Description Overview GAOTek Auto Calibrated Testing Flaw Detector series is specially designed for engineering personnel use on non-destructive testing. And its main usage scopes are testing, position, evaluation and diagnosis of various destruction. It can easily and accurately conduct non-destructive testing on welding defects, cracks, internal pores of the work piece and other defects. It is widely used on industries such as electrical power project, boiler and pressure vessels, steel industry, aviation, railway transportation, automatic machine equipment and so on. it is an indispensable testing tool in the field of non-destructive testing. Features Timely and dynamic colourful video Various industrial reports can be chosen Sound-light alarm Low battery alarming under various condition Single crystal /double /transmission probe can be chosen TFT Colour screen with 5.7 inches Brightness and colour can be set freely With the functions of defect, wave crest, memory, assist qualitative evaluation Positive half-wave, negative half-wave, full wave Three kinds of detection mode Lithium battery ensures more than 20h continuous working Can do testing while charging 0 data transmission Automatic calibration Technical Specifications Testing scope (mm) 0 mm to 25000 Working freq.
