Product Description: 
Mashproject is a  well-known Russian military background ultrasonic hardness tester manufacturing  enterprise,Tkm-459 is a  portable ultrasonic hardness tester, which is small in size and exquisite in  workmanship. It has been widely used in Russian military industry and global  manufacturers for decades,and we successfully introduced the product to the  Chinese market, with the value of cost-effective quickly get the user's favor.  The ultrasonic hardness tester is affected by the thickness and quality of the  product very little, and solves the problem of measuring the product of thin  wall and complex shape. It has the characteristics of quick field measurement  and multiple probes, which can be simple and direct display test results.
