NR145 Colorimeter (Single Aperture 8 mm; 45°/0°)
NR145 Colorimeter | 45°/0° Single 8 mm Aperture for Fast Color Comparison and Routine Quality Control
The NR145 colorimeter compares color differences between a reference and a sample, providing CIE Lab color data and common color-difference values such as ΔE, ΔL, Δa and Δb. It is suited to on-site quality checks, incoming inspection, in-process inspection and quick pre-shipment verification.
This portable model supports both battery and external power and includes a USB interface for connecting to a computer for data display and follow-up management. Suitability should be confirmed against the sample material and surface, measurement area, color uniformity and internal quality-control workflow.
NR145 Colorimeter Features
Designed for routine quality checks that need quick Lab data, ΔE results and on-site comparison.
Automatic Color-Difference Comparison
Automatically compares a sample with a reference and provides three CIE Lab values plus four color-difference values: ΔE, ΔL, Δa and Δb.
Two Measurement Modes
Provides sample-test and single-test modes for different inspection settings, test frequencies and on-site workflows.
Portable Design
Supports battery and external power, making it suitable for laboratory work, on-site inspection, production-line sampling and mobile measurements.
USB Connectivity
The USB interface connects to a computer for data display and supports field records, data review and quality follow-up.
Typical NR145 Application Scenarios
Incoming Inspection
Quickly compare raw materials, components and semi-finished goods with a standard sample.
In-Process Inspection
Sample production batches, track color differences and check color changes during processing.
Pre-Shipment Inspection
Check ΔE, ΔL, Δa and Δb differences between finished products and reference samples.
Rapid On-Site Decisions
Supports quality-control and acceptance workflows that require portable, quick color checks.
Selection and Use Guidance
The NR145 is intended for fast color comparison and routine quality checks. For samples with high gloss, rough texture, uneven color, or transparent or translucent properties, confirm the aperture, sampling locations, averaging method and internal acceptance criteria first. Applications requiring full spectral data, SCI/SCE switching, supply-chain color management or more complete color traceability may be better served by a spectrophotometer.

Selection Guidance
The NR145 is suited to quick color comparison, incoming inspection, in-process checks and routine quality control. For glossy, rough, unevenly colored, transparent or translucent samples, confirm the aperture, sampling points, averaging method and internal acceptance criteria. If full spectral data, SCI/SCE mode switching, supply-chain color management or more complete color traceability is required, consider a spectrophotometer.
