Product Description

Introduction of PQWT-CL800 Pipe Leak Detector
PQWT-CL800 pipe leak detector is a leak detection instrument with excellent performance. It has super anti-interference and data processing capabilities, which can make your work easier. It has the following main characteristics:
1. The latest digital signal processing chips and digital filter chips from abroad are adopted. The controller integrates 16M buffer, and the response is more sensitive. Especially, it can filter the interference of environmental noise, discriminate the leakage noise, and make the operator lock the leakage point faster. A kind of
2. Using inch high-definition digital touch color LCD screen with resolution of 800*480, it can provide 8 display pages, which can display measurement parameters more clearly and intuitively, and the design of full touch screen is simple to operate. A kind of
3. It has a frequency range of 50-5000Hz (spectrum analysis). It can display the distribution of noise signal on each frequency in real time.
PQWT-CL800 is a mid to high end model, suitable for leak detection in medium-sized pipeline systems due to its reasonable price and high performance.
main features
Moderate sensitivity: Suitable for leak detection of different pipeline materials and structures.
Data recording function: Real time recording of detection data for subsequent analysis.
Lightweight design: easy to carry, suitable for outdoor work.
application
Leakage monitoring of water supply pipelines in small and medium-sized cities.
Daily inspection of industrial facilities.
Groundwater detection work with complex conditions.
