Dec 20, 2017

Our famous domestic customer bought our rockwell and superficial double rockwell hardness tester in October, 2013.

Our after-sales service team have maintained instrument to customer side.

During past 4 year, rockwell and superficial double rockwell hardness tester worked stable and accuracy which is got good reputation from customer.

For detail information of this model, please check following:




Multi-function digital twin Rockwell hardness tester has high level automation, stable and reliable performance, it can meet the Rockwell hardness test requirements of all metal materials. it is equipped with sophisticated sensors so that can test data more accurate ; 5.6 inch digital LCD screen provide comprehensive data for quality control. It is easy to preserve the data for a long time.
