Product Description

Turf-Tec Light Meter for Quantum PAR - Spot On
Model - LIGHT-PAR-W

The Turf-Tec Light Meter for Quantum PAR by Spot On is an affordable light meter that provides scientifically accurate Photosynthetic Active Radiation (PAR) light readings. This meter is designed for measuring PAR light indoors and outdoors regardless of light source type. It works well for Golf Greens, Sports Fields, Stadiums, greenhouse, agricultural fields, and R&D applications requiring reliable plant growth light readings. The chemical reaction of photosynthesis requires light. Unlike energy based light measurements, the quantum (quantity) of photons is measured since it can be directly tied to the number of these chemical reactions that can take place. The measure of all available light between the wavelength (color) range of 400 to 700 nanometers(nm) has been accepted as the best measure of light available for photosynthesis.The Turf-Tec Light Meter for Quantum PAR by Spot On is an affordable light meter that provides scientifically accurate Photosynthetic Active Radiation (PAR) light readings.

This is defined as quantum Photosynthetic Active Radiation (PAR) in units of μmol m-2 s-1. This is referred to as PAR light, PPFD, PPF, and Quantum light interchangeably and is the total quantity of photons in μmoles over the light spectrum from 400 to 700 nm hitting a one-meter square area every secondavailable for photosynthesis.

The Turf-Tec Light Meter for Quantum PAR by Spot On can also determine the total number of photons incident on one square meter over a 24-hour period. This is defined as the Daily Light Integral (DLI) and is displayed in moles per square meter per day. The typical range for DLI is 3 to 26 moles m-2 day-1. This is useful for understanding the average amount of light your cropseesin a day. One mole is equal to one million micromoles.The Turf-Tec Light Meter for Quantum PAR by Spot OnThe Turf-Tec Light Meter for Quantum PAR by Spot On
