9000 Series pH & Redox Insertion Sensors • Combination glass pH electrode, • Sealed Ag/AgCl reference with coaxial ceramic junction • Single junction reference design • 6 Metres of cable with Tag ends (* Note: Dimensions in inches) The 9000 series pH & Redox sensors are designed for direct installation into a pipe or in the wall of a tank for continuous pH or Redox monitoring and control. These sensors have a large non-clogging peripheral reference junction, which is constructed in annular form around the sensing electrode. The 9000 series sensors have a Kynar body with a 0.5” NPT male threaded process connection. The sensors must always be installed at least 15 ° above horizontal for correct operation.
