The invention provides sensing devices for measuring an electrochemical parameter in a reactor. The sensing devices include one or more electrodes, a fastener comprising a female part and a male part, a sealant inside an internal cavity of the male part, a spacer inside the internal cavity of the male part adjacent to and abutting the sealant, and a connector for connecting the spacer and the sealant. The male part, sealant and spacer include one or more channels through which one of the one or more electrodes passes. |
