MEASURING CELL OF SODIUM ANALYSER Russian patent published in 2008 - IPC G01N27/27 

FIELD: measuring devices.

SUBSTANCE: measuring cell of a sodium analyser consists of three serially connected flowing chambers. In the first chamber along the flow of the medium, a temperature sensor is mounted. In the second chamber there is a test electrode and the main electrode is in the third chamber. The first chamber has two channels, linking it to sources of the controlled media and an alkaline reagent. The chamber is divided horizontally using a partition wall with a central opening on two parts, the upper part on which is mounted a temperature sensor and has input channels. On the lower part of the channel there is an electroconductivity sensor. The input channel, linked to the medium, is located near the upper filling level of the liquid in the upper part of the chamber. The axis of the given channel is at a tangent to the wall of the chamber. The output section of the second input channel is located over the horizontal partition wall, lower than the output section of the first input channel.

EFFECT: lower inertia, increased accuracy and stability of measurements.
