Advancing with Technology Road layer thickness measurement StratoTest 4100 Thickness gauge for asphalt, slag and concrete materials • Non-destructive measurement • Immediate display of readings • Thickness range up to 40 cm/15” • Measurements repeatable at the same spot • Complete print-out of all site measurements New: Special probe for up to 80 cm/31” thic

the precise electronic measuring gauge On-site testing of pavement thickness Designed for on-site testing of pavement thickness, this most accurate electronic gauge provides immediate thickness readings of road layers during construction work. As a result, road layers can be paved more accurately and economically avoiding increased factor of safety for pavement thickness. At the same time, the risk of invoice deductions can be prevented when it comes to cost settlement. times. With real-time test reports being immediately at hand, the StratoTest proved to be the ideal gauge for road inspection....

The gauge probe takes the form of a disc-shaped coil assembly working on energised high frequency. As the probe approaches the aluminium sheet, the pick-up coil registers the field density, which in turn is directly related to layer thickness. The StratoTest evaluates the results immediately, displaying readings digitally in cm or inch. The stored data together with the readings and their calculated statistics can be transferred immediately or later to the portable printer MiniPrint or to a PC. Every stored reading can be found under the relative position number. With the supplied calibration...

StratoTest 4100 The following example shows the print-out with MiniPrint in SITE mode: Technical data eddy current testing Measurable layers: all non-metallic road layer materials aluminium foils or sheets of different sizes Measuring ranges: 0…40 cm (N400ST standard probe); 0…10 cm (N100ST optional probe); 0…80 cm (N800ST optional probe) Resolution of standard probe: 0.1 cm from 0…30 cm 0.2 cm from 30…35 cm, 0.4 cm from 35…40 cm Tolerance of standard probe: Tolerance ± (0.1 cm +2 % of reading) ± 2 % of reading ± 3 % of reading ± (0.1 cm +2 % of reading) ± 2 % of reading ± 2 % of reading Data...
