COATING THICKNESS GAUGE The BB20 has an innovative dual sensor which enables you to measure the thickness of non-magnetic coatings like paint and varnishes, synthetic coatings, zinc coatings, enamel or chrome as well as steel or iron and non-iron metals like aluminum, magnesium, titanium etc. The measuring head is spring-mounted and has a practical V groove. This makes it easier to carry out measurements on rounded objects like axes or hinges and prevents vibrations from distorting or affecting the measuring results. The measuring device is extremely compact and can be used with one hand only. It has an impressive measuring range from 0 to 1,250 µm and guarantees precise measuring results with helpful statistical values and a practical alarm function which alerts the user when predefined thickness thresholds have been exceeded. These professional functions and features make the BB20 ideal for use in the auto­mo­tive sector where it can be used to inspect the bodywork of cars and check whether a car has been involved in an accident or a new coat of paint has been applied. It can also be used to check just about everything ranging from paint thickness on railings to the coats of paint on a boat or ship as well as other protective coatings. 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 Benefits in practice: Dual sensor designed to measure the thickness of non-magnetic coatings on all magnetic and non-magnetic metals Broad measuring range from 0 to 1,250 µm Alarm function that alerts the user when predefined thickness thresholds have been exceeded A variety of useful statistical functions like minimum, maximum or average coating thickness Two-point calibration for high level of accuracy Memory for up to 400 measuring values USB interface for PC measuring data transfer Can be used with one hand only Backlit display Auto power off Excellent value for money Technical Data: Sensor: Ferromagnetic surfaces Functioning principle: Magnetic induction Guaranteed tolerance: (±3% + 1) µm of the measuring value Bending radius minimum (surface): 1.5 mm Smallest measuring area: Ø 7 mm Critical primary layer thickness: 0.5 μm Measuring range: 0 to 1,250 µm Accuracy: max. 0.1 µm Sensor: non-ferrous metallic surfaces Functioning principle: Eddy current Guaranteed tolerance: (±3% + 1.5) µm of the measuring value Bending radius minimum (surface): 3 mm Smallest measuring area: Ø 5 mm Critical primary layer thickness: 0.3 μm Measuring range: 0 to 1,250 µm Accuracy: max. 0.1 µm Functions: Maximum value, minimum value, average value and standard deviation, alarm function, backlight, auto power off, memory for up to 400 measuring values Dimensions (height x width x depth) / Weight: 110 x 54 x 24 mm / 100 g (incl. battery)
