The 3nh NH310 Portable Colorimeter provides color difference measurement with interchangeable 8 mm and 4 mm apertures, camera-assisted positioning and three selectable illuminants.

It supports routine color quality control in plastics, paints, printing, automotive components and textiles, helping users compare production samples with stored reference standards.

The two standard apertures accommodate different sample sizes. Use the 8 mm aperture for larger measurement areas or the 4 mm aperture when the available surface is smaller. Camera locating provides a view of the target area, while illumination locating helps align the measurement opening. An optional extended 8 mm aperture provides access to suitable concave surfaces.

D65, D50 and A illuminants allow users to evaluate color values under different reference lighting conditions. The instrument supports CIE LAB, XYZ, LCh, RGB and LUV color spaces, along with whiteness, yellowness and color fastness evaluation. Multiple color difference formulas help users select an evaluation method appropriate to their quality control procedure.

Automatic white and black calibration at startup prepares the instrument for measurement. Onboard storage holds 100 standards and 20,000 samples, supporting repeated comparisons with reference colors. A rechargeable lithium-ion battery provides more than 3,000 measurements per charge, according to the manufacturer.

USB connectivity and CQCS3 quality control software extend the workflow to a computer. Software functions include color difference analysis, cumulative color difference analysis, chromaticity index evaluation, color sample database management and color simulation.

Key Features

• Two standard apertures: Interchangeable 8 mm and 4 mm openings accommodate larger surfaces and smaller measurement areas.
• Dual positioning methods: Camera and illumination locating help place the measurement opening on the intended sample area.
• Three illuminants: D65, D50 and A support evaluation under different reference lighting conditions.
• Multiple color outputs: CIE color spaces, color difference formulas and additional indices support varied inspection requirements.
• Repeatability: Standard deviation within 0.06 ΔE*ab under the manufacturer's white-plate test conditions.
• Reference and sample storage: Memory holds 100 standards and 20,000 samples.
• PC analysis: CQCS3 software supports sample management and expanded color quality control analysis.
• Portable power: Rechargeable 3.7 V, 3,200 mAh lithium-ion battery.

Applications

Use the NH310 to compare production samples with approved reference colors, check color differences between batches and document results during incoming inspection or product development. Suitable sample categories include plastic parts, painted surfaces, printed materials and textiles. Select an aperture that fits fully within a representative measurement area and use consistent sample preparation and positioning.

Extended 8 mm aperture: Optional measurement attachment for accessing suitable concave surfaces. It is separate from the standard 8 mm and 4 mm apertures.

Accessories

Standard measuring apertures: 8 mm and 4 mm.

Optional accessory: Miniature thermal printer.

How does the NH310 differ from the NH300?

The NH310 adds a 4 mm aperture alongside the 8 mm aperture, camera-assisted positioning and D50 and A illuminants in addition to D65. It also offers additional color spaces and evaluation functions. Its specified white-plate repeatability is within 0.06 ΔE*ab standard deviation, compared with 0.07 ΔE*ab for the NH300.

Which aperture should I use?

Choose the aperture that fits within a representative area of the sample. The 4 mm opening is useful when the available measurement area is too small for the 8 mm opening.

Do I need to recalibrate after changing apertures?

Yes. After installing the required aperture, select the corresponding aperture setting in the instrument menu and perform white and black calibration.

What is the purpose of camera locating?

Camera locating helps identify the target area before measurement, which is particularly useful when measuring a small section of a sample.

Can it measure concave surfaces?

An optional extended 8 mm aperture is available for suitable concave surfaces. Confirm that the attachment can access the sample and make proper measurement contact.

Can I save standards for future comparisons?

Yes. The NH310 stores up to 100 standards and 20,000 samples.

What does the PC software add?

CQCS3 supports color difference analysis, cumulative analysis, chromaticity index evaluation, sample database management and color simulation.

How many measurements can I take on one charge?

The manufacturer specifies more than 3,000 measurements per charge. Actual battery performance depends on operating conditions.
