What is the typical recommendation for moving the probe of an electronic leak detector?

Moving the probe of an electronic leak detector at approximately 1 inch per second is typically recommended for several reasons. This slower speed allows for more accurate detection of gas leaks, as it gives the sensor time to respond to the presence of any leak and increases the likelihood that the detector will register any small amounts of gas that may be escaping.

When the probe is moved too quickly, there is a risk of missing leaks because the detector may not have sufficient time to sense low concentrations of gas. Moreover, maintaining a consistent speed is crucial in ensuring that data collected is uniform and reliable, and 1 inch per second strikes a balance between thorough inspection and operational efficiency.

While other speeds may be considered when using different instruments or in specific situations, the recommendation for 1 inch per second reflects a standard approach to ensure thorough and effective leak detection.
