The present invention relates to a device support for probes and instruments used in under-water measuring techniques. According to this invention, a submersible housing (1) contains the components of an electronic unit (4), of a control and adjustment system (5), of a power supply member (6) and of a transceiver unit (7), said components being maintained by a central support (2) provided with a flange (21). The housing (1) comprises at least two cup-shaped cylindrical parts (11, 12) which can be releasably assembled at their open sides (111) and which tightly surround the flange (21). The inner chamber defined by the housing is submitted to a negative pressure when in use. A ballast (3) is provided on the inner side of the housing (1) and can be connected with the evacuated inner chamber of the housing through a wear-resistant controllable valve (31) in order to ensure pressure balance. The ballast is further provided with a dosing pump (32) for supplying water into the ballast (3) from the water surrounding the housing (1)< > through a connection duct (33), the valve (31) and an exchange duct (331), or for discharging the water from the ballast (3) into the water surrounding the housing (1). The housing (1) is connected on the outside and at its upper part (11) to a buoyancy housing (17) comprising a plurality of buoyancy bodies (171) which can be removed separately. Additional probes and instruments (8) as well as fixations and other outer systems (9) are arranged on the outside and on the lower part (12) of the housing.
