Advancing with Technology 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” thickness range Road layer thickness measurement

StratoTest 4100 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. For road inspection The easy to operate StratoTest provides quick and accurate readings without the need of...

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. A new searching mode now enables the simple, safe and quick location of the reflectors ¡. Acoustically via headphones (audible also during street noise) ¡. Optically by an analogue indication of the minimum ¡. Digitally by an indication of the lowest reading The...
