Maxibright PAR Meter

The Maxibright Quantum PAR Meter (MBPAR01) gives growers accurate, real-world light measurements so they can optimise any indoor grow setup with confidence. Because it measures Photosynthetically Active Radiation (PAR) – the exact wavelengths plants use for photosynthesis – it allows you to verify fixture performance, compare LEDs, and fine-tune light placement for healthier, faster growth.

Designed for both professionals and hobby growers, the MBPAR01 offers a wide measurement range from 0–3999 μmol/m²/sec and an impressive ±1 μmol/m²/sec repeatability. As a result, you get precise and consistent readings every time. The large, easy-to-read LCD screen makes data checking simple, while the lightweight, portable design works perfectly in grow rooms, tents, greenhouses, and retail grow shops.

You can mount the external sensor to a tripod via the ¼” threaded insert, giving you hands-free, stable measurements for PPFD mapping or side-by-side light testing. The meter also includes essential functions such as zero calibration, data logging, and factory reset, so you always maintain accuracy across different environments.

Each kit comes ready to use with the main meter unit, a high-accuracy sensor, coiled and straight cables, AAA batteries, and a user manual. Backed by Maxibright’s commitment to transparency, the Quantum PAR Meter lets you test any grow light—Maxibright or otherwise—and see the real numbers yourself.
