Frequently Asked Questions (FAQs) About the RK500-12 pH Sensor

Q: Can the RK500-12 be used with seawater?
A: Yes, it can. For seawater applications, we recommend choosing a model utilizing the Glass/PC/ABS/316L material combination (such as the B3 model which uses Glass+316L), which offers excellent resistance to saltwater corrosion.

Q: What is the maximum temperature this sensor can withstand?
A: Models employing the Glass+PPS/ABS/PC material combination are designed to operate effectively in environments with temperatures exceeding 80 degrees Celsius (> 80℃).

Q: Should I choose PC+ABS or Glass+ABS for general water applications?
A: Both materials perform well in general water. However, Glass+ABS (such as the B2 model) may offer slightly greater rigidity and scratch resistance at the sensor tip. On the other hand, PC+ABS (such as the A1 model) emphasizes cost-effectiveness and material toughness. You can consult with the RIKA team to select the most appropriate model for your needs.
