There're a lot of hydrogen gas produced in the battery room.
But hydrogen gas leak should be controller for safety.
Hydrogen gas transmitter is used to monitor the concentration of hydrogen.
Hydrogen gas transmitter can sound an alarm by visual and audible signals to operators in
the area where the leak is occurring, giving them the opportunity to leave.
It is important because there are many gases that can be harmful to
organic life, such as humans or animals.
- QB2000 is afixed gas detecting transmitter.Whichprovides4-20 mA outputand RS485ModBus RTU outputproportional to the gas concentrationwith
electrochemical sensor, which is flexible, durable, swift and etc.
and can be directly connected with DCS systems.It has been widely
used in petrol, chemistry, metallurgy, artifice, gas
transportation, biological medicine and water procession etc to
test multi-gas, such as flammable gas and toxic gas
◆Sensor types:electrochemical sensor

system and RS485 ModBusoutput
◆Sensormodule design on -spot replacement s and automatically
distinguish sensor fault and current display fault simultaneously.
◆LED Display(LCD optional)
◆Password verification for repeat operation, avoid fault
◆-40～+70℃ following compensationfor accurate detecting.
◆Second grade visual alarms on-site and Relay(connected with
audible/visual alarms or drive exhaust device).
