Apogee Instruments - MQ-610: ePAR Quantum Meter (400-750 nm)

Brand: Apogee Instruments

The Apogee MQ-610 is a handheld ePAR quantum meter that measures the extended 400 to 750 nm photosynthetic range, capturing far-red photons accurate under all light sources, including narrow-band and broad-spectrum LEDs.

The meter displays real-time intensity, logs samples, and computes daily light integral (DLI), with a separate sensor on a 2 m lead for easy canopy placement.

Key Features

• Extended ePAR measurement, 400 to 750 nm
• Real-time readout with sample logging and DLI
• Accurate under sunlight, HPS, and LED fixtures
• Separate waterproof sensor on a 2 m lead
• Built and calibrated in Logan, Utah; NIST-traceable, made in the USA, and backed by an industry-leading 4-year warranty.

Why Choose This Model

The MQ-610 lets growers measure the same extended ePAR range used in modern photobiology research in a simple handheld meter.

Ideal Applications

• ePAR spot checks under LED fixtures
• Far-red-inclusive light measurement
• Greenhouse and indoor cultivation
