Product Details
The VTL-20B series standard leak hole is a channel type refrigerant (halogen) standard leak hole, and the leak hole element is a micro-channel capillary tube. Its leak rate or calibration accuracy is 0.1g/a, and the leak rate range is:(0~10)g/a. Customers are supported to specify the leak rate or customize the annual leak rate, such as 1g/a,2.5g/a,5g/a,..., Other leakage rate units can also be specified, such as Pa · m3/s (≥ 5 × 10-6 Pa · m3/s), and large leakage rate of 10~100g/a can also be customized.
Halogen/refrigerant standard leak hole mainly uses the leakage characteristics of halogen gas or refrigerant gas under specific conditions to evaluate the sealing performance of the system or component by measuring the leakage rate. Its advantages are high measurement accuracy, fast response and good stability, which can meet the needs of leak detection in various complex environments. In the refrigeration and air conditioning industry, halogen/refrigerant standard leak holes are widely used in the leakage detection of refrigeration systems, air conditioning equipment, heat exchangers and other components. By using the halogen/refrigerant standard leak hole, engineers can accurately find the leak rate, repair and replace it in time, so as to ensure the normal operation of the system and extend the service life of the equipment.
This product combines the advantages of domestic and foreign refrigerant (halogen) leak hole specially developed a set of standard instruments with independent intellectual property rights. The product is well adapted to the demand of strict control of product leak detection process in the refrigeration industry at home and abroad.

|
Advantages |
Stable leakage rate, adjustable leakage rate, repeatable filling, low cost, easy to carry, etc. |
||
|
Features |
The pressure gauge also indicates the leakage rate. If the leakage rate of the leakage hole is 3g/a, only the intake valve needs to be adjusted to make the pointer correspond to 3g/a, which is the actual leakage rate. The operation is simple and accurate, and conversion is not required. |

|
Precautions |
When charging, turn the intake pressure valve slowly, and pay attention to the change of the pointer of the leakage rate indicator. If it is overcharged, please release it immediately to prevent wasting calibration gas or damaging the indicator after overcharging. |
||
|
Application |
Can be used as an external standard leak hole, suitable for any halogen/Refrigerant leak detectorSF6 leak detector Volume calibration, such as INFICON (Infocom) |
