VTSYIQI Chlorophyll Tester Meter Analyzer Non Injured Plant Leaf Chlorophyll Content Detector Testing Instrument for Measuring Instantly Relative Chlorophyll Content with Measurement Range 0.0 to 99.9 SPAD

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 or whether it is too much applied nitrogen fertilizer
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

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”, thereby learning plants’ actual demands on nitryl and helping the user identify the shortage of nitryl in soil or whether nitrogenous fertilizer has been applied excessively. This meter can be used to enhance the utilization ratio of nitrogenous fertilizer and protect the environment.
