TrolMaster Full Spectrum Quantum Sensor（MBS-PAR） TM-7 thus making this pump aThe Full Spectrum Quantum Sensor (MBS PAR) provides accurate and cost effective measurement of photosynthetically active radiation (PAR) from all light sources used to grow plants. The full spectrum quantum sensor has a spectral range of 389 to 692 nm 5 nm. The improved spectral response increases the accuracy of LED measurements. Used in conjunction with the Hydro X controller, the PPFD sensor will AUTOMATICALLY increase or decrease the output level
