Ultrasonic Thickness Gauge R7900 REED

Máy đo chiều dày bằng siêu âm REED R7900

For the accurate, non-destructive measurement of the thickness of a wide range of materials including metals, plastic, ceramics, composites, epoxies, glass, and other ultrasonic conductive materials.

Rebound hardness testing is particularly useful for large, coarse grained materials, forged parts and all types of cast materials because the spherical tip of the impact device processes the characteristics of the casting structure better
Measures the velocity of a propelled impact body directly before and after the impact onto the test material's surface; the impact creates a plastic deformation of the surface, i.e. an indentation, due to which the impact body loses part of its original speed - or energy. The ratio between both velocities indicates the hardness of the material (it will lose more velocity when creating a bigger indentation on softer material)
Capable of automatically converting and displaying measurements into Rockwell (HRC, HRB, HRA), Brinell (HB), Leeb (HL), Vickers (HV) and Shore (HS) hardness values
Materials that can typically be tested include cast steel, alloy tool steel, stainless steel, aluminum, bronze, copper, cast irons, etc.
Conversion of measurements to tensile strength (U.T.S.)
Large capacity memory can store up to 350 groups of information (depending upon impact times) including measurement value, mean value, testing date, impact direction, impact times, material and hardness scale
Real-time clock
Mini USB data interface
Operates on a rechargeable lithium battery
