Can provide different materials and connection mode, can be widely used in steam system and other industrial liquid system.The steam trap can be tested to see if it is working properly by placing an observation mirror firmly downstream of the steam trap.When several traps are centrally discharged into a closed condensate recovery system, an observation mirror can be conveniently used to check the operation of each trap.

In addition, the observation glass can provide information about other aspects of the steam system.For example, if the mirror glass has the same body sediment and becomes blurred, it can be determined that the steam contains free oxygen and carbon dioxide, which causes the corrosion of the condensation pipe, and it can also be determined that the boiler precipitates organic matter in the water.
