Retractable probe housing EXtract 840M

manual

Product description
EXtract 840M is a manually operated retractable probe housing with optional ball valve, manufactured in stainless steel, designed for inline pH measurement in pipes and vessels. Its long, flexibly adjustable immersion length enables deep sensor insertion into the process and allows sensor separation under process conditions for cleaning, calibration or removal together with the fitting. The design prioritizes safe handling and straightforward operation.
