The alcohol tester is a device used to detect the alcohol content in human exhaled breath. It is widely used in traffic management, enterprises and institutions, medical institutions, and other fields. Correct usage and precautions are crucial to ensure the accuracy and safety of test results. This article will introduce in detail the precautions for using alcohol testers.
1. Preparation before use
Calibration of alcohol tester: The alcohol tester needs to be calibrated regularly to ensure the accuracy of test results. Calibration can be performed by professional institutions or manufacturers and should be performed in accordance with the instructions for use.
Power supply and battery: Make sure the alcohol tester has enough power or battery power to function properly.
Temperature and humidity: Alcohol testers have certain requirements for ambient temperature and humidity. Before use, you should ensure that the ambient temperature and humidity are within the range required by the equipment.
2. Precautions during use
Avoid smoking, drinking alcoholic beverages, or using alcoholic oral hygiene products before testing to avoid false measurements. In addition, certain medications may affect test results.
Avoid using alcohol testers in unstable environments such as air vents, high temperatures, and high humidity. These conditions may affect the performance of the device and the accuracy of test results.
Testers should operate alcohol testers correctly in accordance with the instructions for use, including starting up, preheating, exhaling and other steps. Only professionally trained and authorized personnel can use alcohol testers, and no unauthorized operation is allowed.
The tester should put his lips close to the exhalation port of the tester, blow hard, and keep exhaling until the tester beeps.
Alcohol testers require regular cleaning and maintenance to maintain the normal working condition of the equipment.
3. Interpretation of results
Threshold setting: Different regions and application fields may have different threshold settings for alcohol content. Testers should understand the relevant regulations in their region or application field.
Judgment of results: Test results are generally expressed in percentage of alcohol content or mg/L. The tester should judge whether the test result is qualified based on the set threshold.
Result error: The test results of the alcohol tester may have certain errors. The tester should understand the error range of the equipment and take appropriate consideration when judging the results. To ensure the accuracy of the results, it is recommended to conduct at least two tests and take the average as the final result.
The correct use and precautions of the alcohol tester are crucial to ensuring the accuracy and safety of the test results. Users should make preparations before use, follow the correct test procedures, and interpret the results according to the equipment requirements. At the same time, compliance with the precautions can ensure the normal operation of the equipment and the confidentiality of test results. Only under the premise of correct use and compliance with the precautions, the alcohol tester can play its due role to ensure traffic safety and healthy life.
