Mikrosize – Your Trusted Partner for Precision Measuring Instruments, Featuring the Advanced Portable Spectrophotometer
In the fields of industrial quality control, material research, and production process monitoring, accurate color measurement is essential. Mikrosize, a leading supplier of precision measuring and testing instruments, offers a comprehensive range of solutions including hardness testers, video measuring systems, microscopes, and metallographic equipment. Our commitment to metrology excellence extends to color science with the introduction of the iColor‑T407 portable spectrophotometer – a compact, high‑performance device designed for on‑site and laboratory use. This instrument delivers reliable, objective color data, replacing subjective visual inspection and ensuring consistent quality across batches and supply chains.
Product Overview – Portable Color Measurement Redefined
The iColor‑T407 is a handheld spectrophotometer developed with proprietary spectral division core technology. It adopts the D/8° (diffuse illumination, 8‑degree viewing angle) geometric optical condition, supporting both SCI (specular component included) and SCE (specular component excluded) measurement modes. The device can be used independently or connected to PC/APP software, offering great flexibility. It is equipped with multiple measuring apertures (8 mm platform, 4 mm platform, and 1×3 mm) to accommodate various sample sizes, making it ideal for industries such as plastics, electronics, paints, inks, textiles, printing, ceramics, and more. It fully complies with international and national standards including CIE No.15 and GB/T 3978.
Core Features – Precision and Portability Combined
High‑precision optical system – Utilizes a planar grating spectrometer and a large‑area silicon photodiode array sensor (40 pairs of dual columns), achieving optical resolution better than 10 nm. The wavelength range covers 400 nm to 700 nm (for the T407 model), with a reflectance range of 0 % to 200 %.
Intelligent illumination – Powered by a combined full‑spectrum LED lamp and a UV lamp, the instrument ensures stable and consistent light output. The UV source is particularly important for measuring fluorescent whitening agents and optical brighteners commonly found in papers, textiles, and plastics.
Versatile measurement modes – Supports single measurement and average measurement (2 to 99 times). Users can select from 41 illuminants (including D65, A, C, D50, F series, etc.) and observer angles of 2° or 10°. The system can measure multiple color spaces: CIE LAB, XYZ, Yxy, LCh, CIE LUV, s‑RGB, HunterLab, Munsell, and more, plus color difference formulas such as ΔEab, ΔE00, ΔEcmc, ΔE94, and DINAE99.
Rich colorimetric indices – Beyond basic L*a*b*, the instrument provides whiteness (ASTM E313, CIE/ISO, AATCC, Hunter, etc.), yellowness (ASTM D1925, E313), metamerism index, staining fastness, color strength, opacity, 8° gloss, 555 index, blackness (My, dM), and CMYK density – many of which can be accessed via the accompanying software.
User‑Friendly Design for Real‑World Applications
Compact and lightweight – With dimensions of only 114 mm × 70 mm × 208 mm and weighing approximately 435 g (excluding the calibration base), the iColor‑T407 is easily carried to production lines, warehouses, or remote sites.
Intuitive operation – A 3.5‑inch TFT true‑color capacitive touch screen provides a clear interface, supporting multiple languages (Simplified Chinese, Traditional Chinese, English). The system includes a buzzer for measurement alerts and an adjustable screen backlight timer.
Powerful battery and connectivity – The built‑in 3.7 V / 5000 mAh lithium battery enables up to 8,500 measurements within 8 hours on a full charge. Charging and data transfer are handled via a universal Type‑C port, and Bluetooth® (optional) allows wireless connection to printers or mobile devices.
Ample storage – The internal memory holds 500 standard samples and 20,000 test records (each record can include SCI+SCE data simultaneously). Data can also be expanded via APP/PC mass storage.
Robust calibration – The non‑contact automatic whiteboard calibration system ensures long‑term stability and traceability. The calibration box also protects the standard whiteboard from dirt and damage.
Advanced Software and Data Management
The iColor‑T407 is supported by a comprehensive software ecosystem compatible with Windows, Android, iOS, Harmony OS, and even WeChat mini‑programs. Key software capabilities include:
Real‑time spectral curve and color difference graph display
PASS/FAIL judgement with user‑definable tolerances
Automated measurement and data uploading for online inspection
Customizable PDF report generation (including company logo, test standards, sample info)
USB and Bluetooth communication with <0.5 s transmission delay
Data can be printed via USB or Bluetooth printers (optional) for on‑site record keeping. The device also supports camera framing positioning and stable film positioning to ensure accurate sample alignment.
