The manually operated retractable fitting permits installation and removal of the sensor under process conditions so that the affected circuit or main current does not need not be interrupted. The primary fields of application of the retractable holder include pH measurements in closed-loop circuits or measurements in the supply and return of wastewater treatment plants. The retractable fitting can also be installed in container side walls, which allows removal of the sensor without needing to drain the container beforehand. The fitting permits the installation of a sensor with Pg 13.5 thread and an installation length of 120 or 225 mm.
