SpotOn Quantum PAR Light Meter
An affordable meter that provides scientifically accurate Photosynthetic Active Radiation (PAR) light readings under any light source including LED.
FEATURES:
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).
COMPACT AND EASY TO USE.
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 SOFT CARRYING CASE.

If you need extended reach for your PAR light measurements in larger grow areas or difficult-to-access locations, consider pairing your Quantum PAR Light Meter with the SpotOn Extension Wand for Quantum PAR Light Meter, which helps you take accurate light readings from higher ceilings or deep inside canopies without straining.
For users who monitor other environmental conditions alongside light levels, the Quantum PAR Light Meter is complemented well by the Light Meter for Lux & Foot-Candles with NIST Certificate of Calibration, a versatile tool that measures visible light intensity in Lux or Foot-Candles for safety, photography, and scientific applications.
If you are comparing technologies or seeking alternate measurement tools, you might also check out the Full Spectrum PAR (Photosynthetically Active Radiation) Meter, another reliable instrument designed for precise PAR readings under various lighting conditions, ideal for growers and researchers focused on maximizing plant performance.
