An affordable yet highly precise meter that provides scientifically accurate Photosynthetic Active Radiation (PAR) light readings under any light source including LED! (Wand available as a separate purchase).
Research-grade quantum PAR measurement by Innoquest.
Accurate PPFD 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 acts as a stand, or can be used as a stake. Also includes lanyard or hanger hole for suspending the meter, and magnet mounts.
1/4-20 threaded hole for mounting on tripod or extension wands, selfie sticks.
Includes and sensor cover and soft carry pouch.
