Aquaculture：Maintain optimal water quality for fish, shrimp, and recirculating systems (e.g., a Southeast Asian shrimp farm improved survival rate by 25% with this probe.
Industrial Processes：Ensure consistency in chemical manufacturing, food & beverage, and pharmaceutical applications.
Environmental Monitoring：Track pH in surface water, groundwater, and soil for ecological research.
Laboratory & R&D：Reliable measurements for buffer solutions, corrosion testing, and academic experiments.

Success Stories

European Chemical Manufacturer Enhances Process Consistency

A leading Western European chemical company reduced batch rejection rates by 30% after deploying the WHPH-768 Probe for real-time ±0.05pH monitoring in production reactors.

Southeast Asian Shrimp Farm Improves Survival Rates

The WHPH-768’s automatic temperature compensation helped an aquaculture operation stabilize pH levels, increasing shrimp survival rates by 25% and boosting yields.

North American Wastewater Plant Meets Regulatory Standards

By integrating the IP68-rated WHPH-768 Probe via MODBUS RS485, a wastewater plant achieved 100% compliance with discharge regulations, avoiding costly fines.

Installation & Maintenance Guide ：Installation Diagram

Install in a bypass line parallel to the main flow for continuous monitoring without downtime. Maintain a constant flow rate of 250–500 mL/min using a control valve; mount vertically for full submersion.

Maintenance Tips

Routine Cleaning：Soak the glass bulb in 0.1M HCl for 10–15 minutes to dissolve deposits, then rinse with DI water.
Proper Storage：Store in 3.3M KCl solution; never leave in distilled water or protein-rich liquids.
Calibration Schedule：Calibrate every 2–4 weeks for industrial use; monthly checks may suffice in stable environments.

Why Choose the WHPH-768?

Trusted Precision：±05pH accuracy meets the strictest quality standards.
Rugged Durability：IP68 rating and chemical-resistant materials ensure long-term performance in harsh conditions.
Plug-and-Play Integration：MODBUS RS485 output for seamless connectivity with existing monitoring systems.
Low TCO：Minimal maintenance and calibration reduce operational costs.

FAQs

Q：Can the sensor cable be extended?

A：Yes,ensure proper grounding to minimize interference.

Q：How to handle electrode fouling in oily samples?

A：Gently scrub the bulb with 0.1M HCl and a soft brush before soaking to remove oil-based residues (avoid silicone grease).

Q：Does it include temperature compensation?

A：Yes, automatic temperature compensation (0–80°C) ensures accurate pH readings across all operating temperatures.
