Abstract
The invention relates to a device for measuring the electrode potential of the reinforcement in underwater concrete. The device is of the type comprising a reference electrode placed against the facing of the concrete and a voltmeter connected to the reference electrode and to the reinforcement. The reference electrode is disposed in a bell suitable for pressing in watertight manner against a facing of the concrete, thereby delimiting an enclosure. The device further includes means for injecting compressed air into the enclosure and means for enabling the water imprisoned therein to escape.
