The underground water leak detector is mainly used to detect the leakage of buried tap water pipelines, and the listening instrument to locate the leakage point can also be used to locate the leakage point of other liquids and gases. With pointer, cursor, audio, digital display methods. Small size, light weight, easy to carry, while choosing a groundwater leak detector requires special attention.
The underground water leak detector should choose high resolution. Simply put, it is the exact number of digits detected, such as 1Pa or 0.1pa. There are many resolution units, such as Pa, ml / min, etc. Choose according to your product testing requirements. Accuracy testing of groundwater leak detectors is required. The first meaning of precision is accuracy. For example, shooting can directly hit the bullseye. The second meaning is the allowable deviation range. The size of the bull's eye area is the same as hitting the bull's eye, and the accuracy of hitting a small area of the bull's eye is high.
Underground water leak detector require multiple repetitive tests. This is the most important index, which can reflect the comprehensive performance of the instrument. The so-called repeatability refers to the consistency of the data displayed by the instrument under the same ambient temperature and the same test pressure. The choice of groundwater leak detector depends on the strength of the manufacturer, and the overall strength of the business can be comprehensively judged from the aspects of the quality of sales staff, market share, and customer strength.
