Quantum PAR Light Meter | SpectrumTechnologies

The Quantum PAR Light Meter provides scientifically accurate PAR light readings under any light source, including LED. It is designed for both indoor and outdoor use, making it versatile for various applications.

Features

• Provides accurate PAR light readings from any light source:
  • Full sun to full shade indoors or outdoors.
  • Light sources (LED, High Pressure Sodium, Metal Halide, Florescent, Halogen).
• Three modes of operation:
  • Instant Spot Measurement mode for PAR light readings.
  • Scan mode for quickly averaging PAR over an area.
  • DLI mode shows Daily Light Integral on the LCD (no computer needed).
• Water and impact resistant.
• Integral mounting plate for: stand, stake, lanyard & hanger hole, and magnet mounts.
• 1/4-20 threaded hole for mounting on camera tripods and stands.
• Includes a sensor cover and carrying case.
