The SRG-4600 measures flat surfaces, inside and outside diameters, and grooves and recessions wider than 4 mm (0.16 in.). The instrument ships with a calibrated reference standard with support plate, Bluetooth auto-start unit, leveling plate, stylus protector, AC adapter, and rugged carry case. An optional micro printer, precision stand, and PC software are available as accessories, along with a full range of application-specific stylus options including deep groove, small hole, curved surface, and stylus extensions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNine Roughness Parameters with 0.001 µm Resolution\u003c\/strong\u003e - Measures Ra, Rz, Rq (Rms), Rt, Rs, Rsm, Rmax, Rpc, and Rmr with a 5 µm diamond tip inductance-type stylus, delivering resolution of 0.001 µm and accuracy within +\/- 10% across the full measurement range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth Wireless Auto-Start Standard\u003c\/strong\u003e - Bluetooth auto-start connectivity is included as standard, enabling wireless data transfer to a PC or compatible device without manual triggering - in addition to the USB output also provided.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Stylus Design with Wide Geometry Coverage\u003c\/strong\u003e - The external stylus assembly measures flat surfaces, inside and outside diameters, and grooves and recessions wider than 4 mm, with optional application-specific stylus tips available for deep grooves, small holes, curved surfaces, and extended reach applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour Selectable Digital Filters\u003c\/strong\u003e - Supports RC, PC-RC, Gaussian, and D-P filter types, providing the flexibility to match measurement filter selection to international standards and specific surface evaluation requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRechargeable Li-Ion Battery with Auto Shut-Off\u003c\/strong\u003e - Powered by a built-in rechargeable lithium-ion battery for extended untethered use, with automatic shut-off to preserve charge, eliminating the cost and inconvenience of disposable battery replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull ISO, DIN, JIS, and ANSI Standard Compliance\u003c\/strong\u003e - Supports all four major international roughness standards with switchable metric and imperial measurement units, making the SRG-4600 suitable for global manufacturing, multi-standard inspection workflows, and supplier qualification environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable xmlns=\"http:\/\/www.w3.org\/1999\/xhtml\" cellspacing=\"0\" cellpadding=\"0\" dir=\"ltr\" border=\"1\" data-sheets-root=\"1\" data-sheets-baot=\"1\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"190\"\u003e \u003ccol width=\"399\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Number\u003c\/td\u003e\n\u003ctd\u003eSRG-4600\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003ePhase2+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstrument Type\u003c\/td\u003e\n\u003ctd\u003eHandheld surface roughness gauge \/ profilometer with external stylus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRoughness Parameters\u003c\/td\u003e\n\u003ctd\u003eRa, Rz, Rq (Rms), Rt, Rs, Rsm, Rmax, Rpc, Rmr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRoughness Standards\u003c\/td\u003e\n\u003ctd\u003eISO, DIN, JIS, ANSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Range (Ra, Rq)\u003c\/td\u003e\n\u003ctd\u003e0.01 – 40 µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Range (Rz, Rt, Rm)\u003c\/td\u003e\n\u003ctd\u003e0.02 – 160 µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay Resolution\u003c\/td\u003e\n\u003ctd\u003e0.01 µm (+\/-20 µm range) \/ 0.02 µm (+\/-40 µm range) \/ 0.04 µm (+\/-80 µm range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/- 10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRepeatability\u003c\/td\u003e\n\u003ctd\u003eLess than or equal to 6%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStylus Tip\u003c\/td\u003e\n\u003ctd\u003eDiamond, 5 µm radius\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003eInductance type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePickup Force\u003c\/td\u003e\n\u003ctd\u003eLess than 4 mN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Drive Range\u003c\/td\u003e\n\u003ctd\u003e0.7 in.
