In agricultural non-point source pollution monitoring, drinking water safety assurance, and surface water environment monitoring, nitrate ion concentration is the core indicator for measuring the health of water bodies. This sensor is based on high-precision ion selective electrode technology and intelligent IoT transmission scheme, which can achieve long-term stable monitoring under wide temperature and pressure conditions, providing real-time and reliable data support for fields such as environmental protection, water management, and aquaculture.
Core advantages of the product:
1.Wide range and high precision, suitable for multiple scenarios
We offer two range options, 0~100.0 mg/L and 0~1000.0 mg/L, with a resolution of 0.1 mg/L and measurement accuracy better than ± 5% or ± 2 mg/L (whichever is higher). Whether it is trace pollution in drinking water sources or high concentration discharge of industrial wastewater, it can accurately capture changes in nitrate concentration and meet different monitoring standards requirements.
2.Intelligent temperature compensation, real and reliable data
Built in Pt1000 high-precision temperature sensor, supporting automatic temperature compensation, effectively eliminating the influence of environmental temperature fluctuations on measurement results. The temperature measurement resolution is 0.1 ℃, with an accuracy of ± 0.5 ℃, ensuring that the sensor maintains stable output under working conditions of 0-40 ℃ and ≤ 0.2MPa.
3.Flexible power supply design, suitable for field deployment
Supports DC 10~28V wide voltage input, rated voltage 12VDC, compatible with multiple power supply methods such as solar panels and batteries. The standard DC 5.5mm × 2.1mm interface facilitates quick on-site wiring and significantly reduces the deployment difficulty of unmanned stations.
4.Multi band LoRa communication, building a wide area monitoring network
Supports global mainstream LoRaWAN frequency bands such as CN470/IN865/EU868/US915, with optional OTAA Class A/C working mode, default reporting cycle of 10 minutes, and flexible configuration. By combining the LoRa TDMA networking protocol, stable data transmission with low power consumption, long distance, and multiple nodes can be achieved, making it easy to build a large-scale water quality monitoring network.
5.Electrode has a long lifespan and low maintenance costs
The electrode core components are designed to have a lifespan of up to 1-2 years and come standard with 5-meter cables (length can be customized), reducing the maintenance burden caused by frequent replacement. Combined with IP68 protection structure, it can work continuously submerged in water for a long time, suitable for complex environments such as rivers, reservoirs, and aquaculture ponds.
