The primary considerations when selecting a process adaption are related to the process media, installation point and your cleaning and calibration requirements. Based on your specific process requirements, you will want to consider if you need a stationary or retractable design, what process connection compatibility you require, insertion length, wetted materials, and whether a sensor protective cage is needed to protect the sensor tip from damage in high particle load samples. Your local METTLER TOLEDO representative can help you to select the right process adaption to meet your specific requirements.
