Conductivity measurements for nuclear power plants

Valmet conductivity meters (formerly known as Kemotron) are designed to work in the reactor island of the nuclear power plant.

Valmet Conductivity meters are resistant up to 1.00E +05 Gy of radiation. From health and safety point of view Valmet conductivity meters are ideal in nuclear power because of the long life time and no need for maintenance.

Valmet Dual conductivity TCU has built-in cable compensation which enables up to 50 m sensor cables without loss of accuracy. The TCU can be installed behind radiation shields making operating the unit even safer. Two sensors can be used with one TCU.

Valmet conductivity meters are extensively used in Swedish nuclear power plants. Nuclear power has number of special requirements for equipment testing. Valmet offers service to do required tests in our production.
