Helium leak detector is a universal leak detector composed of helium gas and mass flow controller. It can be used to detect the sealing performance of various types of seals and detect minimal leaks.
The helium leak detector uses the flow characteristics of helium gas for sealing testing. When helium gas passes through the sealing element, there will be a certain amount of leakage, and the instrument can detect these leaks, thereby determining the sealing performance of the sealing element.
1. The working principle of a helium leak detector is to use the electrochemical effect to decompose water molecules in helium into hydrogen and oxygen, and then detect the concentration changes of hydrogen to calculate the gas leakage amount.
2. During operation, the helium leak detector will charge helium gas into the measurement site, and then electrochemically decompose the water molecules in the helium gas into hydrogen and oxygen through an electrode. The hydrogen concentration at the measurement site will change with the amount of gas leakage.
3. When the hydrogen concentration exceeds a certain limit, the helium leak detector will sound an alarm to alert the operator. In this way, gas leaks can be detected in a timely manner, measures can be taken in a timely manner to prevent gas leaks from causing harm to the environment and human health.
4. In addition, helium leak detectors can also calculate gas leakage by recording changes in hydrogen concentration, providing accurate detection data for operators.

When the hydrogen concentration exceeds a certain limit, the helium leak detector will sound an alarm to remind operators to conduct timely detection to protect environmental safety and prevent gas leakage from causing harm to the environment and human health.
1. Fast and accurate: Helium leak detectors can quickly and accurately detect the sealing of sealing components, and the detection efficiency is also higher than other methods.
2. Sensitive detection: The helium leak detector can detect very small vulnerabilities, which is also the reason why it can detect more types of seals.
3. Easy to operate: The helium leak detector is easy to operate, just connect the helium gas source to perform the detection, and the operation does not require too much technical knowledge.
1. Regular inspection: Regularly inspect the connection components of the helium leak detector to ensure its correct installation and avoid any loopholes.
2. Regular replacement: Regularly replace the testing components of the helium leak detector to ensure its normal use.
3. Maintenance: Regularly maintain the helium leak detector to ensure its normal operation.
