Core Testing Equipment

▸Our in-house quality control laboratory is equipped with state-of-the-art testing instruments to ensure accurate and reliable measurement of all critical parameters:

• Laser Particle Size Analyzer (ISO 13320) – ensures precise particle size distribution for stable gradation in cement slurry systems.

• XRF Spectrometer – provides accurate elemental analysis (SiO₂, Al₂O₃, Fe₂O₃, CaO) to verify raw material and finished product consistency.

• Digital Density Analyzer – complies with ISO 787-10 for precise bulk density and true density measurement, meeting oilfield cement specifications.

• Moisture Analyzer – uses thermogravimetric analysis for accurate moisture content determination (≤0.3%), preventing negative impact on slurry performance.
