The RK500-12-A2 is a state-of-the-art pH monitoring solution engineered to excel in demanding industrial, marine, and environmental applications. Designed with versatility and durability in mind, this sensor combines cutting-edge materialsincluding a robust Glass+PC+ABS constructionwith intelligent design to deliver unmatched precision and reliability in even the harshest environments.
Capable of operating across a wide temperature range (0-80°C) and handling pressures up to 0.8MPa, the RK500-12-A2 is built to withstand challenging conditions while maintaining exceptional performance. Its intelligent features include thermal resistance-based temperature compensation, ensuring accurate readings regardless of fluctuations, while its 0.01pH resolution and matching accuracy make it ideal for applications where precision is non-negotiable. With a rapid 10-second response time (98% for flowing liquids), this sensor delivers real-time data critical for responsive monitoring systems.
