Proceq Original Schmidt Live

Proceq original schmidt Live is the latest generation Digital-Analog R-value hammer for non-destructive measurement of compressive strength of concrete. Original Schmidt Live provides a measurement range of 10 to 70 N/mm2 - Mean angle calculated, angle correction factor also applied automatically. Operates as a standalone analogue or as a digital hammer providing output results on an LCD Display or when connected to any smart phone with full productivity unleashed by the Schmidt Live app which significantly reduces the time required for testing and reporting.


Original Schmidt Live has multiple applications and is a favorite of the concrete and paper industries and in geology work.

  • Concrete: strength estimations, formwork removal and to complement core testing.
  • Paper: roll profiling in mills and converter plants.
  • Geology: strength testing, ageing, weathering (field and lab).

Frequently Asked Questions (1 answered questions)
There are predefined charts available to correlate rebound number with compressive strength , also we can define customize curves to obtain a relationship between rebound number and compressive strength.
Rebound number is required to calculate the compressive strength to verify the grade of concrete. Digital hammers are fed with predefined algorithms which directly converts the rebound value to compressive strength.
