Apogee Instruments MQ-650/AM-330 Bundle - Underwater/Reef Tank ePAR Quantum Meter Bundled with AM-330 Telescoping, Submersible Sensor Wand - Includes Apogee Instruments Neoprene Case

Brand: Apogee Instruments

Features:

• DR BRUCE BUGBEE: Apogee PAR meters have been designed and refined by Dr. Bruce Bugbee, a world-famous crop physiologist.
• UNDERWATER ACCURACY: The MQ-650 ensures precise, extended PAR measurements underwater by applying an immersion effect correction factor. It measures photons between 400 and 750 nm, providing a single 'ePAR' reading in µmol m-2 s-1 with less than 5% uncertainty. Its stable calibration boasts an accuracy drift rate of under 2% per year, unlike hobby-grade meters.
• FEATURES: The rugged detector measures photosynthetic photons from 400-750 nm from any light source by taking instantaneous or logged measurements; immersion correction-factor calibrated in for accurate UNDERWATER par-measuring. Bundle includes AM-330 UNDERWATER SENSOR WAND: This wand extends up to 36.25” (92cm), as measured from the end of the handle to the center of the mount making it ideal for reaching down into reef aquarium tanks.
• 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.
• 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. NOTE: Handheld-meter display is NOT waterproof
• MANUFACTURED IN THE USA: All meters are backed by our four-year warranty and supported by our US-based customer support team.
