Flash Sale ✨ Apogee Instruments Apogee | MQ-610 | 400-750 Nm | EPAR Meter Harvest & Essentials ❤️

Need an industry leading ePar meter to quickly and accurately measure your room?  Measure photosynthetic radiation from 400-750nm, designed specifically to capture those far-reds between 700-750nm. With the assistance of their add on wand, it makes it easy to conduct spot checks to ensure canopy coverage is optimal!

This is designed by the Apogee Instruments’ engineering team under the direction of world-renowned crop physiologist, Bruce Bugbee, PhD, so rest assured that the best of the best have used, and had their part, in designing this. 

The sensor head 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. Unlike the sensor head, the handheld meter is not waterproof.

 

QUALITY ePAR METER – Unlike commonly available LUX or footcandle meters used for measuring light for human vision, our meters feature a laboratory-grade ePPFD (extended photosynthetic photon flux density) optical detector precisely calibrated to measure the light intensity in µmol m^-2 s^-1 of the specific color wavelengths (including far-red) emitted by LEDs, HPS, MH, sunlight, and other light sources utilized by plants for photosynthesis. The sensor contains a precision silicon photodiode detector, a custom optical filter, and an acrylic diffuser all housed in a self-cleaning, dome-shaped, anodized aluminum sensor head.

EXTREMELY ACCURATE & STABLE – Precisely measures and combines the intensity of all photons between 400 and 750 nm to give a single ePAR reading in µmol m^-2 s^-1 within 5 % uncertainty. Our ePAR meter has a stable, accurate calibration with an accuracy drift rate of less than 2% per year.

THREE MEASUREMENT MODES – The meter has a spot measurement, sample, and log mode and will record an integrated daily total in mol m^-2 s^-1. Sample mode will record up to 99 manual measurements and log mode will power the meter on and off to make a measurement every 30 seconds. Every 30 minutes, the meter will average the sixty 30 second measurements and record the averaged value to memory, up to 99 averages. Once full, it will overwrite the oldest measurements with new ones. A daily light integral will be recorded from the 48 averaged measurements for a day’s worth of readings and is downloadable via Apogee AC-100 cable.

MADE IN THE USA – All meters are designed, built, and calibrated at our headquarters in Logan, Utah, USA. Apogee Instruments has been creating research-grade instruments for scientists and serious growers for over 25 years. All meters are backed by our industry leading four-year warranty and supported by our world-class, US-based customer support team.
