Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • In the actual procurement process of leak detection machines, it is recommended to prioritize checking key parameters such as detection accuracy, pressure range, and applicable medium types to ensure compatibility with the production line process requirements.
  • For different application scenarios (such as pipeline sealing detection or packaging container leakage screening), it is necessary to clarify the automation level and compatibility differences of leak detection machines to avoid functional redundancy or insufficiency.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • For high-frequency continuous operation environments, it is recommended to pay attention to the stability and average time between failures of leak detectors to reduce the impact of maintenance costs on production efficiency.
