CONCRETE TEST HAMMER Type NR ( CO-550) , ASTM C-805
Code Series : CO-550.3S
Type NR, displays rebound values recorded on a strip chart. The most frequently used device & method for non-destructive strength testing of concrete & structural components.
Concrete testing with the Original Schmidt test hammer is the most frequent used method for non-destructive concrete testing worldwide.
For every demand and specific test application, Proceq offers the right concrete test hammer.
Original Schmidt concrete test hammers are available in models with different impact energies in order to meet the needs to test a wide range of material types and sizes.
Types NR are best-suited and specially developed for assessing the quality and compressive strength characteristics of concrete with the range of 10 to 70 N/ mm2 ( 1’ 450 to 10’ 152 psi) .
Versions incorporating paper chart recorders ( LR and NR) can automatically register the rebound values on a paper strip chart.
Type NR: Rebound values are recorded as a bar chart on a paper strip which has a capacity for 4’ 000 test impacts
Applications :
- Used for the non-destructive measurement of the concrete/ mortar compressive strength characteristics
- Control of uniform concrete quality ( in-situ concrete and prefabricated structures)
- Detection of weak spots in the concrete
