UTF0022 Ultrasonic Flaw Detector

Functions
1. Wave peak memory: real time envelopes show the highest wave of the flaws and record the maximum value of the flaws, it is helpful to locate the flaws precisely and scan the work piece quickly. With the help of envelope waveform, the quality of the flaws can be determined. 
2. Automatic gain: automatically adjust the gain to the preset amplitude height.
3. Alarming function: afferent echo/echo loss alarming.
4. Real-time clock: automatically record and store the date and time of waveforms.
5. Display freezing: catch waveforms and sound path data at any moment, and the gate can be moved after freezing to measure the echo parameters.
6. Flaw positioning: real-time display sound path S, horizontal X, depth Y, and wave height H.
7. Digital Reject: 0-80%, increase by 1%, unaffecting the linearity and gain.
8. Wave height reading: three display modes, namely relative wave height, dB difference relative to the gate, and dB difference relative to DAC curve.
9. Data communication: communicate with the computer through RS232 port to transmit waveforms and data so as to manage the result of detection on the computer, and generate the flaw detection reports, as well as print out reports.
10. 2 independent measurement gates, monitoring the echo amplitude and the sound path distance.
11. When using transverse wave to detect flaws, the depths of the second and third waves are automatically calculated according to the slab thickness.
12. Perfect DAC/AVG curve functions, the curves change along with the changes of the gain, sound path, and displacement. It can be straight line or curve.
13. True color TFT LCD whose brightness is adjustable, with many color schemes to choose freely.
14. DAC Curvilinear Distance Compensation: the device is designed for distance compensation. When the resolving power in the near field is not influenced, only the remote signal will be compensated for its sensitivity so as to improve the testing range of the device significantly.
15. Φ Value calculation: the device can calculate the equivalent of the flaw according to the flaw wave height automatically.

Features

1. The firm and durable UTF0022 are specially designed for the hostile site environment. The pan-seal design which is particular in the nation enables it to defend against dampness, sandstorm, dust, or pollution caused by all sorts of harsh environments from sea to desert. 
2. Pan-seal design, including tool housing, battery case, fastening screws, and external interface.
3. 31 copper screw nuts are inlaid in the hard plastic casing.
4. The hand strap can be installed for both hands so that you can hold the machine with your left or right hand.
5. The innovative rotating positioning stand is convenient.
6. The probe interface is optional for BNC or Lemo.
7. The D-shaped ring on the instrument is convenient for you to install a chest strap.
8. The nice surface of the casing is antiskid with eroded textures.
9. Two battery schemes which are particular in the nation, when there is no AC supply, if the battery pact exhausts, you can use 6 ordinary LR14 batteries:
Innovative high power lithium batteries of notebook style

10. Full screen function, the echo display area can cover the entire screen, which provides you with the sense of the maximum window.
11. Solid waveform display, the visual contrast of waveforms is increased so the undetection is hard to happen when fast scan is carried out.
12. Bulk storage, up to 1000 data sets can be stored, including waveforms, curves, and parameters (containing the traditional 1000 channels).
13. Echo-echo thickness measurement, zero calibration is avoided, and the net thickness of the base material can be directly measured through the coating.
14. Two operation interfaces are available: Chinese and English.
15. Easy to use, the user can master the operation method very fast.
16. The squared ultrasonic pulse generator with changeable width and scope is initiative domestically. It replaces the traditional method of matching probe by changing damping with adjusting the pulse energy and pulse width. Thus, the probe can be exactly fit for the testing and the resolution and penetrating power of the approaching surface can be enhanced significantly. It is specially fit for the testing of large scale of forge piece, casting piece and non-metal with the requirement of higher penetrating power and lower electric noise.
● The voltage of the pulse generator can be changed between 50V to 400V continuously, so that no matter thin plate or hard-penetrated work-piece can be matched with the most fitful probe.
● The width of the pulse can be change d between 25ns to 1000ns continuously, so that the best sensitivity can be realized with the help of different probes with different frequency. 
17. Damping can be changed among 4 levels: 33/50/100/500Ω, so that the best performance of the probe can be attained and the different requirements of the sensitivity and resolution can be realized.
18. The wave signal filter can be changed between 2 levels: 1-4MHz/0.5-15MHz. Each individual advantage of narrowband and broadband filter can be achieved.
19. The repeating frequency can be changed freely to avoid unreal signal.
