Best Par Meter For Led Grow Lights (2024 Updated)

The MQ-500 full-spectrum quantum meter is a premium tool designed by world-renowned crop physiologist, Bruce Bugbee, PhD, and is the top choice for leading scientists and serious growers. This package includes an AM-310 telescopic sensor wand that extends up to 33 inches for measuring hard-to-reach places, and a neoprene carrying case. Measuring PAR is critical in the precision growing of plants and other photosynthetic organisms in greenhouses, growth chambers, farms, gardens, aquariums, and additional agricultural systems.

Unlike cheaper LUX or footcandle sensors, which are marketed as grow light meters but are meant for human vision, our meters feature a laboratory-grade PPFD (photosynthetic photon flux density), or “quantum,” optical detector that is precisely calibrated to measure the light intensity in µmol m-2 s-1 of the specific color wavelengths emitted by LEDs, HPS, MH, sunlight, and other light sources utilized by plants for photosynthesis. This quality quantum meter is extremely accurate and stable, precisely measuring and combining the intensity of all photons between 400 and 700 nm to give a single PAR reading in µmol m-2 s-1 within 5% uncertainty. Our meter has a stable, accurate calibration with an accuracy drift rate of less than 2% per year, unlike hobby-grade PAR meters.

The quantum sensor head of this meter is machined aluminum and potted solid with epoxy for years of use in harsh environments, including underwater. The handheld meter is attached by a cable and displays real-time readings, records samples, and logs average intensity and daily light integral (DLI) measurements. However, the handheld meter is not waterproof, unlike the sensor head. This rugged and easy-to-use meter is precisely what serious growers and scientists need to accurately measure the photosynthetically active radiation (PAR) from all light sources.

The 3-foot long 3-piece heavy-duty steel extension wand is a must-have for anyone looking to accurately measure light in their indoor garden. This extension wand comes with a soft carry case for easy storage and transport. It features three different modes to suit various needs.

The FH-100 is a specialized meter designed to measure accurate LUX or PPFD values based on different spectra of LED | CMH, HPS and SUNLIGHT. With its specific design, it ensures that human eyes and plants have the correct perception of these light sources. When testing PPFD in a closed tent, the FH-100 provides the most accurate value by closing the tent completely, unlike other meters that require opening one side of the tent causing light leakage and inaccurate readings.

This meter saves manpower as only one person is needed to test the illuminance of the light source at different distances or different powers. While testing, there is no need to hold the light meter, preventing light blockage by the user's body. Additionally, the FH-100 can test illuminance values in small spaces or areas that are inaccessible to humans.

This meter is essential for growers who require accurate LUX or PPFD readings to ensure the best possible yield. The FH-100 offers ease and convenience in testing, and its lightweight design makes it easy to carry and store.

The DLI mode of this product calculates the average light over 24 hours, which is the total amount of light energy delivered to a plant over an entire day. The Scan mode, on the other hand, averages PAR over any area scanned, which is the amount of light energy that is available for photosynthesis in plants. The Spot mode takes instant PPFD readings, which is the amount of PAR that is available for photosynthesis at a specific point in time.

This product comes with a built-in stand, stake, and magnetized screw, which allows the user to hold the meter to metal. The Extension Wand is sold separately.

The product is perfect for those who want to monitor the light intensity and duration of their plants with ease. The three different modes provide flexibility and accuracy in measuring light, making it a valuable tool for both indoor and outdoor gardeners.
