It measures pH levels in soil and water applications ranging from 0 to 14 pH, making it widely applicable in industrial environmental sensing scenarios.

Description

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. 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.

Note

If you find white solid granular crystals around the probe shroud, this is a normal situation and please do not worry. It is caused by temperature change, environmental change, or redox during the process of delivery. However, it will not affect the nature of the internal solution and the normal operation of the sensor.
If you find it, please use a wet paper towel to gently wipe off the crystals on it, please do not let it near your children to avoid accidental ingestion.
