Fastand non-destructive testing of plants, without affecting plant growth.
  3. Rapid determination: Test plant chlorophyll, nitrogen and leaf temperature at the same time.
  4. Manual measurement pattern.
  5. View the data stored in the past and display three parameters at the same time.
  6. The computer can transmit wired or wireless data for easy management and analysis.
  7. Withthe characteristics of convenient data storage, direct display of stored data, and low power consumption.
