A device (110) for performing measurements on a seabed (3), comprises a chamber (111) containing a sensor (120) and a fluid (115) at a constant temperature and at an ambient pressure. This removes the need for calibration in large ranges of both pressure and temperature. In addition, this eliminates the need to wait until the sensor (120) has achieved ambient temperature, and thereby achieves a desired accuracy of the recordings from the sensor while decreasing the operation time. The device preferably comprises an insulating layer (113), an internal temperature stabilising device (130) and a circulating device (131) to ensure a constant temperature and low temperature gradients within the chamber (111). The pressure within chamber (111) may be equalised to ambient pressure by a pressure inlet (112).
