PHOTOBIO Advanced Quantum PAR Meter for Accurate PAR Readings
The PHOTOBIO Advanced Quantum PAR Meter is a professional-grade PAR light meter designed to measure photosynthetically active radiation (PAR) from 400 to 700 nm, giving you true micromole readings where it matters most for plant growth. Its highly accurate remote quantum sensor connects to the handheld meter via included coiled and straight cables, allowing you to measure PPFD exactly where your canopy is. With simple, intuitive controls and a clear display, this PAR meter is ideal for dialing in LED fixtures, tuning light distribution, and benchmarking different lighting setups in grow rooms, greenhouses, and controlled environment agriculture.
Quantum PAR Meter Designed for Professional Growers
Built for working growers, the PHOTOBIO Advanced Quantum PAR Meter is powered by easy-to-replace AAA batteries and stores up to 99 readings, so you can log measurements across multiple zones, benches, or rooms without losing data. The rugged remote sensor lets you quickly map hot spots and dark zones, helping you adjust fixture height, spacing, and dimming to achieve uniform PPFD at the canopy. By accurately measuring micromole levels, this photosynthetically active radiation meter supports better crop quality, more consistent yields, and more efficient use of your lighting investment. Whether you’re setting up a new lighting system, verifying manufacturer output, or fine-tuning existing fixtures, this quantum PAR meter gives you the confidence that your plants are receiving the right light, in the right place, at the right intensity.
