​Portable Chlorophyll Meter

Application:
Chlorophyll Meter is able to measure chlorophyll content of plants and leaf temperature. Chlorophyll content and leaf nitrogen content have a very close relationship. Thus, chlorophyll content can reflect plants demand for nitro. Using the instrument can put nitrogen fertilizer reasonably, improve utilization of nitrogen and protect environment.
Features:
  • Enter the name of the plant, the standard nitrogen content and utilization, the standard fertilizer can be directly calculated.
  • Chlorophyll, leaf temperature is displayed on same screen at the same time, and can be stored at the same time.
  • USB interface can be connected to the computer to export the measured data, to facilitate the management and analysis of plant nutrients. (Only for CM-B).
