PH5018 Glass Electrode pH Sensor, Water pH Sensor for Industrial/Laboratory Use
Introduction
This remarkable electronic pH sensor probe is a high-performance, low-maintenance glass pH sensor specifically engineered to handle harsh industrial environments. This pH sensor electrode utilizes innovative solid dielectric and a large-area PTFE liquid junction technology to effectively overcome the common industrial pain points of electrode clogging and frequent maintenance.
This water pH sensor offers superior anti-interference capability and long-term stability, making it suitable for industrial processes like chemical production, wastewater treatment, petrochemicals, and mining, where high measurement precision and extended electrode life are critical.
Feature
I. Durability and Low Maintenance
The sensor features a maintenance-free design using advanced solid dielectric and a large-area PTFE liquid junction for lasting stability and minimal upkeep.
It prevents clogging without a supplementary dielectric, while a long-distance reference diffusion path extends electrode life in aggressive environments like sewage or corrosive media.
II. Installation and Cost Efficiency
The sensor provides simplified installation through a durable PPS/PC shell and upper/lower 3/4NPT pipe threads for fast setup.
It cuts costs by enabling side or vertical mounting directly on reaction vessels or pipes, avoiding the need for an external protective sheath to streamline the process and reduce expenses.
III. Measurement Performance
The sensor delivers high accuracy, fast response, and good repeatability for dependable data, while relying on a stable silver ion Ag/AgCL reference electrode to uphold measurement integrity.
IV. Signal Transmission
- Long-Distance Transmission: Includes a high-quality, low-noise cable that effectively resists interference.
- Wiring Flexibility: Supports ultra-long signal transmission greater than 40 meters, offering great flexibility for field wiring.
