Light Meter PAR Meter Up to 400,000lx and 6000umol/(㎡s) DLI Calculator Lux Meter PPFD Tester

  • Because the main spectra of LED | CMH, HPS and SUNLIGHT are different, human eyes and plants have different perception abilities for these light sources. FH-100 is specifically designed for different spectra to measure the most accurate LUX or PPFD..
  • When testing PPFD in a closed tent, you can close the tent completely and get the most accurate value by using our meter. While for other meters, you must open one side of the tent to do it, so the light will leak out and you can't get the most accurate value..
  • Save manpower. For example, to test the illuminance of the light source at different distances or different powers, with FH-100, only one person can complete it, instead of two people..
  • When testing, because you don't need to hold the light meter, you can avoid that the light is blocked by your body..
