Apogee Instruments - MQ-350: PAR Bar with Handheld Meter

Brand: Apogee Instruments

The Apogee MQ-350 is a line-quantum PAR bar with a handheld meter that averages PPFD across ten quantum sensors, giving a true spatial-average canopy light reading instead of a single point.

Spatial averaging is the right way to characterize light uniformity over a bench or canopy, where single-point meters can mislead. The bar reports average PPFD and supports DLI logging.

Key Features

• Ten quantum sensors averaged into one spatial reading
• Handheld meter with sample logging and DLI
• Ideal for canopy uniformity and bench mapping
• Rugged bar for repeated field use
• 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-350 measures what a single-point meter cannot: the average light a whole canopy actually receives.

Ideal Applications

• Canopy light-uniformity mapping
• Bench and rack PPFD averaging
• Fixture layout and commissioning
