3nh NH310+ Handheld Colorimeter and Color Meter (Φ8mm/Φ4mm)

3nh NH310+ Handheld Colorimeter and Color Meter (Φ8mm/Φ4mm)

In industrial manufacturing quality control workflows, monitoring and early detection of color deviations between batches is a key factor in helping businesses minimize defective products and maintain solid trust with partners. However, measuring color on complex surfaces—ranging from large flat substrates to curved, ultra-small components—has always been a challenging problem. The 3nh NH310+ handheld colorimeter stands as a comprehensive solution—a premium color measurement device integrating dual smart apertures to deliver absolutely precise color quantification results.

Overview of the 3nh NH310+ Colorimeter

The 3nh NH310+ is a premium tier handheld portable colorimeter from the 3nh brand. The device utilizes an international standard 8/d optical geometry (8-degree illumination angle, diffuse viewing), enabling objective material color evaluations that eliminate subjective human visual errors.

Equipped with a high-speed core processing chip and an ultra-sensitive photoelectric matrix sensor, the 3nh NH310+ delivers incredible repeatability and stability across consecutive measurement sessions. Notably, its configuration integrates both Φ8mm and Φ4mm measuring apertures, ready to flexibly handle sample surfaces of all sizes.

Key Features of the 3nh NH310+

💡 Outstanding Flexibility with Smart Dual Φ8mm and Φ4mm Apertures

Enterprises no longer need to endure the high expense of investing in multiple separate devices. With the NH310+, technicians can flexibly interchange measuring apertures based on product characteristics:

• Φ8mm Aperture (Standard): Optimized for flat, large-surface areas such as woven fabrics, molded plastic sheets, processed leather hides, and architectural wall paint surfaces.
• Φ4mm Aperture (Extended): Dedicated for small components, complex curved surfaces, electronic parts, garment buttons, or narrow packaging labels.

💡 Proprietary Dual Camera Viewfinder and Illumination Locating Technology

To completely eliminate measurement discrepancies caused by off-center alignment on small parts, the 3nh NH310+ comes equipped with a dual locating system:

• Camera Locating: Displays the actual target measurement zone in real time directly on the screen, enabling technicians to align perfectly.
• Illumination Locating: Projects a concentrated light spot at the exact center of the measurement point, making operations quick and perfectly centered.

💡 Exceptional Stability and Automated Calibration Capabilities

Thanks to its upgraded core algorithm, the NH310+ achieves an exceptionally small standard deviation for repeatability (Delta E*ab below 0.06), ensuring continuous data consistency. Upon startup, the instrument features automated white and black calibration, allowing engineers to confidently conduct field audits throughout the day without data value drift.

💡 Diverse Color Spaces and Ultra-Fast Pass/Fail Quality Auditing

With a simple scanning operation taking less than 1 second, the gage automatically computes and displays:

• Standard Color Spaces: CIE Lab, XYZ, LCh, RGB, CIE LUV.
• Advanced Chromaticity Indices: Whiteness, Yellowness, Color Fastness.
• Color Difference Formulas: Delta Eab, Delta Ecmc, Delta E00, Delta E94.
• Intelligent Warning Mode: Automatically compares readings against the target master standard and intuitively triggers a “Pass” or “Fail” alert, accelerating the screening of defective items directly on production lines.

💡 PC Software Connectivity for In-Depth Color Management

The device features an expansive internal memory capable of logging thousands of color data entries. Via its built-in USB port, the NH310+ synchronizes perfectly with specialized color management software on a computer, supporting color deviation trend charts tracking, international color card library management (Pantone, RAL), and professional quality control documentation (QC Reports) exporting to send to partners.
