5 FAQ
Q: Can this measure ultra-pure water conductivity?
A: This model is optimized for general water quality. For ultra-pure water, a specialized low conductivity sensor is needed.
Q: What is the warranty period for this module?
A: We provide a 12-month manufacturer warranty covering defects in materials and workmanship.
Q: How often does the sensor require calibration?
A: Calibration frequency depends on usage environment, but typically every 3-6 months is recommended.
Q: What is the maximum cable extension length?
A: You can extend up to 1000 meters using proper shielded twisted pair cable.
Q: Is this compatible with Arduino boards?
A: Yes, it is compatible when used with an RS485 to TTL shield or converter module.
