    Industrial pH Sensor MODBUS-RTU RS485 & 0-2V Analog Voltage (S-pH-01B), with waterproof aviation connector
    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 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.
    • Another version 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.

    Features

    • 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
        

    Description

    This pH Sensor with a waterproof aviation connector 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. This pH Sensor comes with a MODBUS-RTU RS485 serial communications protocol and 0~2V Analog Voltage output. It can be easily connected and integrated with other devices such as data loggers, Converter, displays, etc. This cost-effective pH sensor features low-power consumption, compact size, portability, and high integration.

    FAQ

    Q: Is it factory calibrated? How to calibrate?
    A:

    Yes, the device is fully calibrated prior to shipment from the factory.

    About calibration, please refer to the document:

    https://raw.githubusercontent.com/Jenkinlu001/SenseCAP/master/PH10-AppNote-PH%20Calibration%20by%20Modbus%20Command.doc



     
    Q: Why is the temperature output from the sensor inaccurate?
    A: PH electrode itself has no temperature sensor, the temperature is the plate temperature sensor; If necessary, you can access the NTC (10K, 3950) thermistor temperature sensor.


     
    Q: Can the sensor be used in soil? How to install?
    A:

    Yes, Yes, the principle is still to measure the pH in the soil moisture, so it will be affected by the soil moisture, and the drier the soil, the greater the error.

    Installation method: Dig out a pit, fill the pit with some water, stir the soil into a slurry, and then place the sensor glass probe. Be careful not to overexert yourself and avoid hard objects such as stones, otherwise the probe will be damaged.
