YCLH Sensor
1 / 5
Wastewater treatment plants and confined spaces: For continuous monitoring of hazardous H₂S gas and oxygen deficiency to ensure personnel safety.
Industrial basements, pump stations, and utility tunnels: For early detection of toxic gas accumulation and environmental condition monitoring.
Chemical storage areas and industrial workshops: To ensure workplace safety by monitoring oxygen levels and potential H₂S leaks from processes.

This multi-functional sensor monitors Oxygen (O₂), Hydrogen Sulfide (H₂S), Temperature, Humidity, and Dew Point simultaneously.
The Oxygen (O₂) measurement range is 0-25%vol with a resolution of 0.01%vol. The Hydrogen Sulfide (H₂S) measurement range is 0-100ppm with a resolution of 0.1ppm.
The sensor supports multiple protocols including Modbus TCP, UDP, SNMP (V1.V2), and MQTT via an RJ45 interface.
Yes, the device supports both DC12～48V power supply and standard POE (Power over Ethernet) power supply.
The sensor is equipped with light, sound, email alarms, and protocol alerts to ensure immediate warning of hazardous conditions.
The sensor features data storage capability that can store up to 100,000 historical records.
