Vernier caliper

 

A measuring instrument that can measure length (shape), inner diameter, or step difference.
and it can measure with relatively high precision.
 

     Micrometer
 

The measurement accuracy of the centigrade is higher than that of the vernier caliper, also called micrometer. The commonly used spiral readings have the centigrade and the micrometer.
The reading value of the centigrade is 0.01mm, and the reading value of the micrometer is 0.001mm.

                               Rockwell hardness tester

 

Perform hardness testing of finished and semifinished products to ensure stable product quality

 
                                      Electronic Conduction Detector
 

The electrical conductivity (ec value) can be tested for different properties and treatment states to ensure the quality and uniformity of heat treatment.
Non-destructive detection of electrical conductivity to verify the integrity after heat treatment.
