The calibration process of the oxygen detector is undoubtedly a key part of ensuring its measurement accuracy and reliability. In this process, any minor negligence may lead to the deviation of the measurement results, thus affecting the safety of the whole production process. Therefore, in order to make the oxygen detector provide more accurate and reliable measurement data, and better help enterprises to achieve sustainable, healthy and stable development, we must pay attention to its calibration process. So do you know what the calibration process is for oxygen detector ? The following is an introduction to yiyuntian electronic editor:

Oxygen detector calibration process:

1. Check the instrument:

Before using the oxygen detector, check whether the appearance of the oxygen detector is damaged or worn, check whether the power supply is normal, whether the battery is sufficient, and whether the sensor is clean and free of dust or dirt.

2. Calibrate the instrument:

Use a standard gas (typically a standard gas with an oxygen concentration of 20.9 percent) for calibration. Put the oxygen detector in the standard gas, wait for stability, press the calibration button to enter the calibration mode, adjust the calibration button according to the instructions to make the displayed oxygen concentration the same as the standard gas concentration, and press the confirmation button to exit the calibration mode after completion.

3. Adjust the sensitivity:

Place the oxygen detector in the air, wait for stability, press the sensitivity adjustment button to enter the sensitivity adjustment mode, and adjust the sensitivity adjustment button according to the instructions to make the displayed oxygen concentration match the actual situation, after the adjustment is completed, press the Enter key to exit the sensitivity adjustment mode.

4. Check the response time:

Place the oxygen detector in the standard gas, adjust the oxygen concentration in the gas to different values, record the oxygen concentration displayed by the oxygen detector and the actual oxygen concentration, and calculate the response time. If the response time meets the requirements, it can be used normally; if it does not meet the requirements, it needs to be repaired or replaced.

5. Set reasonable alarm limits:

For the oxygen detector, it is also necessary to set reasonable alarm limits, including the oxygen deficiency alarm setting value is usually set to 19.5 VOL, and the oxygen enrichment alarm setting value is usually set to 23.5 VOL to ensure that the alarm can be triggered in time when the oxygen concentration is too low or too high to prevent personnel health damage.

To sum up, we can see that the calibration process of the oxygen detector includes checking the instrument status, using standard gas for calibration, adjusting the sensitivity and checking the response time. Only in this way can we ensure the accuracy of the oxygen detector, escort for the safety of people's lives.
