Does this need to be calibrated? If so, how often? My hope is to use it continuously, long-term in hydroponics.

Good afternoon. This measurement system has excellent sensitivity and is designed for continuous use. Like any system for measuring physical variables, it must be calibrated periodically, depending on the conditions of use and the tolerance to error that must be maintained. In hydroponics, the PH level is a critical variable, so we recommend checking the equipment's measurement error level monthly and replacing the probe after a maximum of 18 months.

What is the input voltage?

Hello! There is a lot of information on the internet, for example the attached video https://www.youtube.com/watch?v=zUEl3Y3yKL4 We hope it will serve as a guide. If it is not enough, do not hesitate to contact us. Thank you!
