HT-225 concrete rebound tester

This instrument is a HT-225 rebound tester that complies with JGJ/T23-2001 technical specifications and is used to test the compressive strength of concrete within the range of 10-60Mpa,

The standard energy of the system is 2.207J, and the indication system is a medium-sized rebound instrument with pointer direct reading, which is regulated by the national metrological verification regulation "Concrete Rebound Instrument"

(JJG817-93) and the chief editor of the industry standard "Technical Specification for Testing Concrete Compressive Strength by Rebound Method" - Shaanxi Provincial Building Science Research Institute

Supervised by the Accounting Institute.
