RK500-12 Type-A2 pH Meter Sensor（seawater, industrial water）
PRODUCT DESCRIPTION
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 materials—including a robust Glass+PC+ABS construction—with 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.

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.
