...ed port on the bottom. Protective case, meter, soil stake, AAA batteries, USB-C cable, screwdriver, and QuickStart guide are included..
BUILT FOR SCIENTISTS AND SERIOUS GROWERS: Developed for use by the Apogee Instruments’ engineering team under the direction of world-renowned crop physiologist, Bruce Bugbee, PhD. Calibration is NIST traceable to accurately measure combined intensity of photons between 400 and 700 nm to give a single sunlight PAR reading within 5 % uncertainty. Unlike hobby-grade PAR meters that drift out of calibration quickly, our meter has a stable drift rate of less than 2% per year..
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..
