Autek-Light-Meter-Tester-for-Testing-the-Intensity-of-Dental-LED-Curing-Light-White
put the light cure tip in the center over the detector window read the useful curing power in mw/cm2
Used to test the curing power of dental curing light etc.
Interpreting your results:
Under 300: indicates low output
300-500: test composite to determine curing time
500-800: use recommended curing time
Over 800: high output-reduce curing time appropriately
Measures useful curing energy up to 2000 mW/cm2
Detects blue light from 400-500 nanometers
