High stability multi-channel ultrasonic flaw detector HFD-1000 with 2 - 16 channels
HFD-1000 multi-channel ultrasonic flaw detector for metal profiles designed for automatic or semi-automatic testing special equipment, can provide users with 2-16 channels. It has a stable performance of the door and wave interference detection alarm circuit, a high detection sensitivity and resolution, can well meet the pipe, bar and a variety of metal materials testing requirements. Instrument has high reliability, high sensitivity and strong resistance to electrical interference, low failure rate, easy maintenance, fully meet the business requirements and enhance the detection of product quality. Instrument by the synchronization control unit, a number of detection channels unit and display unit as a dual trace oscilloscope with the composition of 20MHZ. Not only can high-quality waveform display complete the task, user needs and habits based on a variety of display range selection and display, and user-friendly for the echo signal amplitude and accurate measurement of the relevant time, which can more accurately for testing.
Main features of the instrument:
1. using the building block of the instrument structure, testing the number of channels can be arbitrarily extended
2. high stability of the gate and alarm circuitry, alarm signals recognition of the relevant circuit
3. has a wide repetition rate range of options
4. can be accurately and easily measure the echo occurs, the different channels of echo contrast graphics display
5. instrument with a rich interface resources, design a variety of output interface circuit, including sound and light alarm, relay contact output, analog output like, wave gated echo signal peak square wave output, TTL level, the computer interface, etc. . (User selectable when ordering)
6. the output alarm signal delay, the delay can be set according to the length of time required on-site.
