Mettler Toledo InPro 3253/120/PT1000 Pre-pressurized, Liquid-filled, Low-maintenance In-line pH Sensor with PT1000 Temperature Compensation

The Mettler Toledo InPro 3253/120/PT1000 is a high-performance, in-line pH sensor designed for accurate and reliable pH measurement in demanding environments such as biotechnology and biopharmaceutical production, food and beverage processing, and chemical industries. This sensor features:

• Pre-pressurized liquid electrolyte reference system with a ceramic diaphragm and Argenthal silver-ion trap cartridge, ensuring stable operation in sulfide-containing or harsh chemical environments.
• Built-in PT1000 temperature sensor for precise temperature compensation within the operating range of 0 °C to 100 °C.
• Compact 120 mm shaft length, suitable for installations requiring limited insertion depth.
• Capability to withstand pressures up to 4 bar gauge, making it ideal for use in sterilization-in-place (SIP) and clean-in-place (CIP) processes.
• Designed for repeated steam sterilization/autoclaving cycles without performance degradation, ensuring durability in bioprocessing workflows critical for molecular diagnostics and biomanufacturing.
• Process connection with Pg 13.5 thread and a VP-type connector, facilitating integration into standard process lines.

This sensor is essential for applications demanding real-time pH control under sterilized or hygienic conditions, widely used in fermenters, bioreactors, and wastewater treatment setups. Its durability and precision make it highly suitable for synthetic biology research environments requiring robust pH monitoring solutions that contribute to optimized cell culture and enzyme process control tasks within biotechnology fields.
