In some places where gas is frequently produced, some uncertain factors such as high gas concentration may lead to danger. Therefore, in some workplaces, gas testers are often used to detect gas all the time. The gas tester is the 1 kind of gas leakage concentration detection of instrumentation tools, the main use of gas sensors to detect the presence of gas types in the environment. Do you know how to use gas tester ? The following is a brief introduction by yi yun Tian:

How to use the gas tester:

1, carefully read the operation instructions corresponding to the gas tester before operation, familiar with the performance and operation of the machine.

2. Check whether the battery power is sufficient. If the battery power is insufficient, replace the battery in time.

3. Check whether the air filter at the air inlet is blocked by foreign matters. If the air filter is blocked, clean it up or replace it.

4. during the self-checking during startup, listen to whether the graded alarm sound and light alarm and vibration alarm are accurate. if they do not meet the requirements, they are not allowed to be used and should be revised immediately.

5, press the start key for three seconds during startup, enter the self-check state, and observe whether the low alarm value and high alarm value set by the detector are accurately set (CO detector level 1 alarm 50ppm, level 2 alarm 100ppm; Oxygen detector level alarm reported 19.5, oxygen detector level 1 alarm reported, level 2 alarm reports 22%; Level 1 alarm of hydrogen sulfide detector 10 Ppm, secondary alarm 15ppm), such as not required setting is not allowed to use, and should be revised immediately. During the self-check during startup, listen to whether the graded alarm sound and light alarm and vibration alarm are accurate. If the setting does not meet the requirements, it is not allowed to be used and should be revised immediately.

6. observe whether the initial value is accurate after starting up under fresh air conditions (CO detector initially displays 0 ppm;O2 detector initially displays 20.9; Hydrogen sulfide detector initially displays 0 Pmb), if the display value is not accurate, it is strictly prohibited to use, should be revised immediately.

during 2. use

should be worn as close to the mouth, nose parts, such as the front neckline of clothes, jacket pocket, etc., it is strictly prohibited to place the alarm in the pocket and other parts that are not easy to view, which will affect the detection value.

2. Collisions should be avoided during use, resulting in abnormal detection data.

3. components such as gas tester sensors are precision components. do not open the cover of the adjusted instrument casually. pay attention to waterproof and impurity entry during use to prevent data abnormality.

4. if there are abnormal situations such as continuous flashing of indicator light, sudden no numerical display on the display screen, no movement of numerical display in the area where the gas obviously exceeds the standard, and large gap, the operation should be stopped immediately, and the problem should be observed by evacuating to the fresh air area, and timely exclusion, otherwise it is strictly prohibited to continue to use.

after 3. use

‍

1. After the gas tester is used, press and hold the shutdown key. The display screen shows a 5-second countdown. After the countdown ends, the LCD displays "off", and then the instrument does not display, instrument shutdown, it is strictly prohibited to directly deduct the battery forced shutdown.

2. After the gas tester is turned off, clean the dust attached to the surface and clean the equipment.

3. When the gas tester is not working for a long time, it should be turned off and placed in a dry, dust-free environment that meets the storage temperature.

4. the gas tester shall be specially managed to prevent the loss of equipment and affect normal use.

In summary, it is how to use the gas tester. In order to ensure safety, we must carry out safety confirmation before entering the working area, and make corresponding safety protection, such as masks, gas masks, etc. (see the specific scene of use), and at the same time, we should confirm the safety of testing personnel and prevent potential safety hazards before entering the working surface for detection.
