Mettler Toledo InPro (Unused Boxed) 3253/120/PT1000 Pre-pressurized, liquid-filled, low-maintenance pH sensor

These items are unused and boxed in original packaging. Supplier Catalogue No. 52002567. The Mettler Toledo InPro 3253/120/PT1000 is a high-performance in-line pH sensor/electrode with specific features: a pre-pressurized, liquid-filled, low-maintenance pH sensor. It has a built-in PT1000 temperature sensor for temperature compensation. The sensor length (shaft) is 120 mm, suitable for installations with limited insertion depth. It is sterilizable/autoclavable and optimized for steam sterilization or autoclaving cycles, withstanding repeated sterilization without performance loss. Reference system: pre-pressurized liquid electrolyte, with a ceramic diaphragm, and includes an Argenthal cartridge with a silver-ion trap (for better performance in environments with sulfides etc.). It can handle pressures up to 4 bar gauge and works in the range 0 °C to 100 °C. It has a process connection thread of Pg 13.5, and its connector is of “VP” type. This sensor is ideal for real-time, reliable pH measurement under harsh or demanding conditions, such as biopharmaceutical/biotechnology production (e.g., fermenters, bioreactors with frequent sterilization), hygienic food or beverage processing (CIP/SIP), chemical processing (extreme pH, temperature, contaminants), and water/wastewater treatment requiring a durable, robust probe.
