QB2000N Fixed Oxygen Gas Measurement Device with 4-20mAh or RS485 Output
Fixed Oxygen Gas Measurement Device product description
QB2000N is Industrial grade LCD/LED gas leack detector, with 4-20 mA or RS485 ModBus RTU outputproportional to the gas leakage concentration with original imported electro-chemical sensor. It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
The online gas detector monitors gas leakage by natural diffusion.It can be directly connected with DCS systems or Central unit. With relay output, once the concentration exceed the preset alarm point(threshold), it will start the acoustic-optical alarm on the central unit and drive the external equipment like exhaust fans.
Fixed Oxygen Gas Measurement Device product features
- Changable Sensor mould
