Be careful using this as it only gives the strength near the surface. It is also very susceptible to user errors (not holding correctly, etc.)
The big advantage is that it gives strength readings in seconds. Take lots and use the average.
They can be found on the net. Use your favorite search engine.

The Windsor Probe would be a bit better than the Schmidt hammer, but the definitive assessment should be done by coring as you need to know the integrity of the concrete as well as its strength.
