Surface roughness tester R-130, R-135

portablewith LCD display

Handheld surface roughness tester for external surfaces and grooves The devices R-130 and R-135 are cheap, easily portable roughness gauges for surface inspections. During the measurement procedure the sensor moves linearly along the traverse length. The probe moves accordingly to the profile on the traversing length. These movements are converted into electric signals which are amplified, filtered and converted into digital signals by an A/D converter. These signals are then refined in the main processor as Ra and Rz values and displayed on the screen. Features and equipment Rotating probe for measuring in 3 different directions Ra and Rz parameters can be displayed after each measurement Portable printer and stand as accessory Cut-off: 0.25mm / 0.8mm / 2.5mm (cut-off wavelength) Number cut-off adjustable to 1-3-5 times (at 0.8 and 2.5mm) Filter: ANSI 2RC Measuring principal: piezo-electric Probe diamond: 90o / tip radius of 10 microns and 5 microns (standard) Robust aluminum housing RS232 connection (R-135) for transmitting data to a specific printer or computer Option: cable Maximum tracking force: 1500mp/15.0mN Power supply: 9V battery (Alkaline) Battery capacity: up to 3000 measurements Application Detects the roughness of hard surfaces, as well as inside holes, openings and grooves For example at: Labs, measuring rooms, workshops, engineering facilities, and many more
