Navigating Corrosive Media: Selecting the Right SC42 Sensor Body
Measuring conductivity in corrosive environments requires more than accuracy; it demands long-term reliability under chemical and mechanical stress. Aggressive media such as acids, oxidizers, and industrial effluents can degrade unsuitable sensor materials, leading to drift, leakage, or unexpected failure.
This guide helps you confidently select the right SC42 conductivity sensor body, focusing on the key differences between PVDF and PTFE materials:
- PVDF: Ideal for applications requiring high mechanical strength and pressure resistance, such as abrasive or pressurized processes.
- PTFE: Designed for extreme chemical resistance, making it the preferred choice for highly aggressive oxidizing media.
By balancing chemical compatibility, pressure, temperature, and mechanical conditions, this guide supports better material selection, helping you reduce maintenance, extend sensor lifetime, and improve process reliability.
