Ph Sensor by BOQU

Product Overview

1) Product overview

Product Features

- Ph Sensor by BOQU (models shown: PH8022 / PH8000 Ultra?Pure Water pH Electrode) is a specialized pH electrode designed for measuring high?purity and ultra?pure water.

Product Value

- Measurement ranges: pH 0.0–14.0 and temperature 0–60.0 °C. Reported accuracies: pH ±0.1, temperature ±0.5 °C; slope ≥96%. Temperature compensation options: 10K, 2.252K, PT100, PT1000.

Product Advantages

- Built for online/process use with threaded housing (upper and lower 3/4 NPT), chemically resistant materials (PPS, PC, PTFE) and a low?noise cable capable of >20 m signal runs.

Application Scenarios

2) Product features

- Polymer?filled reference junction and large?area PTFE diaphragm produce a stable reference potential and stable diffusion potential.

- Design keeps the reference diaphragm distance to the glass sensor small and constant for fast, reliable circuit formation and rapid response.

- Minimal, stable overflowing electrolyte prevents contamination of measured pure water.

- Solid dielectric and long diffusion channel reduce clogging and extend electrode life in harsh environments.

- Low?noise cable for long, interference?free signal runs; simple maintenance with little need for additional dielectric.

3) Product value

- Delivers accurate, repeatable pH readings in very low?ion/high?purity water where conventional electrodes can fail.

- Minimizes risk of contaminating ultrapure water, preserving process/product quality in sensitive applications.

- Long service life and low maintenance lower total cost of ownership and reduce downtime for industrial and laboratory processes.

- Fast response and stable readings improve process control and monitoring reliability.

4) Product advantages

- Engineered specifically for ultra?pure water measurement (stable reference, low diffusion error).

- Robust construction with chemically resistant housings (PPS/PC/PTFE) suitable for demanding environments.

- Long cable with low noise ensures flexible, remote installations without signal degradation.

- Easy maintenance and compatibility — can be replaced with similar electrodes from other manufacturers.

- Backed by BOQU’s quality management, customization options, and customer support.

5) Application scenarios

- Online pH monitoring of ultra?pure/high?purity water systems (e.g., water for injection, laboratory-grade water).

- Semiconductor and electronics manufacturing where trace?ion control is critical.

- Pharmaceutical and biotech processes requiring uncontaminated ultrapure water.

- Power plant condensate and boiler feedwater monitoring, chemical process control, and other industrial applications needing stable pH measurements in low?ion media.

- Research laboratories and any application that needs accurate, low?contamination pH measurement with long?term stability.
