Product Introduction
Water leak detector ( English Version)
Our china coal having more than 20 years' development experience of water leak detector,combined the advantage of same type instrument,and add more practical new function,adopt digital signals processing techniques and new material,develop the digital water leak detector using in underground pressure pipes.
1) This detector adopt advanced digital signals processing techniques and digital filter circuit,improve anti-jamming performance,to detect precisely.Large LCD screens could accurately display the measure parameter,distinguish the environmental noise and leak water noise signals automatically, let the operator judge the water leak doubt intuitively.
2) The spectral analysis,it could display the noise signals' s relative distributions in various frequency.
3) It could record (time- signal noise) curve automatically,continually monitor the noise signals,provide reliable analysis evidence.
4) It could preserve many record data,it could record live sound.
5) It adopt high quality sensor's material and circuit,improve the sound intelligibility.
6) The vibration sensor inner has signal amplification electric circuit,lower the noise interference.
