What are the maintenance measures for air permeability tester?

The maintenance measures of the air permeability meter include daily equipment cleaning, equipment calibration, inspection of air paths and pipes, regular replacement of filters, lubrication of moving parts, inspection of electrical connections and sensors, recording of equipment usage, and timely handling of abnormal situations.

The air permeability meter is a professional instrument used to measure the air permeability of materials. In order to ensure the accuracy of the measurement and the long-term stable operation of the equipment, regular maintenance is required. In this article, the editor of Hut Instrument will introduce the maintenance measures of the air permeability meter to help users better understand and use the equipment.

Maintenance measures of the air permeability meter
1. Daily maintenance measures
(1) Keep the equipment clean: Since dust, fiber or sample residue may enter the instrument during the measurement process, it is very important to regularly clean the measurement channel and the workbench surface to prevent contamination from affecting the measurement results.
(2) Calibrate the equipment: To ensure the measurement accuracy of the air permeability meter, the equipment should be calibrated regularly. According to the calibration guide provided by the equipment manufacturer, standard samples should be used for calibration, and the equipment parameters should be adjusted to ensure the accuracy of the measurement data.
(3) Check the air path and pipeline: Check whether there is air leakage in the air path, ensure that the connection is tight, without cracks or wear. If necessary, replace the aged pipeline and seal ring to prevent unstable airflow from causing measurement errors.

2. Regular maintenance measures
(1) Regularly replace the filter: The filter should be checked and replaced regularly according to the frequency of use and environmental conditions. It is generally recommended to replace the filter every 6 months to 1 year to ensure the cleanliness and stability of the airflow.
(2) Lubricate moving parts: Some parts inside the air permeability meter need to be lubricated regularly to ensure their smooth operation. Especially when it comes to sample clamping devices or air pump moving parts, lubrication can reduce friction and prevent mechanical wear.
(3) Check the electrical connection and sensor: The electrical part and sensor of the air permeability meter are its core components. Regularly check whether the electrical connection is firm, loose or in poor contact. Also pay attention to the working status of the sensor to ensure that its readings are accurate and responsive.
3. Troubleshooting and treatment measures
(1) Record equipment usage: It is recommended to establish equipment usage records when using the air permeability meter, which helps to track the equipment usage and facilitate troubleshooting when problems occur.
(2) Timely handle abnormal situations: During use, if the air permeability meter makes abnormal sounds, the measurement results fluctuate greatly, or the operation fails, it should be stopped immediately for inspection and repair.
(3) Regular professional inspection: In addition to daily maintenance and self-inspection, it is recommended to conduct professional inspections once a year, and the equipment manufacturer or authorized maintenance center should conduct a comprehensive inspection and maintenance of the air permeability meter. The maintenance measures of the air permeability meter are the key to ensuring its long-term stable operation and measurement accuracy. Through daily cleaning, regular calibration, inspection of key components and other measures, the service life of the equipment can be extended, the maintenance cost can be reduced, and more accurate air permeability performance measurement data can be provided.
