Industry Online NH4-N Transmitter For Sewage Monitoring


Industry Online NH4-N Transmitter For Sewage Monitoring


The ammonia nitrogen water quality analyzer is specially designed for the water quality analysis of urban and industrial sewage, drinking water, rivers, and groundwater. Using the latest electrochemical analysis technology (ion selective electrode), based on the unique compensation curve obtained from a large number of on-site research data analysis, the introduction of multi-parameter automatic compensation can quickly and accurately measure the ammonia nitrogen concentration in the water to achieve continuous measurement and long-term reliable operation.

FAQ
1. Which sensors can be connected to your NH4-N controller?
A: The NH4-N meter can be compatible with DRFN digital NH4-N sensors.

2. How does your NH4-N controller collect sensor data?
A: The connected sensor uploads the detected data in a special encrypted communication method to ensure that the controller can collect high-precision data more stably


3. Does the NH4-N controller have an ambient temperature alarm function?
Our NH4-N controller has ambient temperature alarm function


4: The NH-N controller with RS485 modbus RTU?

NH4-N controller with RS485 Modbus RTU, RS485 Modbus RTU provides a stable and reliable communication solution suitable for industrial environments, enabling different types of equipment to communicate and control each other, which is beneficial to the integration and management of industrial automation systems.

RS485 allows multiple devices to be connected to the same bus and perform data transmission and control through serial communication protocols, making the integration between devices simpler and more flexible.

RS485 uses differential signal transmission, which can resist electromagnetic interference in industrial environments and ensure stable data transmission.

RS485 can support relatively long communication distances, allowing devices to be distributed in distant locations while maintaining reliable communication.

Modbus RTU is a widely used communication protocol. Its standardization allows devices from different manufacturers to communicate with each other, increasing the interoperability and compatibility of the devices.
