SC25V
SC21 & SC25V Combined pH Electrodes
（non-flow）
Yokogawa continuously is improving the present pH sensing portfolio and designing new pH sensors integrating the latest improvements into the new design and upgrading our present.
The SC25V is the latest addition to the family. Yokogawa’s first combination pH sensor in a 12 mm design with an external Liquid earth. A new design made it possible to create a large electrolyte volume making this sensor last longer then most other comparible pH electrodes.
The SC21 series already for many years Yokogawa’s trusted range of combination pH electrodes still has the same variety of choices making it easy to find the best electrode for each application.
Features SC25V
• External titanium Liquid Earth
• Pt1000 integration in pH compartment giving highly accurate temperature compensation
• ATEX certified : ATEX II1G Ex ia IIC T3...T6 Ga
• CIP and Steam cleaning possible
• Large internal KCL volume giving the sensor a longer life time
• Measuring in Pure Water applications from 10 μS/cm
• Variopin connector
• SC24V-ALP25 for chemically harsh applications and high temperatures
• SC25V-AGP25 for all General Purpose applications

SC24V
SC24V Differential pH sensor
The SC24V it a differential pH sensor. This means that the reference is not a （liquid） junction but a glass sensor which does not respond to pH changes （within the applicable range of the sensor）. Therefore the sensor is truly maintenance free and the output voltage of the sensor depends only on the salt concentration of the process.
The sensor responds to pH changes rather than analyzes the accurate pH value. In that sense it is best to describe the sensor as pH control sensor rather than pH measuring sensor.
A pH sensor measures the voltage that the pH membrane measures as function of the pH value of the process sample. This voltage is then compared with the mV output of a reference cell that is independent on the pH value of the sensor
In most pH control applications the salt concentration is rather constant, so the output of the SC24V differential sensor is only dependent on the pH of the process.
A rule of thumb is that a change in salt concentration of +/- 25%
has an effect of less than 0.1pH on the pH reading.
