Candling monitors the development of the embryo within the egg allowing infertile eggs to be removed before they become infected and contaminate others. Egg candling also monitors the rate of enlargement of the airspace within the egg as a gauge of incubation humidity and for more detailed analysis of development such as vein growth. The Brinsea OvaView High Intensity egg candler is designed to be either hand-held or can be left on a work surface. Battery powered for convenience it uses very high output high efficiency LED illumination – so no bulbs to replace and no concerns about overheating the eggs during inspection. Supplied with both a flexible black ring for standard eggs plus a special ring for smaller eggs to seal against the eggshell. The larger power drain means that rechargeable batteries are needed – 4 AA batteries required but not supplied. Suitable for candling quail, pheasant and other dark or mottled eggs.
