Product Applications
Accurate detection: Using advanced electrochemical principles, the concentration of sulfur dioxide can be determined accurately, and the data error is extremely small.
Communication is convenient: it supports RS485 communication and the standard ModBus RTU protocol, making it easy to network with various devices and ensuring stable data transmission.
Flexible settings: The communication address and baud rate can be set independently, and it can be adapted to different application environments and system requirements.
Power supply: 10-30V wide voltage input, no need to worry about voltage fluctuations, can work normally under different power conditions.
Strong and durable: The high-protection shell is waterproof, dust and impact resistant, and is adapted to harsh scenarios such as high temperature, humidity, and dust.
Agile response: When monitoring, the response is rapid, and once the concentration of sulfur dioxide in the environment changes, the data can be quickly responded to and fed back.
