Description 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. QUANTUM PAR LIGHT METER SPECS: Range: PAR LIGHT:0.0 to 6,500 μmol m-2 s-1DLI (Daily Light Integral):0.0 to 560.0 moles m-2 day-1 Display Resolution: PAR Light:0.1 μmol m-2 s-1 from 0.0 to 99.91 μmol m-2 s-1 from 100 to 6,500DLI:0.1 moles m-2 day-1 Accuracy: +/- 5% (each meter is calibrated to a NIST traceable light sensor on a broad-spectrum light source) Azimuth Error: +/- 1% over 360° Daily Light Integral (DLI): Calculated continuously from light readings every 3 minutes Water Resistant: IP-65 rated for use in rain, irrigation, and condensing environments (do not submerge) Operating Environment: 32-130°F(0-55°C) with 0-100% RH condensing ok Battery: CR2032 3v coin cell lithium included (2-year battery life) Size & Weight: 1.75in(4.5cm)W x 5.75in(14.6cm)L x .85in(1.8cm)D0.17lb(77g) Response Data: Spectral Response Cosine Response
