MQ-610 ePAR Quantum Meter
The Apogee MQ-610 ePAR Quantum Meter measures extended photosynthetically active radiation (400–750 nm) for precise light monitoring in horticulture, hydroponics, and research applications. Developed under the guidance of Dr. Bruce Bugbee, it ensures reliable, laboratory-grade accuracy for optimizing plant growth.
Stock is confirmed with suppliers after order (typically within 1–2 working hours).
Product Description
The MQ-610 ePAR Quantum Meter is an industry-leading tool designed to measure the newly defined ePAR spectrum (400–750 nm), including far-red photons critical to plant development. Built by Apogee Instruments, this meter provides unmatched accuracy and durability for growers, horticulturists, and researchers who demand precise light monitoring to maximize yields.
Key Features
