Inquiry about the calibration of redox probes for the Pool Basic Double Evo system.

Customer:
Hello. My name is Rosa and I want to buy a redox probe (chlorine) for my Pool Basic Double Evo system. I would like to know if the probes come pre-calibrated or if I need to calibrate them before installing. Thank you very much in advance.

Technical Advisor:
Hello Rosa, thank you for your inquiry. The redox probes we sell for the Pool Basic Double Evo system come pre-calibrated from the factory, so you don't need to calibrate them before installing. However, it is recommended to perform periodic checks to ensure that the calibration remains accurate. Here is the link to our calibration instructions: http://www.example.com/calibration.
