The Phase II SRG-4000 Surface Roughness Tester / Profilometer is a high-precision, portable instrument engineered for evaluating surface texture directly on the shop floor. Designed with ease of use and accuracy in mind, the SRG-4000 features a hypersensitive 5μm diamond stylus and supports multiple roughness parameters, including Ra, Rq (RMS), Rz, and Rt. Its menu-driven interface and large LCD screen provide a clear and intuitive user experience.
The unit offers selectable cutoff lengths of 0.25mm, 0.8mm, and 2.5mm, and includes advanced filtering options such as RC, PC-RC, Gaussian, and D-P. The digital display features direct parameter readout, stylus position indicator, and battery level monitoring. Measuring results are compliant with ISO, DIN, JIS, and ANSI standards, ensuring compatibility with global quality requirements.
Built for mobility, the SRG-4000 operates on a rechargeable battery and includes RS-232 output for connection to a printer or PC. The rugged carrying case, NIST-certified reference standard, and instruction manual are included for on-the-go quality control and calibration support.
Ideal for machinists, inspectors, and quality control professionals, the SRG-4000 delivers accurate, repeatable surface finish readings on materials ranging from metals to composites. Optional accessories such as a 2μm stylus, extension rod, and mounting stand are available to expand application capabilities.
