TrolMaster Full Spectrum Quantum Sensor MBS-PAR

The 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 of your supplemental lighting systems to continuously maintain the exact lighting level (in PPFD) that the user selects. 

  "Sensors should remain dry and clean to prevent premature failure. Do not spray foreign substances or allow water / condensate on the sensors"
