Digital Concrete Test Hammer Portable Concrete Hammer Tester

My engineer says this is the best yet!

I purchased to complete roll hardness test for non woven material. It does a great job, and it is easy to use after reviewing the manual. It’s a lot cheaper than parotester. The only complaint is that our places a large dent in your roll because it is designed for concrete.

The first time I used it it worked fine, but then when I take measurements with the hammer, everything appears fine on the screen but it does not save the data in memory. every time I have to do concrete tests, I have to take the measurements manually and do the statistical calculations myself
