Product Details
VTL-20D series of leaks are channel-type fixed-value standard leaks, and the leak element is a micro-channel capillary, with a leak rate or calibration accuracy of 0.1g/a, which supports customers to specify leak rate or annual leak rate customization, such as 1g/a,2.5g/a,5g/a,..., Other leakage rate units can also be specified, such as pa m/s (≥ 5x 10-6Pa m3/s), and large leakage rate of 10~100g/a can also be customized. This product combines the advantages of fixed leak at home and abroad to develop 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 refrigeration and other industries at home and abroad.
Product Advantages
The product has a stable leakage rate, adjustable leakage rate, repeatable filling
Low cost, easy to carry, etc.
