RK500-12 Type-C2 Water pH Sensor（seawater, industrial water）
PRODUCT DESCRIPTION
The RK500-12-C2 stands as a benchmark in pH monitoring technology, engineered to meet the rigorous demands of modern industrial, marine, and environmental applications. This versatile and resilient sensor redefines precision sensing through its advanced material composition—Glass+PC+ABS—and intelligent design, delivering industry-leading performance that prioritizes accuracy, durability, and adaptability for professionals across diverse sectors.
Built to thrive in challenging environments, the C2 operates reliably across a broad temperature range of 0-80°C and withstands pressures up to 1MPa, ensuring stability in high-stress settings. With a rapid 10-second response time (achieving 98% accuracy in flowing liquids), it delivers real-time, actionable data for dynamic monitoring needs. Its robust electrical design features a direct cable connection, while the NPT3/4 threads on both upper and lower ends enable seamless integration into existing systems.

Electrode Maintenance
When the probe is not in use, it can be soaked in 3mol/l KCL solution or saturated KCL solution. It is strictly prohibited to immerse the electrode in distilled water, deionized water, or tap water with very low ion content. If the pH electrode is contaminated with inorganic substances, it can be cleaned with 0.1mol/l HCl or sodium hydroxide solution for a few minutes, and then rinsed with distilled water.If the pH electrode is contaminated with organic matter, it can be cleaned with alcohol or acetone, and then rinsed with distilled water. (Note: When using, remove the protective cap in front of the electrode)
According to the work environment, clean the electrodes with tap water every 3 or 6 months.
