Practical Guide

Optical Excellence in the Laboratory: The Master Guide for the 3nh YS6002 Benchtop Color and Haze Meter

In modern quality assurance of plastics, films, glass, and liquids, subtle nuances determine product approval. The 3nh YS6002 Benchtop Color and Haze Meter combines high-precision spectrophotometry with standard-compliant haze measurement according to international standards. This practical guide shows you how to unleash the full potential of this high-end instrument, eliminate measurement errors, and generate reproducible quality data for your documentation.

Product Overview & Technical Flexibility

Parameter / Feature	YS6002 Model Specification	Practical Benefit for Users
Optical Geometry	Transmissive: d/0 (Diffuse illumination, 0° viewing) Reflective: d/8 (Model dependent)	Accurate haze and transmission measurements according to CIE standards. Prevents stray light interference.
Light Source & Sensor	360–780 nm Full Spectrum Combined LED & UV Excitation	Extremely durable (>3 million measurements), precisely simulating the D65 light source.
Measuring Apertures	Standard: Ø 25.4 mm (Optional micro-measurement down to Ø 4 mm)	High flexibility for changing sample geometries and ultra-small sample quantities.
Sensor Architecture	Concave Grating & Dual-Array 256-Pixel CMOS Image Sensor	Highest optical resolution and spectral separation within 10 nm intervals.

Laboratory-Grade Performance

ΔE*ab ≤ 0.03

Excellent Repeatability: Guarantees identical measurement results during multiple tests of the same sample.

154 mm

Integrating Sphere Diameter: Optimal light mixing for flawless haze measurements according to ASTM D1003/1044.

20,000+

Internal Memory Datasets: Maximum independence in standalone operation, including comprehensive QC sample management.

Practical Tip for Liquid Measurements: When analyzing chemical solutions or pharmaceutical fluids (e.g., Platinum-Cobalt or Gardner index), always use optically pure, specialized cuvettes. Even minimal fingerprints or micro-scratches on the glass will significantly distort haze and transmission values. Wipe the exterior with a lint-free microfiber cloth before every measurement.

Recommended Basic Settings for Standard Applications

Note: The following parameters serve as application-specific reference values and must be aligned with your internal testing protocols.

Standard Illuminant: D65 (for classic daylight evaluations) or Illuminant A / C for specific haze testing according to ASTM D1003.
Standard Observer: 2° for strict color analysis or 10° for large-scale visual correspondence.
Measurement Mode: Quality Control Mode (QC Mode) for direct comparison of standard and sample with target tolerances.
Color Spaces: Activate CIE Lab, XYZ, and Yxy to capture both haze factors and absolute color coordinates simultaneously.

The Professional Workflow: 6 Steps to Error-Free Measurements

Power On and Warm-up: Start the device and allow a warm-up phase of approximately 15–20 minutes. The integrated temperature sensor monitors system stability.
Perform Dual-Calibration: Meticulously execute black and white calibration using the provided transmission and reflection standards. This eliminates thermal drifts.
Prepare the Sample Chamber: Choose the appropriate sample holder (e.g., the micro-aperture holder for small quantities) and clean the chamber of any residue.
Define the Standard: Place your reference sample (or select a digitally stored standard profile) and complete the reference measurement.
Start Sample Measurement: Secure the test sample (film, glass plate, or cuvette) absolutely flat and vibration-free in the chamber. Trigger the measurement via the 7-inch touchscreen.
Data Export & QC Check: Verify the data metrics (Haze, WI, YI, Gardner, etc.) on the display and transfer the records via USB or Bluetooth to the SQCX quality management software for archiving.

Troubleshooting Deviations and Errors

1. Unstable or Highly Fluctuating Measurement Values Corrective Actions: Check if external light sources are shining directly into the transmission chamber. Ensure that the sample does not shift or vibrate during the measuring process. Carefully clean the sensor area with compressed air.

2. Calibration Fails (Error Message on Touchscreen) Corrective Actions: Inspect the white calibration tile for dirt, dust, or yellowing. Clean the tile exclusively with specialized cleaner and an optical cloth. Make sure the tile sits perfectly flush against the aperture.

3. Systematically High Haze / Turbidity Values Corrective Actions: Check the sample for surface smudges, grease films, or dust particles. If measuring liquids, check the cuvette for tiny air bubbles on the inside walls (gently tap the cuvette before inserting).

4. Data Transfer to Software Disconnects Corrective Actions: Swap the USB data cable for a shielded laboratory-grade cable or restart the Bluetooth pairing. Check the device manager to verify that the 3nh SQCX software drivers are up to date.

Maintenance & Care for Maximum Lifespan

Regular care secures the measurement precision of the YS6002 over years of operation. Observe these core rules:

Dust Protection: Always cover the measurement chamber when not in use to prevent dust accumulation inside the 154 mm integrating sphere.
Tile Preservation: Store calibration standards in a dark, dry, and dust-protected environment inside their original case. Never touch the active measuring surface.
Climate Stability: Operate the benchtop unit in a climate-controlled laboratory environment away from direct sunlight, drafts, and radiators.
Gentle Touchscreen Use: Use only clean fingertips or a dedicated stylus on the capacitive 7-inch TFT display – never sharp laboratory tools.
Recertification: Send the instrument for factory recalibration at regular intervals according to your ISO quality standards to ensure data traceability.

Frequently Asked Questions from Lab Practice (FAQ)

Question 1: Can the YS6002 measure both liquid and solid samples?

Answer: Yes. Thanks to its advanced d/0 transmissive geometry, solid materials like plastic plates and films, as well as liquids in standard cuvettes, can be precisely analyzed.

Question 2: What is the difference between the Pt-Co and Gardner indices?

Answer: The Pt-Co index (Apha value) is used for nearly clear, slightly yellowish liquids (e.g., water, solvents). The Gardner index covers darker yellow and brown tones (e.g., oils, resins). The YS6002 supports both indices natively.

Question 3: How often should calibration be performed?

Answer: As a general rule: At least once per shift or every 4 to 8 hours. If the laboratory experiences significant temperature changes, calibration should be repeated immediately.

Question 4: Does the device support measurement according to ASTM D1003?

Answer: Yes, the YS6002 fully complies with ASTM D1003/1044 requirements for evaluating haze and total transmission.

Question 5: Is the software included in the scope of delivery?

Answer: Yes, the professional quality management software SQCX is available for download, enabling extensive data analysis and report generation on a PC.

Conclusion

The 3nh YS6002 benchtop color and haze meter sets benchmarks for accuracy and user comfort. By combining grating spectroscopy with a standard-compliant d/0 geometry, laboratories eliminate uncertainties when evaluating transparent or opaque products. By maintaining the optimized workflow and regular maintenance cycles, the system delivers uncompromised, high-precision measurement results for the most demanding quality standards over years of service.
