Sub-Zero Online pH Sensor Key Features
The LT3900L is engineered with advanced materials to ensure maximum durability and precision in harsh, freezing industrial environments.
● Superb Low-Temperature Resistance: Designed to operate flawlessly and maintain rapid response times in extreme cold environments down to -25°C.
● Double Liquid Junction Design: Features a highly effective dual-junction structure that provides exceptional anti-pollution capabilities, preventing reference poisoning in complex media.
● IP68 Waterproof Rating: Fully submersible and fully protected against water and dust ingress, ensuring safe and continuous online monitoring.
● High Chemical Inertness: Built to resist harsh industrial conditions, ensuring it does not chemically react with strong solvents, acids, or bases.
● Minimal Drift Performance: Delivers outstanding long-term stability with excellent resistance to both time-drift and temperature-drift.
● Robust Sensitive Membrane: Equipped with a highly sturdy, impact-resistant glass membrane that easily withstands mechanical shocks during installation and heavy-duty operation.
LT3900L Low-Temp pH Electrode Customization Capabilities
To meet the diverse demands of different B2B industrial systems, the LT3900L offers highly flexible configuration options:
● Customizable Insertion Depth: The electrode’s insertion depth can be precisely tailored to match your specific pipeline, reactor, or tank dimensions (ranging from 120mm up to 425mm and beyond).
● Upgradable Junctions & Salt Bridges: The standard single-point porous ceramic core can be upgraded to a double-point or triple-point structure. For specialized chemical applications, it can also be customized into a circular PTFE (Teflon) salt bridge.
● Versatile Cable Connectors: We support customization for a wide variety of industrial cable connection formats (including S8, S8M, S7, VP8, K8S, K2, etc.) to integrate seamlessly with your existing transmitters.
● Extended Cable Lengths: To accommodate deep tanks or remote monitoring setups, the transmission cable can be extended up to a maximum of 60 meters without signal degradation.
