RK500-12 Type-D1 pH Sensor for Conventional Water
PRODUCT DESCRIPTION
The RK500-12-D1 represents a sophisticated solution in pH monitoring technology, engineered to meet the rigorous demands of industrial, municipal, and environmental water quality management. Designed for reliability and precision in diverse aqueous environments—from conventional water systems to natural water bodies like rivers—this sensor redefines durability and performance through its advanced material composition and intelligent design.
Crafted with a robust Glass+PC+ABS housing, the RK500-12-D1 ensures long-term stability in challenging conditions, while its IP68 ingress protection rating guarantees complete immunity to dust and submersion in depths up to its operational limits. Operating seamlessly across a 0–60°C temperature range and handling up to 0.6MPa working pressure, it excels in both static and dynamic fluid environments, delivering a rapid 10-second response time (achieving 98% measurement stability in flowing liquids).

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.
