Maxibright PAR Meter
The Maxibright PAR Meter is a precision tool designed to measure Photosynthetically Active Radiation (PAR)—the spectrum of light (400–700 nm) that plants use for photosynthesis. PAR values are measured in micromoles per square meter per second (μmol/m²/s), helping growers understand how much usable light is reaching their canopy.
This meter is essential for indoor horticulture, greenhouses, and grow rooms, providing accurate readings to optimize light positioning, distribution, and intensity for maximum plant growth and yield. It works with all major light sources including LEDs, HPS, MH, CMH, and fluorescent lights.
How to Use the Maxibright PAR Meter
What’s Included
PAR sensor (connected via cable)
Digital display unit
Battery (usually pre-installed or requires AA/AAA)
User manual
Step-by-Step Instructions
Power On the Meter
Press and hold the power button until the screen turns on.
Position the Sensor
Place the sensor face-up at canopy level (or wherever you want to measure light).
Ensure the sensor is flat and unobstructed by shadows.
Read the Display
The screen will display a number in μmol/m²/s – this is the PAR value.
High PAR values (e.g., 600–1000 μmol/m²/s) are ideal for flowering stages, while lower values (200–400) suit seedlings and veg stages.
Take Multiple Readings
Move the sensor to different areas of the grow space to ensure even light distribution.
Average the readings if needed for a more complete picture.
Adjust Your Lighting
Based on the readings, adjust the height, angle, or intensity of your grow lights.
Ideal PAR ranges vary by growth stage:
Seedlings: 100–300 μmol/m²/s
Vegetative stage: 400–600 μmol/m²/s
Flowering stage: 600–1000+ μmol/m²/s
Power Off After Use
Press and hold the power button to turn off the meter and save battery life.
Tips for Best Use
Avoid direct sunlight on the sensor during indoor readings.
Clean the sensor lens occasionally for accuracy.
Use during different times of day to track light consistency.
