PCT No. PCT/JP92/00974 Sec. 371 Date Apr. 2, 1993 Sec. 102(e) Date Apr. 2, 1993 PCT Filed Jul. 31, 1992 PCT Pub. No. WO93/03354 PCT Pub. Date Feb. 18, 1993.In a cell for measuring electrical conductivity, a container (2) and electrodes (1) are made of ceramics having high corrosion-resistant property. Insulating ceramics are used for the container (2), and conductive ceramics having resistance value of several k OMEGA .cm or less is used for the electrodes (1). The ceramics are far superior to glass in corrosion resistant property and mechanical strength under normal as well as high temperature conditions. Further, the cell is produced at lower cost than the one made of precious metal and has high corrosion resistant property and can be used under strong acid or strong alkaline conditions. It has high mechanical strength and can be used under high pressure and high temperature conditions and produced at low cost because precious metal is not used for the electrodes.
