## Description

Operation video on official website: www.pqwtcs.com/NewsDetail.aspxnid3579&classid246 PQWTCL200,300,400,500,600 series pipeline leak detector is a high-performance leak detector, has strong anti-jamming and data processing capabilities, you can make your work easier. It has the following key features. 1. Using the latest digital signal processing chip and digital filter chip, built-in 16m Cache controller, more responsive. In particular, it can filter with environmental noise interference, and check leakage noise, allowing the operator to quickly seal the leakage points. 2. 7 inch HD color digital LCD touch screen with 800*480 resolution, provides 12 display pages, can show the measurement parameters more clearly and intuitively, full touch screen design, simple operation. 3. Each has 1~5000Hz, 1~6000Hz, 1~7000Hz, 1~8000Hz, 1~900Hz, 50~5000Hz frequency range (spectrum analysis), the noise signal distribution of each frequency can be displayed in real time. 4. Automatic drawing of continuous noise curve (location mode) within a certain time, so that the position of the leakage point is determined more quickly. 5. The sensor is a built-in amplifier circuit, using rubber ring and pad and applying professional audio methods, which makes the noise capture ability higher than similar products. 6. Adopt the latest noise detection element, clear sounds. 7. The number and time of recordings is unlimited, which is not lost after shutdown, and can be analyzed at any time. 8. Using a large-capacity battery, it can work for more than ten hours, and can be removed for charging and charging online. 9. Superior anti-jamming circuit design, digital signal and analog signal effectively isolate and eliminate noise generated by digital circuit.
