SpotOn Quantum PAR Meter

The SpotOn Quantum PAR Meter is an affordable meter that provides scientifically accurate Photosynthetic Active Radiation (PAR) light readings under any light source including LED!

SpotOn Quantum PAR Meter highlights:

Provides accurate PAR light readings from any light source:

• Full sun to full shade indoors or outdoors.
• Artificial 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).

SpotOn Quantum PAR Meter features:

• Compact and easy to use.
• Water and impact resistant.
• Integral mounting plate for stand, stake, magnet mounts and lanyard and hangar hole.
• 1/4-20 threaded hole for mounting on camera tripods and stands.
• Includes a sensor cover and soft carrying case.
