Mel-SDD Shadow Detection Device

Mel-SDD Shadow Detection Device


Mel-8704R-SDD Shadow Detection, EMF meter, Thermometer, LED Flashlight

The New Mel-SDD Shadow Detection Device was designed to compliment the popular laser grids currently available. The purpose of the device is to measure very subtle light contrast variations and convert the changes into audible tones that your ears can easily discern. The Mel-SDD is compatible with a RED, GREEN and WHITE LEDs, and it comes with a RED LED illumination source which has a range of 75'. When a contrast variation occurs between the LED illumination source and the Mel-SDD, the audible tones will be heard. Ascending tones for light increase and descending tones for light decrease. Additional information can be found on YouTube and under Extended Specifications.
