DFRobot Gravity Analogue ORP Sensor for Arduino
Only 3 pieces in stock at third-party supplier
Product details
With this ORP sensor, you can easily measure the chlorine content in your pool. It is important to note that an ORP or REDOX sensor measures the oxidation or reaction potential of chlorine with water and expresses this as a voltage (mV). This differs from an amperometric chlorine sensor, which indicates the chlorine level in parts per million (ppm). The sensor compares the REDOX potential of the pool with a stable reference solution, so it does not need to be calibrated by the end user. However, if you are unsure about the measurement, you can verify it with an ORP standard solution and adjust it if necessary or compare it with a chlorine test strip.
