The OV-type egg candling device is a transillumination instrument for poultry operations, used to inspect eggs by passing concentrated light through the shell. Candling reveals what no external inspection can: fertility and embryo development in hatching eggs, hairline shell cracks, blood spots and internal defects in table eggs.
The OV design checks ten eggs per cycle across its illumination cores, making routine inspection of incubator trays practical at farm scale rather than egg-by-egg. The compact unit measures 135 mm in its principal dimension and is classified under the Russian poultry-equipment nomenclature.
Removing infertile and dead-germ eggs early in incubation frees incubator capacity, prevents contamination from rotting eggs and lifts overall hatch economics — which is why candling remains a standard checkpoint in every serious hatchery protocol. At nine dollars per unit with a 200-piece minimum, the device addresses poultry-equipment distributors, hatcheries, agricultural cooperatives and farm-supply retailers.
