Professional Linshang Touch Screen Colorimeter Series (LS172, LS173, LS175) in Malaysia

For precision color measurement, digital color chart matching, automated quality control fast detection, and spectral reflectance analysis across textured materials, plastics, coatings, paper, and printing applications,having a versatile series of touch screen colorimeters with tailored apertures and illumination geometries is essential. MTM Precision Sdn. Bhd. is proud to present the official Linshang Touch Screen Colorimeter lineup (LS172, LS173, and LS175) in Malaysia.

The Linshang LS172 / LS173 / LS175 Series consists of three advanced handheld touch screen colorimeters equipped with a 3.5-inch IPS color capacitive display for an excellent operating experience. Featuring built-in standard electronic color charts, configurable color difference thresholds (Pass/Fail judgment), spectral reflectance curve display, and multi-formula calculation capabilities (

\Delta\text^*ab

\Delta\text^*00

,etc.), these instruments allow users to scan, match, and compare colors in seconds. Paired with a mobile phone APP for instant data sharing and powerful PC upper-machine software for batch analysis, the series covers diverse surface measurement needs through different optical geometries (

45^\circ/0

vs.

\text/8^\circ

) and aperture sizes (8mm vs. 20mm).

Below is an extensive technical breakdown of the product introduction, model comparison, key measurement features, applications, and detailed parameters for the LS172, LS173, and LS175 models, presented cleanly in plain text without tables, citations, or encoding errors.

Product Applications

LS175 Large Aperture (20mm) Applications: Color measurement and color difference evaluation for textured, rough, grained, or patterned surfaces such as textiles, leather, wood grain, plastics, and non-uniform materials
LS172 & LS173 Standard Aperture (8mm) Applications: Standard smooth surface color auditing for injection-molded plastics, paints, automotive coatings, paper sheets, packaging, and commercial printed materials
Quality Control (QC) Fast Detection: Setting custom color difference thresholds ( $\Delta\text$ setup) for automated PASS / FAIL evaluation on industrial production lines
Electronic Color Matching: Scanning target samples to identify the closest standard color codes across multiple integrated electronic color charts
Spectral Analysis: Viewing real-time spectral reflectance curves to analyze metamerism and precise spectral distributions

Key Features & Operational Advantages

3.5-Inch IPS Color Capacitive Touch Screen: High-resolution color screen delivering smooth,responsive touch interaction and clear data display from multiple viewing angles.
Built-in Standard Electronic Color Charts: Automatically matches measured colors against built-in electronic color libraries to quickly find the closest color card codes.
Color Difference Comparison & Threshold Setting: Displays standard values, sample values, and delta differences ( $\Delta\text^*$ , $\Delta\text{a}^*$ , $\Delta\text{b}^*$ , $\Delta\text^*$ ) with customizable tolerance thresholds for instant PASS / FAIL judgment.
Spectral Reflectance Curve Display: Visualizes reflection spectra across the visible light range (400nm to 700nm) for accurate color formulation and metamerism analysis.
Locating Plate Included: Supplied with a dedicated positioning locating plate to ensure precise measurement spot positioning on small or patterned target areas.
Dual Wireless & Wired Data Connectivity: Supports Bluetooth connection to iOS/Android mobile APPs for remote measurement and data sharing, as well as Type-C USB connection to PC software for archiving and report generation.

Model Comparison & Configuration Breakdown

Linshang LS172 (45/0 Geometry, 8mm Aperture):
- Illumination Geometry: $45^\circ/0$ ( $45^\circ$ annular illumination, $0^\circ$ viewing angle)
- Measuring Aperture: 8mm
- Best Suited For: Smooth, flat surfaces where visual perception under direct directional illumination is critical (e.g., printed paper, coatings, smooth plastics).
Linshang LS173 (D/8 Geometry, 8mm Aperture):
- Illumination Geometry: $\text/8^\circ$ , Specular Component Included (SCI)
- Measuring Aperture: 8mm
- Best Suited For: Glossy, metallic, or glossy/matte coating surfaces requiring total specular reflectance integration (e.g., paints, automotive parts, masterbatches).
Linshang LS175 (45/0 Geometry, 20mm Large Aperture):
- Illumination Geometry: $45^\circ/0$ ( $45^\circ$ annular illumination, $0^\circ$ viewing angle)
- Measuring Aperture: 20mm (Large Aperture)
- Best Suited For: Textured, coarse, grained, or patterned materials (e.g., textiles, fabrics, leather,wood, stone, textured plastics) where averaging over a larger area is necessary for stable readings.
