FAQ
1. Q: Are you a direct manufacturer ?
A: Yes, we are manufacture in Beijing, China, we produce hardness tester, also the surface roughness tester, ultrasonic thickness gauge, coating thickness gauge etc.
2. Q: Can it test light work piece
A: Take D probe as example
If  the weight is 2-5kg, use a suitable support ring attached to the probe to ensure test firmly.
If  the weight is 0.05-2kg, use thick Grease coupling it to the heavy work piece
