LT3100 Anti-Clogging Sewage pH Sensor with PTFE Ring Junction

High-stability YB3100 industrial pH sensor from a leading Chinese manufacturer, offering long-life monitoring for harsh wastewater and sewage treatment.

● Non-Stick PTFE Junction: Large annular Teflon (PTFE) liquid junction resists oil adhesion and prevents solid particles from blocking the sensor.
● Double-Junction Reference: Provides an extra barrier against chemical poisoning from sulfides, cyanides, and heavy metals in industrial effluent.
● Solid Polymer Electrolyte: Eliminates the risk of electrolyte leakage and ensures stable performance under high-pressure conditions (up to 0.6MPa).
● Impact-Resistant ABS glass fiber shell: Robust 3/4″ NPT threading and chemical-resistant body designed for direct immersion or pipe mounting.

YB3100 Heavy-Duty Sewage pH Probe Overview

As a professional pH sensor manufacturer, LOOTEST supplies the ABS Glass Fiber LT3100 pH Electrode for Industrial Wastewater. This industrial-grade probe features a unique long-path reference system, providing exceptional stability and an extended service life while remaining cost-effective. Designed for heavy-duty applications like municipal sewage and chemical processing, its robust sensitive bulb resists mechanical impact. Our factory offers OEM customization, including PPS material upgrades and cable lengths up to 60m, ensuring this sensor meets specific project requirements for global distributors and water treatment companies.
