Physical specifications and utilities

Electrical supply	Approx. rechargeable internal battery; charger 100–240 V AC, 50/60 Hz; build-dependent.
Power / connected load	Approx. 5–20 W connected load for preliminary planning.
Overall instrument dimensions	Approx. 90 × 90 × 230 mm (W × D × H).
Instrument weight	Approx. 0.5–1 kg net.
Gross / shipping weight	Approx. 2–4 kg gross; estimated packing allowance.
Interfaces	USB, Bluetooth; Windows and mobile app.
Lab requirements	Clean, dust-free workspace; specimens are conditioned per the selected method.

Dimension order and approximate values are stated in each row. Packaging data are separate from instrument dimensions and net mass. Approx. rows are preliminary engineering estimates based on comparable equipment and function/capacity; they are not verified manufacturing measurements or standard requirements. Installation and shipment are finalised against the approved drawing and nameplate. Estimate scope: base product / one unit; external computer, bench and auxiliary plant excluded.

Specifications, dimensions, and power requirements are approximate and subject to change without prior notice for continuous design improvements.

Product technical specifications and images may vary according to manufacturing conditions and applicable standards.

Test and configuration

Measured output / function: Spectral reflectance, colour coordinates and colour difference (ΔE*ab)
Parameters selected for the method: Geometry (SCI/SCE), aperture, illuminant and observer
Verification points: Calibration, repeatability and reference sample

Listed methods are application references. Suitability is established by assessing the selected hardware, current method and calibration together.

Control and recording specification

The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.

Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
Measuring geometry (SCI/SCE), aperture, illuminant and observer are written to each measurement record; the colour-difference formula is stated in the report.
Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.
