Oxygen sensor (O2 sensor) for monitoring air quality
The O2 sensor response quickly to the changes in oxygen concentration with strong anti-interference ability. The oxygen sensor works well in harsh and complex environments with a wall-mounted waterproof case and analyzes the concentration of O2 accurately. The measurement accuracy is up to ±3% F.S; the range is 0-25% VOL. It supports standard Modbus-RTU with RS-485. In severe weather such as dust, rain and snow, the device can also work normally.
