Once you get the right urine detection light the next thing to do is to turn off the lights and look for green or neon spots. Tiny disparities in light frequency illuminate different organic traces shorter uv wavelengths tend to do better with urine.

02 23 2014 09 06 pm 4. Peedar meets ce rohs standards. The number of led bulbs also makes a difference in how easy it is to find cat urine.
This figure is just right because it is neither too high nor too low. A portable forensic light with the appropriate range of wavelengths a bluemaxx bm500 with a broad band wavelength of 390 500 nm sirche finger print laboratories inc raleigh nc was identified and purchased for our study. Best fluoresce at 420 and 450 nm when viewed through orange goggles.
Urine detectors come in various prices ranging from affordable to extravagant. The best kind of uv light is somewhere between 365 to 385 nanometers and has around 12 bulbs. Turn off all other lights close blinds curtains etc.
Make sure the area you are examining is as dark as possible. Pet urine is only visible under uv light and at specific wavelengths. The peedar has an optimum 365 370nm uv wavelength range for detecting invisible urine stains.
Uv light what we can see of it is near the low end of the visible spectrum it will be much easier to see the uv or near uv light 400nm when your surroundings are completely dark. You ll need to talk to someone in forensics for specific recommendations. Medical lamp companies were contacted.
For any black light for urine detection to be practical it needs to have the right wavelength. The recommended wavelength range is between 365 385 nm but 390nm and 395nm are still ideal for detecting urine. For best results we recommend going with 365 or 385 nm.
This is the best wavelength for urine detection to allow you to use cat or dog urine. Uvmonster black light uv flashlight is 70 brighter than other lights best choice for pet dog cat rodent urine detection. Professional grade ultra intensity 23 w 385 395 nm with 128 top quality led uv flashlight helps you to find urine stains even in indoor or streetlight.
A pet urine detector is essentially a flashlight equipped with an ultraviolet uv bulb and it emits a specific wavelength that causes urine to glow in the dark. They are almost useless in finding cat urine because they are too close to being visible light. What is the best wavelength for urine detection.
However there are other factors that affect visibility. We recommend getting one with a wavelength of about 365 385 nanometers.
