The user can designate up to 4 choices of wavelength at 350nm-1100nm of visible rays, thus it is being used in various fields such as chemistry, environment(water quality, air, soil), food, bioassay for residual pesticides, etc. In case of bioassay for residual pesticides to measure the inhibition level of residual pesticides or water analysis to measure the COO, TN, and TP levels of water, faster and more convenient measurement is possible with commercial test reagent
