Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
The BOQU GPE800 “PH/ORP Sensor Digital pH Sensor Top Brand” is an online digital pH electrode engineered for high-purity and process water measurement. It supports pH 0.0–14.0 and temperature 0–60.0 °C, with pH accuracy ±0.1 and temperature accuracy ±0.5 °C. The sensor is built for continuous online use with robust materials (PPS, PC, PTFE) and low-noise signal transmission.
Product Features
- Polymer-filled reference junction and large-area PTFE diaphragm for a stable reference and diffusion potential.
- Minimal and stable electrolyte bleeding to avoid contaminating ultrapure water.
- Solid dielectric, long diffusion channel and non-blocking junction for extended service life in harsh environments.
- High-quality low-noise cable enabling >20 m signal runs without interference, fast response, good repeatability, and low maintenance.
- Standardized connection (PG13.5) and interchangeable with similar electrodes.
Product Value
The GPE800 delivers reliable, repeatable pH readings in high-purity water systems, minimizing measurement drift and contamination risk. Its long service life and low maintenance requirements reduce total cost of ownership and downtime. Stable long-distance signal transmission simplifies installation and integration into online monitoring systems.
Product Advantages
- Exceptional stability for ultrapure water measurement thanks to polymer-filled junction and PTFE diaphragm design.
- Resistance to fouling and flow-related disturbances, providing consistent readings under varying flow conditions.
- Durable construction and long diffusion channels increase electrode lifetime in demanding environments.
- Low-noise, long cable output and industry-standard fittings allow flexible and interference-free installations.
- Manufactured with lean production for competitive pricing and short lead times, backed by BOQU’s national sales and service network.
Application Scenarios
Ideal for online pH monitoring of ultrapure and process waters—pharmaceutical water systems, semiconductor and electronics rinse/ultrapure water loops, power plant feedwater and boilers, water treatment and reverse osmosis/DI systems, laboratory and industrial process control. Also suitable where long cable runs, low contamination risk and stable long-term performance are required.
