摘要： A modular-construction measurement probe comprising a component designed as a diaphragm module and, connected to the diaphragm module, a rod electrode. The diaphragm is made up of at least three layers, the second layer having a much higher permeability than the first or third layer with respect to the gases and/or non-ionic compounds being determined. The first layer and the third layer are made of chemically resistant material. The three layers are preferably permanently bound to each other to give a uniform diaphragm structure, a support material in the form of stainless-steel gauze being mounted in the second layer. The probe is also fitted with a pressure-compensation system which makes it possible to compensate for pressure differences of the order of 20 bar which occur in operation between the measurement medium and the interior of the probe. The probe can therefore be steam-sterilized without problem. It is particularly suitable for use in the amperometric determination of oxygen.

摘要： Each connector part is provided with an electrically insulating body member and at least two pole contacts. A shield surrounds each associated electrically insulating body member. A position-fixation device serves to positionally retain the connector parts when intercoupled with one another. To impart to each connector part as smooth as possible and niche-free surface there is provided at the end face thereof one or more contact pieces, depending upon the number of pole contacts or poles contemplated for such connector part. Each contact piece is situated at least approximately in the plane of the end face of the associated connector part. Each such contact piece flushly bears against an associated contact piece of the other connector part when the connector parts are intercoupled with one another, and the contact pieces of one connector part are resiliently pre-biased in their contact-making direction. The electrical connector is relatively maintenance-free, prevents the accumulation of dirt and moisture and thus is exceedingly functionally reliable.

摘要： A measuring probe in which the electrolyte is in the form of a highly viscous gel produced in situ from an ion-permeable polymer and a neutral salt suspension. Homogeneously suspended neutral salt particles in the gel cause the gel to have a turbid appearance which disappears progressively as the suspended neutral salt particles pass into solution, thus indicating at all times the state of aging of the electrolyte. The additional presence of silica gel renders the probe potential resistant to pressures in excess of 10 bars.
摘要翻译：测量探针，其中电解质是由离子可渗透聚合物和中性盐悬浮液原位产生的高粘度凝胶形式。在凝胶中均匀悬浮的中性盐颗粒使凝胶具有浑浊的外观，随着悬浮的中性盐颗粒进入溶液而逐渐消失，因此一直表明电解质的老化状态。硅胶的额外存在使得探针电位对超过10巴的压力有抵抗力。
