Troubleshooting and Maintenance of Medical Oxygen Analyzer

An oxygen analyzer is a precision instrument that can detect the concentration of oxygen gas. The accuracy of on-site gas concentration detection directly determines the quality and price of the equipment. So, how can we troubleshoot and solve the problem when the purchased instrument shows significant errors?

  1. We know that the longer the gas detection sensor is used or the more frequently the measured gas appears, it may cause linear attenuation of the sensor in a high-temperature and high-humidity environment, resulting in an increase in indication error. To solve this problem, adjust the instrument according to the standard gas instructions provided by the oxygen analyzer manufacturer. If the display value cannot reach the standard gas concentration, it can be judged that the sensor has failed and needs to be replaced with a new one.

  2. If the response is slow or there is no response after the gas is introduced, first check whether the ventilation holes of the sensor components in the medical oxygen analyzer are blocked. If the inlet channel is blocked or the surroundings are filled with debris, it will cause the inlet channel to be blocked, making the hydrogen sulfide gas detector slow to react and the sensitivity to decrease. Then, clear the blockage or clean up the debris around the inlet channel. If there is no blockage, the cause of the fault may be the aging or failure of the internal sensor in the detector, and the sensor needs to be replaced.

To ensure the accuracy of equipment measurements, the user needs to regularly send the sensor for calibration to ensure that the on-site analyzer can accurately obtain the oxygen concentration in the environment.

How to maintain medical oxygen analyzers?

The oxygen analyzer is a precision mechanical device. To measure accurately, it needs to be cleaned. The cleaning process is crucial. It needs to be protected from pollution by acidic compounds, organosilicon compounds, alkaline compounds, and other pollutants in daily use. Therefore, when we find dust or contaminated items in the detection environment, we need to take preventive measures.

In addition, the operator needs to have a certain amount of knowledge, such as the correspondence between the medical oxygen analyzer and the alarm controller and their installation locations. At the same time, the on-site personnel need to regularly check whether the controller has been powered on for a long time to ensure that it can play a real role. If the alarm controller encounters water or moisture, it will affect its performance. Therefore, waterproof work needs to be done well to avoid equipment damage. The staff can regularly check whether the waterproof facilities are intact, and replace or repair them in time if problems are found.

The sensitivity of the oxygen analyzer will decrease after long-term use. Therefore, it is necessary to determine whether the equipment is within its service life and avoid direct contact with high-concentration flammable gases. This is because the combustion of flammable gases will produce a lot of reaction heat, which will reduce the sensitivity of the medical oxygen analyzer, and the reaction heat will damage the detector's bridge. During the combustion process, the deposited carbon black on the surface of the detector will cause the alarm to fail.

Daily maintenance of the oxygen analyzer can extend its service life and allow it to function normally and steadily. To ensure accuracy, it is necessary to do a good job of control.
