The increasing regulatory requirements in the energy sector necessitate precise color measurement. Industry reports show that over 87% of quality control laboratories now utilize standardized colorimetric testing. As noted in the Journal of Petroleum Science and Engineering, "Color measurement provides the first line of defense against product contamination and degradation" (Totten et al., 2021). The PS-SD01 Oil Color Tester meets this demand with its advanced optical calibration system and standardized color reference library.

"The precision of modern colorimetric testers like the PS-SD01 has transformed lubricant quality control. Their ability to detect subtle color variations correlates with critical parameters including oxidation levels and contaminant presence."

Technical Comparison with Alternative Methods

Analysis Time Comparison

Operational Cost Analysis

Conventional color grading methods such as visual comparison and basic photometric instruments suffer from subjective interpretation and limited precision. As documented in the International Journal of Analytical Chemistry, instrumental analysis reduces measurement variance by 63% compared to traditional methods. The PS-SD01 Oil Color Tester establishes standardization through its calibrated optical path and digital result interpretation.

Industry Validation: Independent testing by the Petroleum Analytical Standards Consortium confirmed 99.2% correlation between PS-SD01 results and reference spectrophotometers costing 8-10x more.

Expert Technical FAQ

Q1: What optical calibration standards does the PS-SD01 comply with?

The PS-SD01 Oil Color Tester is calibrated to SH/T 0168-92 standards and certified against NIST-traceable color references. The instrument employs matched optical filters corresponding to the 16-color scale defined in GB/T 6540.

Q2: What is the required sample volume for accurate measurement?

Optimal results are achieved with 15ml samples in the provided colorimetric tubes. The instrument requires a minimum optical path of 10mm through the sample.

Q3: How frequently should calibration be performed?

Initial calibration verification should occur monthly under normal laboratory conditions, or after every 500 tests. The instrument features automated calibration verification diagnostics.

Q4: Can the PS-SD01 measure opaque or highly viscous oils?

For opaque samples, a dilution protocol using kerosene (specified in ASTM D1500) is required. Viscous samples should be pre-heated to 60°C ±5°C to ensure proper flow characteristics.

Q5: What environmental conditions affect measurement accuracy?

Ambient light intensity above 1000 lux may introduce interference. The instrument operates within specifications at 15-35°C and 20-80% relative humidity.

Q6: What maintenance procedures are required?

Quarterly cleaning of the optical chamber with spectroscopic-grade ethanol is recommended. Sample tubes should be cleaned immediately after each test using petroleum ether.

Q7: How does this instrument correlate with ASTM D1500 color scale?

The 16-color gradations directly correspond to ASTM D1500 0.5-8.0 scale. Cross-certification documents are available from Baoding Push for quality audit purposes.
