Ideal for horticulture, agriculture, and environmental monitoring, this meter provides essential data for optimizing plant growth and light management.

Key Features:

• Accurate PAR Measurements: Measures PAR light levels from 0.0 to 6,500 μmol m⁻² s⁻¹ under any light source, indoors or outdoors.

• Three Operating Modes:

  • Instant Spot Measurement: For real-time PAR readings.

  • Scan Mode: Averages PAR light levels over an area.

  • DLI Mode: Calculates Daily Light Integral (DLI) directly on the LCD display.

• Durable Design: Water and impact-resistant with an IP-65 rating, suitable for use in rain, irrigation, and condensing environments.

• Versatile Mounting Options: Includes a 1/4-20 threaded hole for tripods, stands, and other mounting accessories.

• Compact and Portable: Lightweight and easy to use, with a soft carrying case and sensor cover included.

Applications:

• Monitoring PAR levels for optimal plant growth in greenhouses, grow rooms, and outdoor settings.

• Evaluating light distribution and intensity for horticultural and agricultural applications.

• Calculating Daily Light Integral (DLI) to ensure plants receive adequate light for photosynthesis.
