Ultrasonic Flaw Detector NOVOTEST UD2301

An ultrasonic flaw detector is designed to search for voids and inhomogeneities inside the materials under testing with ultrasound. It is the most common device in the world for non-destructive testing of metal (and other materials with low attenuation of ultrasonic waves) products in production, as well as objects in operation.

Ultrasonic Flaw Detector NOVOTEST UD2301 is a powerful, ergonomic, portable device that has all the functions of a general industrial ultrasonic flaw detectors and can be used in laboratories and workshops, and is perfect for field use.



The main advantages of the Ultrasonic Flaw Detector NOVOTEST UD2301 are below:


The device has wide functionality:

– presentation of the signal like A-scan and B-scan, which allows the operator to select the desired operating mode in accordance with the task;

– the device has two independent gates, with the ability to evaluate parameters in different areas on the scan, also using the automatic defect alarm function the limits can be configured individually for each gate.

– for better signal processing, the device has functions of freezing and envelope, which allows the user to more accurately evaluate the received data.

The device implements the Distance Amplitude Correction (DAC) and Time Varied Gain (TVG) functions, with the setting up to 16 points, which allows the operator to evaluate the equivalent reflector size at various depths.


Also in the device there are Distance Gain Size (equivalent) diagrams that allow user to build an amplitude curve from one standard reflector, as well as calculate the equivalent reflector size of tested discontinuities.

The device has an archive for storing measurements, settings for a specific object, settings of transducers to quickly switch settings when changing the testing object .


A unique screen orientation function is implemented in the Ultrasonic Flaw Detector NOVOTEST UD2301, depending on the conditions under which the testing is performed, the screen orientation can be either vertical or horizontal. Also, the screen can be configured for both right-handed and left-handed people, i.e. the screen can be rotated 360°.

The device powered from three standard AA batteries, which makes the device completely independent of the stationary power source, the internal charger allows the battery to be charged from the standard USB 5V socket, with power bank the device can be used continuously for almost unlimited time.


The device has a transflective TFT display with a resolution of 480x320px, the enclosure is made in an ergonomic shape with a rubber bumper, which makes the device shockproof and resistant to falls. To connect the probes, standard connectors are used, which allows the operator to use any transducers without restrictions.

The device is supplied with PC software for uploading the measurement archive and processing the results.
