Product Overview
An IP68 RS485 pH Sensor ranges – from 0 to 14 pH. Used in soil and water applications like gardening, and swimming pools. Use the sensor with SenseCAP Data Logger for seamless data collection and management.
It measures pH levels in soil and water applications ranging from 0 to 14 pH, making it widely applicable in industrial environmental sensing scenarios. Note: We have two versions of the Industrial pH Sensor. The main difference is the cable connector. Please choose the version that best suits your needs: This one is with hook-up wires. It is compatible with SenseCAP LoRaWAN® Data Logger to connect with the LoRaWAN® network, enjoying the benefits of low-power and long-range communication. Another version is with a waterproof aviation connector. It is compatible with SenseCAP Sensor Hub 4G Data Logger , which can collect various sensor data simultaneously and send them via 3G/4G LTE. High Performance: High accuracy, fast response, good repeatability Universal Protocol: MODBUS-RTU RS485 and 0~2V Analog Voltage Wide-range Power Supply: Can be powered with supply voltage within 3.6V ~ 30V Strong Robustness: Suitable to be immersed in soil or water for a long time, anti-corrosion Maintainance-Free: A unique junction efficiently improves the problem of junction clogging This pH Sensor with hook-up wires measures the hydrogen-ion activity in water-based solutions, indicating its acidity or basicity expressed as pH. pH level is an important indicator in many scenarios, especially in monitoring soil conditions and water quality. This pH Sensor is designed with industry standards. It adopts international advanced solid dielectric and large-area polytetrafluoroethylene liquid junction, which is not easy to block and convenient for maintenance. Its electrode is IP68, the transmitter is IP65 rated, waterproof in a tight seal, and capable of withstanding long-term constant use in professional scenarios.
