Equipment used for the testing of gas, oil, LPG, NGL and other chemicals used in the industrial process.  Instruments and equipment used for analysis of petroleum, glycol, amine and other hydrocarboPetroleum testing equipment is essential for ensuring the quality, safety, and performance of petroleum products. Commonly used equipment includes digital density meters for measuring density and specific gravity, viscometers for assessing viscosity, and Pensky-Martens closed cup testers for determining flash points. X-ray fluorescence (XRF) spectrometers are used to measure sulfur content, while distillation apparatuses help determine boiling range characteristics. Karl Fischer titrators are employed to measure water content, and potentiometric titrators are used for determining the total acid number (TAN). Micro carbon residue testers measure carbon residue, and octane engines assess the anti-knock properties of gasoline. Additionally, fluorescent indicator adsorption apparatuses are used to measure aromatic content. Each piece of equipment plays a crucial role in maintaining the standards and regulatory compliance of petroleum products.
