Manual ## Features - Applications: Widely used in production site to measure surface roughness of various machinery-processed parts, calculate corresponding parameters according to selected measuring conditions and clearly display all measurement parameters. - Small in size, light in weight and easy to use. Highly sophisticated inductance sensor.Four wave filtering methods : RC, PC-RC, GAUSS and D-P. Built-in lithium ion rechargeable battery and control circuit with high capacity. - Be compatible with four standards of ISO, DIN, ANSI and JIS. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism inside the tester. The sensor gets the surface roughness by the sharp built-in probe. - This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then outputs the measurement results on LCD. ## Images ![TR-Z-SRT-6210 Portable Surface Roughness Tester Surftest Profilometer 4 Parameters Ra, Rz, Rq, Rt - Image 1](https://m.media-amazon.com/images/I/61XrT+T4WaL.jpg) ![TR-Z-SRT-6210 Portable Surface Roughness Tester Surftest Profilometer 4 Parameters Ra, Rz, Rq, Rt - Image 2](https://m.media-amazon.com/images/I/51yPAP98BCL.jpg) ![TR-Z-SRT-6210 Portable Surface Roughness Tester Surftest Profilometer 4 Parameters Ra, Rz, Rq, Rt - Image 3](https://m.media-amazon.com/images/I/61K1-idarxL.jpg) ![TR-Z-SRT-6210 Portable Surface Roughness Tester Surftest Profilometer 4 Parameters Ra, Rz, Rq, Rt - Image 4](https://m.media-amazon.com/images/I/617d82prAYL.jpg) ![TR-Z-SRT-6210 Portable Surface Roughness Tester Surftest Profilometer 4 Parameters Ra, Rz, Rq, Rt - Image 5](https://m.media-amazon.com/images/I/51K72xPyk2L.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/53003680-tr-z-srt-6210-portable-surface-roughness-tester-surftest-profilometer](https://www.desertcart.pl/products/53003680-tr-z-srt-6210-portable-surface-roughness-tester-surftest-profilometer) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-08*
