TROTEC BB20 Coating Thickness Gauge

The BB20 coating thickness meter can help you to sort out the good guys from the bad by providing you with reliable and accurate information on varying paint thickness – a sure sign that either repair work has been carried out on the car that you have set your sights on or that a part or panel has been replaced. In both cases the bodywork would have had to be resprayed. And that’ s what the BB20 can detect. But the BB20 is not only ideal for car dealerships, used car salesmen or quite simply anybody who is interested in buying a second-hand car. The BB20 can also be used to determine the thickness of many other coatings and can be used to check if work on railings, boats or countless other objects have been carried out satisfactorily and if protective coatings, for example, have been applied thickly enough. Ideal for:   paint thickness checks on used cars to see if repairs have been carried out after an accident   checking coating thicknesses on railings, boats etc. and to check that protective coatings have been applied correctly Technical Data:   Sensor: Ferromagnetic surfaces   Functioning principle: Magnetic induction   Guaranteed tolerance: ( ± 3 % + 1) µ m of the measuring value   Bending radius minimum ( surface) : 1.5 mm   Smallest measuring area: Ø 7 mm   Critical primary layer thickness: 0.5 mm   Sensor: non-ferrous metallic surfaces   Functioning principle: Eddy current   Guaranteed tolerance: ( ± 3 % + 1.5) µ m of the measuring value   Bending radius minimum ( surface) : 3 mm   Smallest measuring area: Ø 5 mm   Critical primary layer thickness: 0.3 mm   Measuring range: 0 to 1.250 µ m   Accuracy: max. 0.1 µ m   Functions: Maximum value, minimum value, average value and standard deviation, alarm function, backlight, auto power off   Dimensions / Weight: 110 x 54 x 24 mm / 100 g ( incl. battery)   Scope of delivery: Measuring device, calibrating accessories, storage case, battery, operating instructions
