Definitions
- the probe is drawn about double the actual size, the probe housing 6 having a height of about 30 mm (as viewed from the side, such as in fig. 1 ) and a diameter of about 35 mm, and the electrodes 1 , 2, 3 being about 25 mm in length and having a diameter of about 5 mm.
- each sensor electrode 1 will be comprised of an electric conducting material which is different from the electric conducting material in the other sensor electrodes 1 in the same probe, the materials exhibiting mutually different properties relating to the electrode potential.
- the electrode of the type Nos. 4-9 made of carbon (C), lead (Pb), copper (Cu), nickel (Ni) or palladium (Pd), are not reversable, i.e. they do not satisfy Nemst's equation with respect of the relation between potential and concentration.
- the change in potential as a result of the change in concentration will normally be less for reversable electrodes, typically in the range 20-50 mV for a change in the concentration having a factor of 10.
- All of the electrodes (type Nos. 1-8) have some sensibility as to the changes in temperature, in the order of 0,1 - 1 mV/'C. This sensitivity as to temperature is compensated by the recording of the temperature simultaneously with the carrying out of the potential measurement and is included in the calculation which preferably is done by means of a computer programme, as discussed above.
- the probe may also be of interest to combine the probe with the steel electrodes to carry out measurements of the corrosion potential and/or linear polarisations.
- the probe according to the invention may also be provided with one or mor steel electrodes for this purpose. Simultaneous measurements of environmental parameters and the corrosion of steel at the same location provide in many cases interesting possibilities and will be of great value.

Abstract
L'invention porte sur le moulage dans du béton d'un ensemble d'électrodes en vue de la mesure dans le béton de paramètres relatifs à l'environnement. Le système comporte un ensemble d'électrodes de détection (1), dont chacune est sensiblement composée d'un seul matériau. Les matériaux sont choisis de manière à ce que le potentiel d'une électrode de détection mesuré par rapport à celui d'une électrode de référence (2) varie en sens inverse en fonction des modifications de l'environnement dans le béton. Cette combinaison d'électrodes permet de calculer les paramètres relatifs à l'environnement, de déterminer ceux ayant trait à la corrosion et de renforcer le béton en conséquence.
