Purchasing Guide

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

  • For procurement requirements that require the use of leak meters, it is recommended to prioritize confirming key technical parameters such as detection accuracy and range, such as whether they meet the measurement requirements for small leaks or high-pressure environments.
  • When applying leak detectors in the chemical or energy industry, explosion-proof or portable designs should be selected according to the scenario, while paying attention to sensor response speed and environmental adaptability.
  • 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.
  • During the procurement process of leak detectors, it is recommended to compare the stability and maintenance costs of different models. Long term operating equipment should focus on indicators such as durability and calibration cycles.

Knowledge Base

Q

Gas leak detector is an important safety monitoring device with broad application prospects and market demand. When choosing and using, users should pay attention to its working principle, product features, main applications, and selection suggestions to ensure that it can play its maximum role. Gas leak detector is an important safety monitoring device with broad application prospects and market demand

Q

Baidu AiGou has found pictures related to different categories of leak inspection devices for you, taking you to appreciate the diversity and uniqueness of leak inspection devices. At the same time, we also recommend high-quality leak detection equipment products for you, allowing you to easily and quickly find the most suitable leak detection equipment for yourself when purchasing.

Q

The core principle revolves around the correlation between sealing performance and pressure/flow changes, and common detection methods include: pressure Attenuation method (filling a specific pressure of gas or liquid into the interior of the test object, continuously monitoring pressure changes, and if the pressure drop rate exceeds the set threshold, it is determined that there is a leak), vacuum method (vacuuming the exterior of the test object and monitoring the internal pressure rise)
