The sensor's isolated power design minimizes electrical noise, ensuring stable data transmission in environments with strong electromagnetic interference.
Supports automatic or manual temperature compensation to maintain accuracy across varying operating conditions (0–60°C).
Calibrate effortlessly using USA, NIST, or custom pH/ORP solutions for tailored measurement scenarios.
The smooth, flat surface prevents air bubble accumulation and simplifies cleaning, reducing maintenance downtime.
A single salt bridge with a ceramic sand core ensures consistent electrolyte flow and long-term measurement stability.
Constructed from corrosion-resistant polymer plastic, the sensor withstands harsh chemicals and physical stress while occupying minimal space.
Monitor pH levels in real time to optimize neutralization, coagulation, and disinfection processes.
Deploy in rivers, lakes, or reservoirs to track acidity changes caused by pollution or natural factors.
Maintain optimal pH for aquatic life health and prevent stress or mortality in fish and shrimp farms.
Integrate into chemical manufacturing, pharmaceuticals, or food production to ensure compliance with quality standards.
Deliver precise pH data for scientific studies on water chemistry, soil analysis, or biological systems.
Manage nutrient solutions and irrigation water to enhance crop growth and yield.
