Analog pH sensor
Ceraliquid CPS41

Ceraliquid CPS41 - Analog pH sensor with refillable liquid KCl electrolyte

The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.

Glass electrode for applications with fast-changing medium compositions or low conductivity

Ceraliquid CPS41 is the analog high performer for pH measurement in harsh chemical applications and media with low conductivity or a considerable content of organic solvents. The sensor is designed for fast response guaranteeing you high process safety even in applications with quickly changing medium compositions.

Measurement and control aspect of pH using inductively coupled with bidirectional Memosens technology in flue gas desulfurization process
White Paper CP971C pH measurement and control in a power utility is an
integral part of process. The scrubber efficiency is highlydependent on
the pH. Numerous opportunities were revealed for saving time, as well as
the cost and materials in power plants. In afossil fuel power plant,
the
chemical energy stored in coal, oil, natural gas, shale oil, oxygen and
air
is converted into thermal, mechanical and finally into electrical
energy. In
other words, water is heated to steam, which spins a steam turbine. The
steam turbine drives an electrical generator.
