1 echanical and electronic length measuring instruments for internal and external measurements

2 Precision and continuity Features Contents ver since its foundation in 1883 Kroeplin have been involved in development and production of handy reliable and precise gauges for the measurement of lengths and thicknesses, especially for the metalworking industry. Thus the quick test system was created, which was the basis for all further innovations and also for the electronic dial indicators. xperience is the solid foundation for quality. Careful observation and analysis of the market, flexible realization of requirements, convincing measuring concepts - that is the philosophy that makes Kroeplin successful. Today like before, for more than 125 years. Certificate of quality Reliable repeatability Scales are well arranged and easy to read Scale interval from 0,005mm up Tolerance marks easy to read All mechanical gauges are also available in INCH The electronic gauges can be switched over to INCH easuring contacts are mainly made of carbide lectronic gauges with analog / digital display for better reading itutoyo interface USB interface rgonomically designed easuring programs and contacts for different applications Absolute and relative measurement Red / Green LD for tolerance measurement Special solutions possible Stand holding unit for serial measurement of small parts Internal measurement Application range up to 60mm Application range up to 120mm Application range exceeding 120mm Internal comparison measurement Internal measurement with 3-point contact Internal measurement for blind holes xternal measurement Application range up to 30mm Application range up to 200mm Tube wall measurement Application range up to 100mm easurement of foamed material and foils Application range up to 100mm Convincing price for convincing performance Accessories / Interfaces 22 Special gauges / Definitions 23 Detailed information and data sheets for all gauges are available on our webpage Subject to technical alterations

3 NW! Instruments with 3-point contact for easier centering NW! rgonomically designed with new IP classification The gauges provide a digital / analog display for better reading. The quicktest gauges includes custom designed test programs, measuring contacts, absolute- and relative measuring programs and red/green display for tolerance measurement.

Terms of length test techniques see DIN 2257 part 1 and part 2 and International Vocabulary of Basic and General Terms in etrology. Foundations This instruction follows approximately the checking instructions of the German standard DIN 878 for dial gauges and the checking instructions for caliper gauges according to VDI/VD/DGQ 2618, page 13. The gauges are referred to as gauges with absolute measurement and adjustable zero point. Range of indication Azb The scale interval is the modification of the value of a measured variable that causes the modification of the indication by one interval. The scale interval is indicated in the unity of the measured variable. Deviation in the measuring range f The deviation in the measuring range f represents the distance of ordinates between the highest and the lowest position in the deviation diagram, when the movable caliper arm closes. The tolerance field G for f is symmetrically positioned to the zero line. Repeat precision fw The range of indication is the range between the highest and the lowest indication. easuring range eb The repeat precision fw is a characteristic value for deviations of the measured quantity within the measuring range in the same motion direction of the movable caliper arm (usually n=5). This margin of error is designated as repeat limit r. easurement of wall thicknesses at large undercuts with bayonet-type contacts (displacement in direction of the arrow before and after the measurement). The measuring range of a gauge represents the range of measuring values in which given error limits must not be exceeded. easuring span es The measuring span is the difference between starting value and final value of the measuring range. easuring force Fmin, Fmax When the caliper arm closes, the measuring force Fmax bzw. Fmin is determined at the top of the movable caliper arm. The gauge must be held in vertical position >= 200 mm
