Product Description
1.Overview
MITECH MT-1A digital portable magnetic flaw detector, adopts large capacity lithium battery power
supply. DC is exchanged into AC by the inverter and the phase shifted signal processor to provide power
for the detector, it solves the shortcomings of traditional magnetic particle detector relying on the 220V
power supply. It has low power consumption and can continuous work for more than 4 hours. The battery
can be charged while working or off. It can real-time monitoring, process image, save data, print the test
report, track inspection results, meet the requirements of standard operation and management.
Especially suitable for the field without power supply field testing and high-altitude operations, it realizes
the innovation of magnetic powder digital inspection.

It is widely used in the industry of aircraft manufacturing, boiler and pressure vessel, electric, oil field,
shipbuilding, turbine and combustion engine parts, mine, machinery, standard parts, oil pump, vehicle
parts, bridging, chemical, railway, large mechanical components, steel structure equipment etc. It mainly
detects the surface detection of forging, quenching, welding, fatigue, for example, irregular workpiece of
chain, crankshaft, bearing, high strength bolt, spring, forging, petrochemical pipe, valve, vane, gear,
anchor chain, welding seam etc.
1.2 Features
The large capacity lithium battery makes it portable, solves the drawbacks of traditional, magnetic
particle detector relying on the 220V power supply, with low power consumption, small size, battery
can be charged when the detector is on and off. It is especially suitable for testing in field or high
altitude;
The brightness, power, lighting form of Mitech portable magnetic flaw detector series are adjustable,
to meet the needs of different testing environment.
New power mode improves the sensitivity and accuracy of surface and depth detection.
Electromagnetic yoke adopts pulse power supply technology can continuous work without rest.
Combines the advantages of traditional electromagnetic yoke, can make fast, clear, correct test of
the surface.
The brightness, power, polar distance are adjustable to meet the needs of different measurement
conditions;
The product is equipped with portable package, operator can put it on the waist, greatly reduce the
labor intensity, improve work efficiency.

display the location, shape, size and degree of the flaws. It has the functions of software
management, image processing and recognition, quantitative and nature analysis of the flaw, and
PC communication, detection process can be monitored, the results can be traced and meet the
requirements of standard operation and management
Stationary and portable two types detector, dry and wet technique are available to meet the different
needs of different customers
High capacity lithium battery makes it portable, solves the drawbacks of traditional, magnetic
particle detector relying on 220V. Low power consumption, small volume, alternative charge method,
especially suitable for field and high altitude inspection.
New power supply mode improves the sensitivity and accuracy of surface and depth detection
Build-in industrial high-definition micro camera, real-time record test results, effectively monitor the
flaws that we can't see, built in ROM can communicate with computer, the defects and photos can
be transferred to PC, output the inspection report in Excel format.
The USB port can transfer the data waveform to the U disk to save, print inspection report, realize
network management.
Adopts electromagnetic yoke power supply technology can realize continuous work, without time
limit.
Different electromagnetic yokes can meet different requirements. With auto check, indication test
functions
The detector is compact, lightweight, easy to carry, can greatly reduce the work intensity of the
testing personnel.
1.6 Working Principle
Put the workpiece into high-intensity magnetic field, connect electric to make it magnetized, if there are
flaws (crack,slag) in or near the surface, there will be a leakage around the flaws. Put good quality
magnetic powder(usually the magnetic iron oxide powder)on the object, magnetic powder will gather
together near the leaked magnetic field, piled up to form visible traces of magnetic powder. In the proper
light, we can see the marks and judge the position, size, shape and degree of the flaws.
