About the Product
Description:
This industrial pH Sensor measures pH levels in soil and water applications ranging from 0 to 14 pH, making it widely applicable in industrial environmental sensing scenarios (e.g. gardening, swimming pools, etc.). Use the sensor with SenseCAP Data Logger for seamless data collection and management.
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 an 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, converters, displays, etc. This cost-effective pH sensor features low-power consumption, compact size, portability, and high integration.
Features:
High Performance: High accuracy, fast response, good repeatability
Universal Protocol: MODBUS-RTU RS485 and 0~2V Analog Voltage

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: raw.githubusercontent.com
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.
