Apogee InstrumentsApogee Instruments MQ-610: 400-750 nm ePAR Quantum Meter Bundle w/AM-330 Telescopic Sensor Wand - Meter for Extended Range LED Greenhouse Grow Lights, Sunlight, and Plant Care
Main highlights- RUGGED DESIGN: The sensor head is made of machined aluminum and fully potted, making it waterproof and rugged. The tangle-free cable facilitates measurements over a large plant canopy, while still allowing the user to view the high-contract display screen.
- PREMIUM QUALITY: The MQ-610 is preferred by scientists and serious growers for accurate PAR measurements. Our meters stay accurate and reliable while other budget PAR meters can have readings drift by over 50%.
- NEW ePAR RANGE: Lab-grade measurement reveals photosynthetic activity from 400-750 nm, expanding beyond the traditional 400-700 nm PAR range. Dr. Shuyang Zhen and Dr. Bruce Bugbee spearheaded the defining research. The MQ-610 accurately measures far-red photons (700-750 nm), vital for next-gen LED fixtures, sunlight, and other sources not captured by standard PAR meters.
- MANUFACTURED IN THE USA: All meters are backed by our four-year warranty and supported by our US-based customer support team.
- DR BRUCE BUGBEE: Apogee PAR meters have been designed and refined by Dr. Bruce Bugbee, a world-famous crop physiologist.
