The Treegers Quantum PAR Meter is a professional-grade instrument designed to measure Photosynthetically Active Radiation (PAR) with exceptional accuracy. Engineered for growers and lighting specialists, it quantifies Photosynthetic Photon Flux Density (PPFD) across the 400–700 nm range, helping users fine-tune lighting performance for optimal plant growth. Whether calibrating LED fixtures or analysing canopy uniformity, this compact meter provides reliable, repeatable readings every time.
With a measurement range of 0–4000 µmol/m²/s, the Quantum PAR Meter captures even subtle variations in light intensity. A remote sensor attached by a 1.5 m coiled cable and 3.5 m straight extension ensures flexibility in testing across multiple points. Readings can be stored (up to 99 records) and reviewed to track Max, Min, and Average values. Built to withstand tough grow environments, it features wide operating tolerances, low power consumption, and an ergonomic display design, making it an indispensable tool for serious indoor cultivators.
