oxygen detector is the 1 gas alarm instrument mainly used to detect the change of oxygen concentration at present. it can display real-time concentration, alarm, time, temperature, humidity, storage, communication, electricity, charging state, concentration unit, gas molecular formula, gas name and other information, and is mainly used to detect the oxygen concentration content in areas with poor ventilation conditions such as confined spaces, underground and mine passages, therefore, the application is more extensive. Do you know how to use oxygen detector ? The following is a brief introduction by Yiyuntian:

How to use the oxygen detector:

1. Power on:

Press the left" power "key for a few seconds to start the oxygen detector, the display screen lights up, the self-check is automatically carried out after the preheating is completed, the alarm indicator lights up, the buzzer sounds, and the alarm stops automatically after the self-check is completed.

2. Test:

Hand the portable oxygen detector into the area to be tested or use a back clip, the display screen of the oxygen detector will automatically display the oxygen concentration value detected in the current area.

3. Alarm:

When it is detected that the oxygen content in the area reaches the preset alarm value, the normal oxygen concentration in general air is 20.9 %VOL, and the detection value is lower than 19.5 %VOL, or higher than 23 % VOL will trigger the alarm of the oxygen detector, such as vibration, flashing alarm indicator and buzzer.

4, silencing:

When the oxygen detector alarms because it detects that the oxygen concentration exceeds the limit, staff can press the "shutdown" button to turn off the alarm.

5. Shut down:

When the oxygen detector is turned on, press the "Shut Down" key for a few seconds to shut down the oxygen detector.

In summary, it is how to use the oxygen detector. It is worth noting that after starting up, we must ensure that the oxygen concentration value displayed by the oxygen detector under normal air conditions is 20.9 % vol. Otherwise, if the actual value difference is too large or the instrument is used more frequently, the oxygen detector should be verified first to ensure its accuracy and validity.
