ABSTRACT OF THE DISCLOSURE A probe system is provided which may be removably in- stalled in-line in a pressurized pipe line to determine the pH of the fluid flowing therethrough. The probe system comprises a pipe assembly mounted on the pipe line for providing access to the interior of the pipe line, and valve means for closing and opening the pipe assembly, the valve means being disposed medially of the pipe assembly. A sleeve is mounted on an outer end of the pipe assembly, the sleeve having a bore opening into the pipe assembly, and a pH probe assembly is telescopically mounted in the sleeve, the probe assembly extending through the sleeve bore and through the pipe assembly, the probe assembly being operable to convert the pH of the fluid flowing through the pipe line to an electrical signal representing the acidity of the fluid, the probe assembly having a. sensor head portion and an electrode dis- posed at an inner end of the sensor head portion within the pipe line. Sealing means are provided whereby a fluid-tight seal between the probe assembly and the sleeve bore is effected. A protector shield is secured to the probe assembly the protector shield including an elongated flange disposed outwardly spaced from and adjacent to said sensor head portion on the upstream side of said sensor head portion within the pipe line, the protector shield being operative to protect the sensor head and the electrode from dynamic fluid flow forces within the pipe line on the upstream side while allowing exposure of the sensor head portion and the electrode to the fluid in the pipe line on the downstream side.
