Product Description
DTY-KNY-WL136 Underground Chamber Combustible Gas Monitoring Device
Product Features
The DTY-KNY-WL136 Underground Chamber CombustibleGas Monitoring Device is suitable for environments such asgas valve pits, gas pressure regulating boxes (cabinets), and other underground manholes. It can periodically monitorcombustible gas concentrations in the pipe shaft space, canbe expanded with 1 additional gas type detection channel, andsimultaneously includes 1 gas pressure sensor, 1 water level submersion alarm device, and 1 manhole cover statusdetection alarm device. Monitoring data is uploadedperiodically via a wireless network. This product does notrequire an external power connection, features highintegration, and can operate independently. It automaticallytriggers remote alarms upon detecting events such as excessive gas concentration, over-pressure, high water level,or manhole cover displacement. The product offers stable and reliable performance, with an overall service life of up to 5years.
