AH-PARUV Quantum PAR Meter,320-750nm. Red | Blue Light Seperate PPFD,Test UVA Radiation Intensity,3 and 13ft Cable. Record History PAR.

Test PAR and UVA Radiation Intensity. The PAR sensor IC inside is from a famous Japan semiconductor company. Show the PAR of Blue, green, and red in the light seperately. Plants typically requires more blue light during the seedling and vegetative stages, while during the flowering, a higher level of red light is needed. Show the UVA intensity. Help to optimize growth conditions, enhance photosynthesis, improve plant quality, and reduce stress and damage. Has the functions of HOLD and MAX for the reading. Record history PAR that makes drawing the PAR distribution map easier. Within a 3ft and a 13ft par sensor cable. All right for PAR testing at the high or the distant.
