FAQ:
1: Which should be adjusted first, pH or EC?
Usually adjust pH first, then EC. As pH adjustment will affect EC, while EC adjustment has less impact on pH.
2: Can multiple tanks be monitored simultaneously?
Yes. Install one sensor in each tank and connect them to data logger via RS485.
3: How long does the online pH sensor electrode last?
Usually 6-12 months. Approximately 6-9 months in nutrient solution environment, and over 12 months in clean water.
4: Is customization supported?
Yes. Please tell us electrode length, mounting thread, output signal, measurement range, etc. you’d like to customize.
