ZONEWU Multi Parameter Intelligent Industrial Air Quality Monitor Wall Mounted 0-100ppm RS485 H2S Gas Detector

ZONEWU Multi Parameter Intelligent Industrial Air Quality Monitor Wall Mounted 0-100ppm RS485 H2S Gas Detector

Product Introduction:

In high-risk workplaces such as petrochemicals, wastewater treatment, mining and metallurgy, hydrogen sulfide (H ₂ S) is known as the "invisible killer" - it is extremely toxic, spreads rapidly, and even at extremely low concentrations, it may pose a serious threat to personnel safety and equipment operation. In response to this stringent monitoring requirement, we have launched the RS485 hydrogen sulfide sensor, which uses high-performance electrochemical detection principles to integrate precise sensing with industrial grade reliability.

Core advantages:

1.High sensitivity electrochemical detection

• Using imported grade electrochemical sensing elements, it responds quickly to hydrogen sulfide (H ₂ S) and can usually reflect concentration changes within seconds.
• High measurement accuracy, with an error controlled within ± 3%, can accurately capture ppm level trace gas leaks.

2.Standard RS485 digital output

• Equipped with RS485 communication interface, supporting standard Modbus RTU protocol, compatible with mainstream industrial control devices such as PLC, DCS, touch screen, etc.
• Strong anti-interference ability, with a theoretical transmission distance of up to 1200 meters, suitable for long-distance networking and centralized data monitoring.

3.Wide temperature, wide pressure and protection design

• The working temperature range is -20 ℃ to 50 ℃, and some models can be extended to -40 ℃ to 85 ℃, suitable for cold or high temperature environments.
• It has a protection level of IP65 or above, and is dustproof, waterproof, and salt spray resistant, meeting harsh working conditions such as humidity, dust, and corrosive gases.

4.Stable and reliable circuit protection

• Built in anti reverse, anti overvoltage, and anti lightning protection circuits to prevent damage caused by misconnected wires or voltage fluctuations.
• Long term operation with minimal drift, equipped with automatic zero calibration function, reducing manual maintenance frequency.
