BTM-2000 is a digital curing light radiometer for measuring the intensity of LED curing light. The spectral response range is from 400nm to 540nm. The peak sensitivity wavelength is 460nm. The measuring unit is mW/cm2, and the data range is from”0″ to “1999”, if the value of test is more than 1999, the data of the indicator will be showed”1″. When battery power is low, the data of the indicator will be showed “LOBAT”, please replace the battery with a new battery at the moment
