Manufacturer: Phase II Plus Brand: Phase II Plus Model: SRG-4500

The latest in state-of-the-art surface roughness testers profilometer, the SRG-4000 is designed with the shop environment in mind. These surface roughness testers profilometer are distinguished by a high level of accuracy, multiple parameters and simplicity of operation. Extremely sensitive and highly accurate readings from this Phase II surface roughness tester are offered via multiple surface roughness profilometer parameters, Ra, Rq(Rms), Rt and Rz. The diamond stylus is hypersensitive and sophisticated enough to allow for a .001 (um) micron display resolution. The SRG-4000 surface roughness testers profilometer utilize an easy interface to allow for changes of in/mm (uin/um), cutoff length, sampling length, parameters, level of test(stylus position), digital filters and more! Measurement results are displayed as large characters on the LCD screen for easy recognition.

Manufacturer: Starrett Brand: Starrett Model: SR100

The Starrett SR100 surface roughness tester is a portable, handheld device with contact operation used to measure surface roughness, and has a control unit, a traverse unit, automatic calibration, a calibration standard, a diamond stylus, and an LCD screen that displays roughness average (Ra), average peak to valley height (Rz), maximum profile valley depth (Rv), maximum profile peak height (Rp), and total height of profile (Rt) measurements. The control unit and traverse unit can be used connected or remote from each other. The units communicate with an infra-red (IrDA) link for cable-free operation up to a distance of 40"/1m. Measurement results are saved in the control unit until the next measurement is taken. There is a five second cycle time between measurements. A mode button switches the tester between inch and metric readout. The tester also displays error codes as needed, such as when the unit needs calibrating. The tester range is 8000μin/200μm and the resolution is 2μin/0.05μm. The display resolution is 0.4μin/0.01μm for roughness average (Ra) and 1μin/0.1μm for Rz, Rt, Rp, and maximum profile valley depth (Rv). The traverse unit has a diamond stylus with a radius of 123μin /5μm nominal, a 90 degree tip angle, and a skid radius of 0.394"/10mm nominal. The stylus has a force of 1gf/10mN maximum at mid-range. The tracer tip has a radius of 200μin. The traverse length is 0.2"/5mm with a measurement length of 0.16"/4mm. The tracing speed is 0.08"/2mm per second. The filter used is a 2CR filter. The cut-off is 0.03"/0.8mm + or – 15%. The sample spacing is 0.025μin/1μm. The control unit uses one 3V CR 2450 battery, and an automatic shut-off feature turns off the display after five minutes of inactivity to extend battery life. The traverse unit uses three 3V CR 2450 batteries for a minimum life of 5,000 measurements, and an automatic shut-off feature powers down the unit after five minutes of inactivity to extend battery life. An indicator light alerts when batter...
