DJUS05非金屬超聲波儀的產(chǎn)地主要為北京，價(jià)格因廠家和配置不同而有所差異。例如，在1688平臺(tái)上，其價(jià)格在1.5萬(wàn)元左右。該儀器的生產(chǎn)廠家包括天津市盛克威科技有限公司、深圳市深博瑞儀器儀表有限公司等，這些廠家均具備專(zhuān)業(yè)的技術(shù)水平和良好的售后服務(wù)。

The DJUS05 Non-Metallic Ultrasonic Instrument is an advanced non-destructive testing device, widely used for the detection of non-metallic materials and components such as concrete and plastics. It employs the ultrasonic method, utilizing low-frequency ultrasonic instruments and transducers with a frequency of 20-250kHz to measure the acoustic parameters of non-metallic materials, such as sound velocity, amplitude, and dominant frequency. It then analyzes and determines the properties of the tested objects based on these parameters and their relative changes.

This instrument integrates multiple functions, including ultrasonic emission, dual-channel synchronous reception, high-speed digital signal acquisition, automatic detection of acoustic parameters, data analysis and processing, real-time result display, and data storage and output. It features high resolution and digitalization, with capabilities such as time-sharing sampling, superposition, filtering, signal enhancement, noise suppression, and on-site real-time calculation.

The main functions of the DJUS05 Non-Metallic Ultrasonic Instrument include the ultrasonic comprehensive method for detecting the compressive strength of concrete, detecting internal defects in concrete structures, detecting crack depth in concrete components, and detecting the integrity of concrete piles. It also offers extended functions such as full waveform logging in rock holes for engineering surveys. Its key features include a large TFT color touch screen without buttons, rapid and accurate time-of-flight and amplitude reading, support for various external triggering sources, and a maximum penetration thickness of more than 10 meters for defect-free concrete.

The instrument also boasts impressive technical specifications, with a time-of-flight reading accuracy of 0.1μs, a measurement range of 0.1—10240μs, and an amplitude reading range of 0—174dB. It features a 10.4-inch high-brightness color touch screen, 128Mb of memory, and a data storage capacity of up to 40Gb. Additionally, it supports USB data transfer and various printers.

The DJUS05 Non-Metallic Ultrasonic Instrument is mainly produced in Beijing, and its price varies depending on the manufacturer and configuration. For example, on the 1688 platform, the price is around 15,000 yuan. The manufacturers of this instrument include Tianjin Shengkewei Technology Co., Ltd, Shenzhen Sinbo Rui Instrument Co., Ltd, etc. These manufacturers all possess professional technical levels and good after-sales service.
