Designed to compliment the popular RED & GREEN 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.
The Mel Meter Flashlight can also be used as a diffuse reflective sensor up to 5′ away.
The Mel-8704R-SDD works with:
* RED & GREEN LEDs
* A RED or GREEN Laser Grid
* A RED or GREEN Laser Pointer
* LED Flashlight
* The Mel Meter Flashlight can also be used as a diffuse reflective sensor up to 5′ away. This feature enables detection of reflective or solid objects that pass in front of the Mel Meter. Or, turn the Mel flashlight OFF to detect self illuminating or glowing objects in the field of view.
* You can use the light from a RED exit sign, street light coming through a window, or any other indirect “stable” incandescent light.Temperature and EMF Meter w/Glow in the dark buttons and flashlight built in
