PlantPen NDVI 310

Key Features and Benefits

• Chlorophyll Content Measurement: The device measures the Normalized Difference Vegetation Index (NDVI), a crucial index calculated from the difference in leaf reflectance between the near-infrared (NIR) and visible (VIS/Red) light spectrum.2 The formula used is:
  NDVI = {R_{NIR} – R_{RED}}/{R_{NIR} + R_{RED}}

  This index is directly related to the plant’s photosynthetic capacity and is an excellent indicator of relative chlorophyll content.

• Non-Destructive Design: Utilizing a mechanical leaf-clip and an internal dual-wavelength light source (typically RED approx. 635 nm and NIR approx 760 nm), the PlantPen measures attached or detached leaves without damage.

• Integrated GPS Module: A built-in, ultra-high-sensitivity GPS module provides accurate spatial coordinates for every measurement (accuracy<=1.5  m), allowing for precise mapping and localization of data points.

• Field-Ready Portability: With a weight of only 188 g and a compact size (135 x 65 x 33  mm), along with a long-lasting Li-ion rechargeable battery (up to 70 hours of typical operation), it is ideal for extensive fieldwork.

• Data Management & Analysis:

  • Internal memory can store up to 100,000 measurements.

  • Data transfer is achieved via USB or Bluetooth communication.

  • The included FluorPen software (compatible with Windows 7 and higher) provides comprehensive routines for data visualization, analysis, graphing, and export to Microsoft Excel, including GPS mapping functionality.

Ideal Applications

The PlantPen NDVI 310 is a versatile tool perfect for:

• Agronomy & Forestry: Monitoring crop nitrogen status, irrigation needs, and forest health.

• Plant Biology & Screening: Rapidly assessing the vigor of different plant varieties or mutants.

• Photosynthesis Research & Education: Studying the effects of stress (e.g., water, nutrient deficiency) on photosynthetic efficiency.

• Stress Physiology: Detecting early signs of plant stress based on changes in leaf chlorophyll.

The PSI PlantPen NDVI 310 is the preferred choice for researchers and agricultural professionals seeking a convenient, accurate, and cost-effective method to monitor plant photosynthetic pigment content and vitality in real-time.
