Why Buy From Grow Tents Depot
  • Industry Leading ePar Meter: This device is perfect for accurately measuring photosynthetic radiation in your room. It ranges from 400-750nm and is specifically designed to capture the far-reds between 700-750nm. With the additional aid of a wand, conducting spot checks to ensure optimal canopy coverage is a breeze. This meter is from Apogee Instruments', designed under the guidance of the renowned crop physiologist, Bruce Bugbee, PhD.
  • Durable Construction: The sensor head is built using machined aluminum and solidly potted with epoxy, allowing for long-term use in harsh environments, including underwater conditions. The handheld meter, attached by a cable, displays real-time readings, records samples, and logs intensity averages as well as daily light integral (DLI) measurements. It's important to note that the handheld meter is not waterproof.
  • Quality ePAR Meter: Unlike typical LUX or footcandle meters, our meter features a laboratory-grade ePPFD (extended photosynthetic photon flux density) optical detector precisely calibrated for measuring light intensity in µmol m-2 s-1 of specific color wavelengths emitted by various light sources used for photosynthesis. The sensor contains a precision silicon photodiode detector, a unique optical filter, and an acrylic diffuser, all housed in a self-cleaning, dome-shaped, anodized aluminum sensor head.
  • Extremely Accurate & Stable: This device precisely measures and combines the intensity of all photons between 400 and 750 nm to provide a single ePAR reading in µmol m-2 s-1 within 5% uncertainty. It is highly stable and maintains accurate calibration with an accuracy drift rate of less than 2% per year.
  • Three Measurement Modes: The meter provides spot measurement, sample, and log mode. It records an integrated daily total in mol m-2 s-1, with the sample mode recording up to 99 manual measurements and the log mode power the meter on and off to make a measurement every 30 seconds. The meter will average sixty 30-second measurements taken every 30 minutes, recording the averaged value up to 99 averages. Once full, it overwrites the oldest measurements with new ones, and a daily light integral is recorded from the 48 averaged measurements, 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 boasts twenty-five years of creating research-grade instruments for scientists and serious growers. All meters are backed by our industry leading four-year warranty and supported by our world-class, US-based customer support team.
