Brand : Mitech
Model : MFD-350B
Product Description
MFD350B digital ultrasonic flaw detector with 320*240 TFT LCD, it can test, orient, evaluate and diagnose various flaws such as crack, lard, air hole in workpiece’s interior swiftly and accurately without any destruction. It can be used in Laboratory as well as in engineering filed. With range of 0-6000mm, it can meet the requirement for general defect inspection in manufacturing industry, metallurgical industry, metal processing industry, chemical industry and so on. Low power design with large capacity and high performance lithium battery module, it can be long standby for months. High quality with low price, it is the first choice for the practical economic model for ultrasonic testing equipment.
The instrument can be widely used in locating and sizing hidden cracks, voids, disbands and similar discontinuities in welds, forgings, billets, axles, shafts, tanks, pressure vessels, turbines and structural components.
Product Features
Gate Alarm
Gate position, gate width and gate height can be adjustable at will. The B gate can chose to set wave-getting alarm or wave-losing alarm. The beep in gate and LED light can be alarmed or closed (the LED light alarm is very effective under the noise environment).
Data Storage
The instrument is built with mass storage, the data and files will not be lost because of instrument power breakdown. The storage contents included channel parameters, waveform pictures and video files. It supports 100 groups of flaw detecting parameters channels. It can preset well for the combination parameters of various types of probes and instruments as well as set testing standards for each industry freely. It can save 1000 pictures of detecting echo signals and parameters. It can realize to save, read and transfer the data via the USB port.
Video Function
The instrument supports for saving the inspection process as video file and save it to the internal storage card. Video file can be replayed through the instrument. The instrument can support 2 minutes video.
REAL-TIME CLOCK
Record and save the tracking record of detecting date and time in real time.
Communication
With USB2.0 high speed communication interface, it also can use special software to upload and download data through the USB port.
Battery Module
The large capacity lithium battery module is easy to be assembled and disassembled. It can be charged independently but also charged by inserting wire. Its continuously working time is more than 8 hours.
