Advances in pH Measurement in High-Temperature Biotech Processes
at the junction. However, depending on the material of the junction and the ionic strength of the sample solution, there will be an uncertain junction potential built up, which can cause errors in the measurement. The new steamsterilizable pH sensor uses a SiO2/ Al2O3-based porous ceramic

Humidity sensors
the humidity was high. Electronic sensors have replaced most mechanical systems today because of their accuracy, dependability, and lower costs. Electronic RH sensors typically fall into the resistive or capacitive category. Capacitive RH sensors are built on a substrate of glass, ceramic, or silicon

This class of liquid junction allows only the ions of the electrolyte to pass through the junction and into the test sample. Diffusion
