Product details
|
explain:
This instrument is a HT-225 rebound tester that complies with JGJ/T23-2001 technical specifications and is used to detect concrete resistance within the range of 10-60Mpa
The pressure degree, system standard energy is 2.207J, and the indication system is a medium-sized rebound gauge with pointer direct reading, which is regulated by the national metrological verification regulations
Cheng's "Concrete Rebound Tester" (JJG817-93) and industry standard "Technical Specification for Testing Concrete Compressive Strength by Rebound Method"
Editor in Chief - Supervised by Shaanxi Provincial Institute of Architectural Science Research and Design.
characteristic:
Lightweight (2/3 less labor-saving than similar products), flexible, affordable, no need for power supply, easy to control, and the button adopts stretching technology that is not easy to remove
The falling and pointer are easy to adjust friction, making them the preferred non-destructive testing instrument for on-site use.
Main technical parameters:
Pointer length: 20.0 ± 0.2 (mm)
Pointer friction force: 0.65 ± 0.15 (N)
Spherical radius at the end of the firing rod: 25 ± 1.0 (mm)
Elastic impact tension spring stiffness: 785.0 ± 40.0 (N/m)
Release position of the hammer: at the "100" mark on the scale line
Working length of rebound spring: 61.5.0 ± 0.3 (mm)
Impact length of the hammer: 75 ± 0.3
Jump position of the hammer: at the "0" mark on the scale
Steel anvil set value: 80 ± 2 (our factory's factory products are controlled between 80-81)
