Measure concrete strength using air pressure!
The air pressure pin penetration testing machine is a device that drives a specialized pin into concrete using air pressure and measures the penetration depth to estimate the concrete strength. It is a simple testing method that replaces the pull-out testing machine used for initial strength testing of sprayed concrete, does not require test specimens, and allows for testing the concrete sprayed onto wall surfaces in situ. 【Features】 ○ Measures concrete strength using air pressure ○ Japan Highway Public Corporation Standard JHS726-2001 For more details, please contact us or download the catalog.
