What should be paid attention to when using Pilani vacuum timers?

Pilani vacuum gauge is a kind of vacuum measuring instrument widely used in laboratory and industrial manufacturing. The following precautions should be observed when using Pilani vacuum timers:

1. Select the correct range of measured pressure

There are different measurement ranges, such as 10 ^ -4 to 10 ^ 3 millibars. Before use, it is necessary to confirm whether the measurement range matches the pressure range of the measured object, otherwise the measurement cannot be carried out correctly.

2. Calibration

Ensure that it is calibrated before each use to ensure accuracy and reliability. The calibration process involves connecting it to a known pressure source and adjusting the reading to match the pressure of that source.

3. Install the correct connectors and seals

Proper installation and tightening of joints and seals is crucial to ensure their proper operation and prevent leakage. If the connector or seal is damaged or loose, it must be replaced or reinstalled to avoid affecting the measurement results.

4. Avoiding pollution

It has high sensitivity and is easily affected by pollutants. Before measuring, the surface of the measured object, as well as the internal chambers and sensors, should be cleaned.

5. Avoid excessive pressure or temperature

Avoid applying too high pressure or temperature to the vacuum gauge, as this may cause damage or affect its accuracy. It is necessary to select the appropriate model based on the pressure and temperature range, and strictly follow the user manual for operation.

6. Pay attention to safety

Always pay attention to safety when using timing. For example, during the measurement process, do not touch the electrodes and do not expose them to strong electric or magnetic fields.

7. Maintenance and upkeep

Regular maintenance and upkeep can extend its service life and improve its reliability. For example, special cleaning liquids can be used to clean sensors. In addition, components and consumables should be replaced according to the user manual to ensure accuracy and reliability.

In short, the correct and safe use of the Pilani vacuum gauge requires some practice and experience, but as long as you follow the instructions and the above precautions to operate, you can obtain accurate and reliable measurement results and protect the integrity of the equipment.
