Multifunctional Leaf Measuring Instrument for Plant Chlorophyll & Polyphenols

Price：Telephone contact
Model：IN-YL500
This multifunctional leaf measurement instrument is purpose-built for fields such as plant physiology, agronomy and horticulture, crop breeding, ecological monitoring, and nutritional or medicinal research. Integrating four core measurement functions—chlorophyll, nitrogen balance, anthocyanins, and flavonoids—it serves as a precise chlorophyll meter as well as an efficient tool for assessing nitrogen balance and measuring anthocyanin and flavonoid levels. Defined by its precision, non-destructive nature, and intelligent efficiency, it provides multi-dimensional leaf physiological data to support both research and production, making it the preferred choice to replace traditional, single-function measurement methods.

Graphic introduction

I. Equipment Overview:

This multifunctional leaf measurement instrument is tailored for fields such as plant physiology, agronomy and horticulture, crop breeding, ecological monitoring, and nutritional/medicinal research. It integrates four core measurement functions—chlorophyll, nitrogen balance, anthocyanins, and flavonoids—serving simultaneously as a precise chlorophyll meter and an efficient tool for assessing nitrogen balance, anthocyanins, and flavonoids. Defined by its "precision, non-destructive nature, intelligence, and efficiency," it provides multidimensional leaf physiological data for research and production, making it the ideal choice to replace traditional single-parameter measurement methods.

Designed for measuring vegetation leaves, the instrument enables real-time, *in-situ*, and non-destructive measurements without the need to detach samples; this preserves sample integrity and allows for long-term dynamic tracking of the same plant. It requires no complex calibration or sample preparation—simply power it on to begin measuring—significantly lowering the barrier to use. Whether in controlled laboratory environments or complex field settings like croplands and forests, the instrument operates reliably, offering greater flexibility and efficiency in leaf physiological measurements.

II. Functional Features

1. Rapid *in-vivo* plant testing supporting real-time, non-destructive measurement; allows for leaf monitoring throughout the crop growth cycle without interfering with normal growth.

2. Versatile "all-in-one" design integrating four core measurement functions: chlorophyll, anthocyanins, flavonoids, and nitrogen balance.

★3. Simultaneous measurement of all parameters in a single operation; five parameters—Total Chlorophyll (TChl), Chlorophyll a & b (Chl a, b), Anthocyanin Index (Anth), Flavonoid Index (Flav), and Nitrogen Balance Index (NBI)—are displayed and stored simultaneously on the same screen.

4. High measurement accuracy; features a built-in system to prevent interference from strong ambient light.

★5. Large storage capacity; capable of storing, viewing, and exporting 50,000 data sets.

6. Multifunctional USB interface supporting data export and charging; allows for direct connection to a PC for data export to Excel, ensuring simple and convenient operation.

7. GPS positioning function: displays real-time satellite coordinates (latitude and longitude) to pinpoint the current testing location. ★8. The instrument features a built-in 4G wireless transmission module, enabling real-time data uploading from field environments. Test results are transmitted directly to a dedicated cloud-based agricultural data center; a specific account is assigned for accessing and viewing the uploaded data.

★9. The cloud-based agricultural data center allows for historical data retrieval across custom time ranges. Users can view data such as measurement time, total chlorophyll (TChl), chlorophyll a and b, anthocyanin index (Anth), flavonoid index (Flav), nitrogen balance index (NBI), and GPS location information. The system supports online downloading, export to Excel, and printing.

10. High-contrast LCD screen ensures clear data visibility even in bright sunlight.

11. Designed with a low-power consumption mode and a built-in, high-capacity rechargeable lithium-ion battery (featuring overcharge protection), the device is energy-efficient, eco-friendly, and convenient for outdoor operation.

★10 cm leaf clip allows for easy measurement of the center of large leaves; the design is optimized for practical use, minimizing fatigue during prolonged operation. ★13. Built-in bilingual (Chinese/English) display; one-touch switching; seamless integration
