withstand pressure spheres made by glass(6,700mType)

Model:GGL-10

This withstand pressure glass balls incorporate a marine research apparatus at inside and use, It comes to be able to connect a cable for direct hydrophones and a cable for communication to a glass ball.
In addition, It comprise a vacuum port to decompress the withstand pressure glass ball, and the outside is protected by a hard hat and becomes able to carry it.
Because this glass ball does not have impurities, transparency is very high and we enclose the video equipment such as cameras inside and can use it.
In addition, processing precision is very high and, in the join of the top and bottom hemisphere, can work without minding the direction of the join at the time of enclosure and boasts of the hemisphere of other glass balls and precision as you may change it.
