TR100 Plus Digital Roughness Tester for Surface Finish Inspection in Manufacturing

The Portable surface roughness tester TIME TR100 Plus surface roughness tester is designed with an advanced micro-processor, performs data acquisition, data processing and display of all test measurements.

Reliable handheld surface roughness measurement for on-site inspection

This portable surface roughness tester is built around an advanced micro-processor that ensures accurate data acquisition, fast processing, and clear display of measurement results. Designed for practical field and workshop use, the TIME TR100 Plus combines durability, precision, and ease of operation in a compact handheld format.

Integrated design and versatile measurement capability

The instrument features an integrated process with a built-in sensor and dual high-contrast OLED displays for excellent readability from multiple viewing angles. Users can quickly switch between Ra and Rz roughness parameters, making it suitable for a wide range of surface quality evaluations.

Adapted for complex surfaces and recessed areas

In addition to flat, round, and sloping surfaces, this “new model” is capable of measuring grooves and recessions up to 3.1 x 1.2 in (80 x 30 mm). This makes it especially useful for inspecting machined components where access is limited or surfaces are not uniform.

Typical applications and user benefits

The TIME TR100 Plus is commonly used in machining, metal fabrication, quality control, and maintenance environments. Users value its robust metal frame, straightforward calibration, and compliance with ISO / DIN standards. Compared to many entry-level roughness testers, it offers enhanced measurement flexibility, better display visibility, and reliable repeatability for routine industrial inspections.

The Portable Surface Roughness Tester TR100 is used by quality control technicians, machinists, and maintenance professionals to measure surface finish on metal, plastics, and machined components. Portable roughness testers provide standardized Ra and Rz surface finish values that help manufacturers verify machining quality and ensure parts meet design specifications, a critical part of quality assurance in precision fabrication.

Professionals praise the TR100 for its ease of use, quick readings, and compact design that supports on‑site roughness evaluation without transporting parts to a metrology lab. Compared with manual comparison charts, this instrument delivers quantified surface finish data that improves quality control workflows in manufacturing, inspection, and maintenance applications.
