Oxygen alarm is the 1 gas detection equipment specially used to detect the change of oxygen concentration. It can quickly detect the oxygen concentration content in the environment in any scene and anywhere, thus playing an early warning role in the operation safety of dangerous sites and better ensuring the safety of operators. However, we need to make relevant preparations before using the oxygen alarm for detection. Only when we have done these preparations can we make the oxygen alarm more effective. Do you know what you need to do to prepare oxygen alarms before testing? The following is an introduction by Yiyuntian:

1. Check whether the oxygen alarm shell is damaged or damaged, whether the back cover is tight, whether the screws are short or loose, and whether other parts are complete.

2. Check the degree of the oxygen alarm to see if the digital display is at zero or within the allowable error range. If the deviation is too large, the indicated value requires zero calibration.

3. Pay attention to the measurement range of the oxygen alarm and do not use it in an environment where the concentration exceeds the measurement range. This will not only damage the instrument, but also cause danger due to incorrect detection.

4. Before testing, the oxygen alarm should always check the service life of the oxygen alarm sensor and replace it in time if it expires, because it cannot achieve accurate testing function.

5. Before the oxygen alarm is tested, it is necessary to check its power supply, turn on the instrument switch, check whether there is an undervoltage indicator, check the battery voltage, and check whether the power supply is sufficient to work.

To sum up, there are some preparations that need to be made before the oxygen alarm is tested. The oxygen alarm has high stability, convenient installation and maintenance, which can better meet the requirements of high reliability of industrial field safety monitoring equipment, so it can be widely used in indoor chemical products workshop, chemical products and drug warehouse, cable and cosmetics factory, Food factory, winery, laboratory, coal mine, substation and other places.
