Horizontal Spectrophotometer TS-25D
TS-25D Horizontal Spectrophotometer | Selectable Apertures, UV, D/8 and Traceable Color Quality Control
The TS-25D horizontal spectrophotometer is part of 3nh’s advanced spectrophotometer series. It uses D/8 optical geometry, a dual optical path, combined full-spectrum LED and UV light sources, and SCI/SCE measurement modes. Select a Φ8 mm or Φ4 mm aperture before purchase. It is designed for laboratory color analysis, color-standard setup, incoming inspection, and traceable production quality control.
The TS-25D can be evaluated for color inspection in plastics and electronics, paints and inks, textiles and dyeing, printing, ceramics, packaging, research, and quality control. It supports spectral data, L*a*b* values and ΔE color-difference evaluation, supplier acceptance, and color-standard management. For fluorescent or optical-brightener-containing samples, or samples affected by special illumination, confirm the method against the sample, applicable standard, aperture, and internal QC procedure.
What applications suit the TS-25D?
Color control for plastics, electronics and components
Measure plastic housings, electronic components, molded parts, coated parts, and supplier materials to support batch comparisons and acceptance workflows.
Paint, ink and coating development
Evaluate coating formulations, ink colors, standard-color matches, and development samples. If surface gloss varies, confirm the SCI/SCE measurement conditions.
Textile dyeing and print color control
Compare fabrics, dyed materials, printed products, and packaging. For fluorescent materials, optical brighteners, or unusual light responses, confirm UV and measurement conditions.
Ceramics, coatings and flat samples
For mostly flat materials with measurement areas suited to a Φ8 mm or Φ4 mm aperture, evaluate the TS-25D for stable color measurement and process QC.
TS-25D key advantages
Choose an aperture for the application
Before purchase, assess the Φ8 mm or Φ4 mm version against sample size, measurement area, and QC requirements.
UV, D/8 and SCI/SCE
D/8 geometry and SCI/SCE modes support color checks with or without the effect of surface gloss; UV needs can be evaluated for the sample.
Dual optical path for stable measurement
The dual optical path can be evaluated for measurement stability and use across different materials, including ongoing QC tracking.
Traceable quality data
Use it to support R&D comparisons, process sampling, pre-shipment checks, supplier batch management, and internal color standards.
TS-25D feature details
High-performance detector array
Manufacturer information describes a dual 40-element silicon photodiode array with a larger sensing area. It provides a basis for spectral data capture, color evaluation, and batch comparison. Actual performance depends on the sample, calibration, and QC workflow.
Combined full-spectrum LED and UV light sources
The current TS-25D configuration confirmed by Fulcrum Technology includes combined full-spectrum LED and UV sources. Evaluate UV-included or UV-excluded conditions for the inspection. For fluorescent materials, optical brighteners, or special coatings, confirm the method using sample details.
Repeatability and instrument agreement
Manufacturer information indicates repeatability and instrument-agreement control. This may support comparison across instruments, sites, and long-term QC. Confirm actual results against calibration status, samples, and measurement procedures.
Multiple color indices
In addition to L*a*b* and ΔE, evaluate whiteness, yellowness, metamerism, spectral and color-difference charts, pass/fail results, and color trends according to the supplied version and software.
Camera viewfinder positioning
The built-in viewfinder helps operators check the measurement area and reduce variation from misplaced measurement points. Confirm positioning and aperture requirements for local points, patterns, color patches, printed areas, or small regions.
Compact horizontal design
The horizontal design can reduce operator movement during measurement. It suits laboratory standards, R&D comparisons, and production sampling. For curved, irregular, or small samples, confirm fixtures and point stabilization.
Dual optical path with algorithm
The dual optical path and algorithm can be evaluated for interference resistance, measurement stability, and use across different samples. For powders, textured, curved, small, or uneven surfaces, provide sample details to confirm a suitable fixture and method.
Multiple color spaces
Evaluate CIE LAB, XYZ, Yxy, LCh, CIE LUV, s-RGB, HunterLab, and Munsell data for R&D comparisons, color-standard setup, and communication across QC teams.
Select a Φ8 mm or Φ4 mm aperture
Select the aperture before purchase. A Φ8 mm aperture may suit larger measurement areas, while Φ4 mm may suit smaller or local areas. Confirm the choice against sample size, measurement point, and QC requirements.
3.5-inch color touchscreen
The 3.5-inch color touchscreen helps operators review color values, color differences, and measurement information in QC rooms, laboratories, and production sampling.
User-friendly operation
The interface is intended for routine color measurement and data review by QC, R&D, and production personnel. Confirm operating procedures through internal QC requirements and training.
Single and average measurement modes
Choose a single reading for quick checks or general comparison. Average measurement may help with uneven or textured surfaces or where point-to-point variation needs to be reduced. Confirm the number of readings for the sample and QC procedure.
SQCX quality-management software
Depending on the supplied version, SQCX software can be evaluated for organizing color data, comparing color differences, and exporting test reports for QC records, supplier batch comparisons, and internal color-standard management.
How do TS-26D, TS-25D and TS-23D differ?
For three aperture options, flexible measurement points, or small-area measurement, evaluate the TS-26D. If you want to choose a Φ8 mm or Φ4 mm aperture before purchase, consider the TS-25D. If your measurement area is mainly suited to a fixed Φ8 mm aperture, compare the TS-23D. Confirm selection against sample size, point size, surface, measurement purpose, and QC process.
Related spectrophotometer options
Compare more advanced models in the advanced handheld spectrophotometer or 3nh handheld spectrophotometer categories. For fixed laboratory measurement, consider advanced benchtop spectrocolorimeters; for quick color-difference checks, compare a colorimeter.
TS-25D frequently asked questions
Q1: What samples suit the TS-25D?
It can be evaluated for plastics and electronics, paints and inks, textiles, printing, ceramics, packaging, R&D, and QC. For small, curved, textured, or uneven samples, confirm aperture and method using sample details.
Q2: How does the TS-25D differ from the TS-26D?
The TS-25D offers a Φ8 mm or Φ4 mm aperture selected before purchase. The TS-26D has Φ8 mm, Φ4 mm, and 1 × 3 mm apertures for more flexible measurement points. Confirm selection against sample size and measurement purpose.
Q3: How should I choose between the TS-25D and TS-23D?
The TS-23D has a fixed Φ8 mm aperture for larger measurement areas and fixed conditions. The TS-25D lets you choose Φ8 mm or Φ4 mm before purchase when aperture choice needs to match sample area.
Q4: What are SCI and SCE used for?
SCI/SCE help assess how surface gloss affects color data. For glossy, matte, coated, or gloss-variable samples, confirm whether your internal standard uses SCI, SCE, or records both.
Q5: When should I consider the UV condition?
UV conditions can help evaluate color differences in fluorescent, optical-brightener-containing, or specially light-responsive materials. Confirm whether to include or exclude UV using sample characteristics, customer acceptance criteria, and QC procedures.
Q6: What information should I provide when requesting a TS-25D quotation?
Provide the material and sample size, measurement-area size, surface condition, gloss or fluorescence, color-difference formula, customer tolerance, SCI/SCE and UV needs, and record or reporting requirements. This helps Fulcrum Technology assess a suitable configuration.
Need to check whether the TS-25D fits your color QC workflow?
Share the material, measurement area, aperture needs, color-difference formula, SCI/SCE and UV conditions, and customer acceptance requirements. Fulcrum Technology can help assess the TS-25D or another 3nh spectrophotometer.
