BTMETER 5800H Portable Ultrasonic Oxygen Detector User Manual

1. Product Overview

The 5800H handheld ultrasonic oxygen detector utilizes the principle of ultrasonic waves to accurately measure the concentration, flow rate, and pressure of oxygen in gas. It is specifically designed for use with PSA oxygen generators and concentrators. The device integrates a high-precision pressure sensor to detect the oxygen outlet pressure.

This 3-in-1 gas meter is a professional tool for simultaneously measuring oxygen concentration, flow rate, and pressure, making it ideal for both medical and industrial oxygen systems.

4. Operating Instructions

4.1 Power On/Off

Press the ON button to turn on the device. The LCD display will light up and show the initial readings.
Press the OFF button to shut down the device.

4.2 Measuring Flow Rate and Oxygen Concentration

Insert the provided hose into the "Conc/flow" input port on the top of the detector.
Connect the other end of the hose to the oxygen source (e.g., PSA oxygen generator outlet).
Press the ON button to start measuring. The display will show the oxygen purity and flow rate.

4.3 Measuring Pressure

Insert the provided hose into the "Pressure" input port on the top of the detector.
Connect the other end of the hose to the point where pressure needs to be measured.
Press the ON button to start measuring. The display will show the pressure reading.

4.4 Backlight Function

Press the backlight button (light bulb icon) to turn on the LCD backlight.
Press the backlight button again to turn off the backlight.

4.5 Data Hold Function

Press the HOLD button to freeze the current data on the display. An 'H' symbol will appear on the screen.
Press the HOLD button again to release the data hold and resume live measurements.

4.6 Automatic Shutdown

In the oxygen measurement state, if there is no operation or data input for 5 minutes, the device will automatically shut down to conserve battery. This also applies to the stress test state.
