Apogee MQ-610 ePAR meter | 400 - 750nm Quantum sensor with handheld meter and 2m cable

This Apogee Quantum PAR meter measures the extended ePAR range from 400nm to 750nm. If you are measuring grow light spectrum which includes a significant proportion of FAR red this is the PAR meter you need. The latest research has demonstrated that far red is photosynthetically active but the wavelengths between 700nm to 750nm are not measured by traditional Quantum PAR sensors. The Apogee ePAR sensor measures the PAR spectrum and far red spectrum in one sensor. 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. More info (Taxes, Shipping & FAQs)
