The Maxibright Quantum PAR Meter gives growers the power to measure real-world light output with precision and confidence. Designed for both professional and hobbyist use, this portable device measures Photosynthetically Active Radiation (PAR) – the light plants actually use to grow – with exceptional accuracy. Whether you’re comparing LED fixtures, validating PPFD maps, or fine-tuning your lighting setup, the MBPAR01 provides clear, consistent readings that cut through marketing claims.

Featuring a wide measurement range from 0 to 3999 μmol/m²/sec, ±1 μmol/m²/sec repeatability, and a large LCD display, it delivers reliable data at a glance. Lightweight, tripod-compatible, and easy to operate straight out of the box, it’s the ideal tool for grow rooms, greenhouses, and grow shops alike.

Each kit includes the main meter unit, a precision sensor (¼” screw mount compatible), coiled and straight sensor cables, AAA batteries, and a user manual. Simple zero calibration, data logging, and factory reset functions ensure accurate use across multiple environments.

Backed by Maxibright’s reputation for transparency and performance, the Quantum PAR Meter empowers users to test any grow light – ours or others – and see the numbers for themselves.
