TrolMaster (MBS-PAR) Full Spectrum Quantum SensorTrolMaster's Full Spectrum Quantum Sensor (MBS-PAR) provides the 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.Features & Benefits: Onsite Reading Plug & Play Package Content: 1 x Full-Spectrum Quantum Sensor 1 x 1/2” Post Clamp 1 x 4ft RJ12 Cable 1 x RJ12 T-Splitter 2 x 1/2“ End Cap Specification:Working Temperature : 32-122°F Working Humidity : ≤90% Package Dimensions : 160mm(L) x 56mm(W) x 86mm(H)
