HT-225W Digital Concrete Rebound TesterDetailed product description：

HT-225W digital concrete rebound tester

Rebound value (Rm), average carbonization depth value (dm), and concrete strength value in the test area (∫ ccu).
On site testing can obtain the concrete strength ∫ ccu in the testing area.
Printing record data can be used as engineering quality vouchers for storage and backup.
The storage period is about 2 years (suitable for storage under low temperature and non strong light conditions). It can be tested in 1-10 test areas at a time and can be tested continuously.
Easy to operate: F1 SW switch key
F2 SW setting keys (Dt, dm, α, # area code)
