At ZORN INSTRUMENTS you will find a complete range of useful tools for quality assurance on the construction site.
This includes the flagship Lightweight Deflectometer ZFG for the quick testing of the load-bearing capacity of compacted soils. For higher degrees of compaction greater than 120 MN/m2 EV2, as need to be verified while applying ballast bearing courses for instance, ZORN INSTRUMENTS has developed the Medium Heavy Falling Weight Deflectometer with double impact force. Within a very short time, even inexperienced users can test, print out and archive the quality of the soil compaction using the handy tester.
There are also Lightweight Penetrometers for soil investigation, the Static Plate Load Tester according to DIN 18134, a device for dynamically determining the CBR (California Bearing Ratio) value, the modified Lightweight Deflectometer for determining the suitability for traffic of asphalt (Asphalt Tester) or the only precise Measuring Wedge for measuring the flatness of road surfaces according to the test standard TP Eben - Berührende Messungen (Technical test specification Evenness - contiguous measurements).
