1. It adopts the latest digital signal processing chip and digital filter chip from abroad, and the controller integrates 16M cache, which makes the reaction more sensitive.
2, using 7-inch high-definition digital touch color LCD screen, resolution of 800 * 480, full touch design, easy to operate.
3, 9 probes use the wireless module to send signals, no wiring required. And 9 probes can be measured at the same time, which greatly increases the measurement range, saving users time to find leaks.
4. The user can adjust the frequency range arbitrarily within the range of 70HZ-9000HZ.
5. In the range of 70HZ-9000HZ, the distribution of noise signals at each frequency can be displayed in real time.
6, the sensor built-in preamplifier circuit, the use of rubber ring sealing and buffering, as well as the application of professional acoustic methods, making the ability to capture noise higher than similar products.
7, using a large capacity battery, can work continuously for more than ten hours.
8, super anti-interference circuit design, the digital signal and analog signal are effectively isolated, eliminating the noise generated by the digital circuit.
