SUP-PH5018 Glass Electrode pH Sensor, Water pH Sensor for Industrial/Laboratory Use
Introduction
The SUP 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
Maintenance-Free Design: Achieves lasting stability and minimal maintenance by adopting internationally leading solid dielectric and large-area PTFE liquid junction designs.
Clog-Free Operation: Effectively solves the problem of electrode clogging and requires no supplementary dielectric.
Extended Electrode Life: Features a specially designed long-distance reference diffusion path to guarantee extended electrode life in aggressive environments such as sewage and corrosive media.
II. Installation and Cost Efficiency
Simplified Installation: Utilizes a durable PPS/PC shell and upper/lower 3/4NPT pipe threads for quick installation.
Cost Saving: Allows for side or vertical installation onto reaction vessels or pipes without the need for an external protective sheath, which significantly simplifies the process and reduces costs.
III. Measurement Performance
High Accuracy: Provides high accuracy, fast response, and good repeatability for reliable data.
Stable Reference: Relies on a stable silver ion Ag/AgCL reference electrode to maintain 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.
