3nh NR100 Precision Colorimeter (8/d; Φ8mm; Φ4mm)

3nh NR100 Precision Colorimeter (8/d; Φ8mm; Φ4mm)

In the industrial manufacturing quality management workflow, maintaining color consistency between batches is a vital element to preserve a business’s reputation. However, real-world product shapes are highly diverse – ranging from large flat blanks to curved components and narrow miniature parts. Having to invest in multiple separate colorimeters to accommodate each specific size often causes high expenses for small and medium-sized workshops. The 3nh NR100 Precision Colorimeter is the comprehensive answer – a handheld instrument series integrating two smart switchable measuring apertures in a single body, bringing a flexible color digitization solution with the most optimal investment cost on the market.

Overview of the 3nh NR100 Precision Colorimeter

The 3nh NR100 is a standard entry-level handheld colorimeter optimized by the 3nh brand for rapid check (Quick Check) capabilities directly across workshops, warehouses, or QC rooms. The device utilizes the international standard d/8 optical geometric structure (diffuse integrating sphere illumination, 8-degree viewing angle), fully meeting the stringent regulations of CIE standards.

What makes the NR100 one of the most preferred mobile color inspection instruments lies in its stable dual-optical path design combined with a minimalist one-touch operation. Workshop operators can easily trigger a measurement to accept color difference results in less than 1 second without having to go through complex in-depth setup steps.

Outstanding Features of the 3nh NR100

💡 Maximum Flexibility with Two Interchangeable Measuring Apertures (Φ8mm & Φ4mm)

Businesses no longer have to worry about investing in two individual instruments. With the NR100, technicians can easily switch the measuring aperture depending on the geometric characteristics and dimensions of the product:

• Standard Aperture (Phi 8mm): Optimized for flat surfaces with large areas such as molded plastic panels, flat leather sheets, woven fabric rolls, or standard flat matte paint films.
• Extended Small Aperture (Phi 4mm): Dedicated to narrow angular details, mini electronic components, buttons, plastic bottle caps, cosmetic tubes, or complex curved surfaces where large measuring heads are prone to light leakage.

💡 Stable International Standard d/8 Optical Structure

The instrument utilizes a premium d/8 diffuse integrating sphere optical geometry, which distributes the light source evenly over the sample surface. This smart optical path, combined with a highly sensitive photodiode sensor, enables the device to accurately measure core chromatic values, automatically minimizing error interferences caused by slight gloss or matte/rough textures of the material surface.

💡 Intuitive Target Area Positioning via Illumination Indicator

To completely eliminate errors caused by misaligning the measuring head (especially when measuring small and narrow details with the Phi 4mm aperture), the 3nh NR100 integrates a built-in illumination positioning technology that indicates a clear light spot at the center of the test point. Technicians can easily align and fit the measuring head perfectly flush against the target area, eliminating external ambient stray light leakage.

💡 Ultra-Fast Operation and Intuitive Pass/Fail Evaluation

The NR100 is widely known as an instant color measurement device due to its lightning-fast processing speed. With a single operation of placing the device and pressing a single trigger button:

• The machine instantly delivers intuitive CIE Lab color coordinate results right on its sharp display screen.
• It automatically calculates the Delta E*ab color difference index between the actual sample and the reference standard.
• It displays smart alerts based on pre-set tolerance settings, helping workshop operators instantly recognize whether a product is Pass or Fail to rapidly screen defective parts directly on the production line.

💡 Intensive Data Management PC Software Connection

Via a USB data transmission port connection, the NR100 synchronizes perfectly with intensive color management software on computers. The system assists enterprises in storing standard sample data, managing digital color card libraries, tracking chromatic trend charts, and automatically exporting professional Quality Control Reports (QC Report) to send to major partners.
