Condition: used, This item is unused and in the original packaging We have a quantity available The InPro 3253SG 120/PT1000 is an in-line industrial pH electrode (probe) intended for continuous process measurement rather than simple lab spot checks. It integrates both the pH sensing element and temperature compensation in a single unit, allowing accurate, real-time pH measurement in process lines, tanks, fermenters and reactors Physical & Mechanical - Sensor shaft length: ~120 mm — relatively short, good for installations with limited insertion depth. - Process connection: Pg 13.5 threaded connection. - Connector type: VP industrial connector for secure integration. - Pressure rating: Up to ~4 bar gauge. Temperature & Compensation Dksdpoy Iw Etsfx Al Asu - Built-in PT1000 temperature sensor — provides temperature compensation for accurate pH reading. - Operating range: ~0 °C to ~100 °C. Sensing & Reference System - Glass pH sensing membrane with a pre-pressurized liquid electrolyte system — lowers maintenance and improves stability. - Ceramic diaphragm — stable reference junction. - Argenthal silver-ion trap cartridge — improves reference performance, especially in environments containing sulfides. - Sterilisation & Hygiene - Sterilisable/autoclavable — built to withstand repeated steam sterilization or autoclave cycles without losing calibration or performance. Certifications & Approvals - Typically supplied with industrial and safety certifications (e.g., ATEX, IECEx and CE) for use in hazardous zones and hygienic processing. pH Range - Suitable for pH measurement typically within 0 to 12 (depending on membrane type). Summary In essence, the Mettler Toledo InPro 3253/120/PT1000 is a high-performance industrial pH electrode designed for robust, low-maintenance in-line monitoring with integrated temperature compensation, suitable for sterilizable and process‐critical environments. Its pre-pressurized reference and rugged build help deliver stable pH measurements in demanding applications.

Condition: new, 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 some specific featuresA 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, which is relatively short, making it suitable for installations with limited insertion depth. It is sterilizable/autoclavable and optimized for steam sterilization or autoclaving cycles. That means it can withstand repeated sterilization without losing performance. 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 process connection thread of Pg 13.5, and its connector is of “VP” type This sensor would be used in settings where real‑time, reliable pH measurement is needed under harsh or demanding conditions. Some examples: Dsdpfx Alexv Dv Ej Aoku - Biopharmaceutical / biotechnology production, e.g. fermenters, bioreactors, where sterilisation (e.g. steam) is frequent and you need accurate pH control. - Hygienic food or beverage processing where cleaning and sanitisation/sterilisation are done in‑place (CIP / SIP). - Chemical processing, especially where pH may swing extreme and environment may be harsh (high/low pH, temperature, maybe some contaminants). - Water/wastewater treatment in situations needing durable, robust probe
