Introduction
A petroleum density tester is an instrument used to measure the density and the specific gravity of the petroleum products, such as the crude oils, the fuels, and the lubricants, and it is used in the petroleum, the petrochemical, the fuel, and the quality control industries. The density is the mass per unit volume of the material, and it is an important parameter for the assessment of the quality and the composition of the petroleum products, and the petroleum density tester measures the density by the hydrometer method, the pycnometer method, or the digital density meter, following the standard test methods, such as the ASTM and the ISO standards; the petroleum density tester consists of a density measurement system, a temperature control system, and the accessories, and it provides the density or the specific gravity at the reference temperature, with features such as the digital display and the temperature compensation; the petroleum density tester is used for the measurement of the density of the crude oil, the fuels, the lubricants, and the other products, for the quality control, for the assessment of the composition, for the conversion of the volumes, and for many other applications, and it is an essential instrument for the petroleum testing. Petroleum density testers are used in the petroleum industry, in the petrochemical industry, in the fuel industry, in the laboratories, and for many other applications. With their density measurement, petroleum density testers are essential for the product quality control.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The petroleum density tester is used in petroleum refineries, fuel terminals, pipeline custody transfer stations and third-party testing organizations to measure the density of crude oil, gasoline, diesel, fuel oil, lubricants and other petroleum products. It supports crude oil valuation, product specification compliance, custody transfer measurement, refinery process control and inventory management. Density is a fundamental physical property used to calculate volume-to-mass conversion, determine API gravity for crude oil classification, verify product consistency and calculate blending ratios. Accurate density measurement is essential for commercial transactions involving petroleum products, as small density differences can significantly affect the calculated mass and value of large shipments.
Q2: What standards does the instrument comply with?
A: The hydrometer method follows ASTM D1298 for density by hydrometer, ISO 3675 for crude oil density, and the corresponding GB/T 1884 method. Digital density meters reference ASTM D4052 and ISO 12185. The instrument complies with relevant laboratory safety standards. Test temperature should follow the standard specification, typically 15 degrees Celsius or 20 degrees Celsius.
Q3: What is the warranty period for the whole machine and key components?
A: The bath and controller are covered by a 12-month warranty. Hydrometers, cylinders and thermometers are consumables excluded from warranty. Digital density sensors may have a separate warranty as specified. Damage from improper sample handling or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with density measurement and temperature correction. We provide an operation manual and remote guidance. Proper sample temperature equilibration, hydrometer reading technique and temperature correction are important for accurate results.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Bath temperature calibration against a reference thermometer is recommended every 6-12 months. Hydrometers should be verified periodically with certified density standards. Digital density meters require calibration with reference fluids per the manufacturer schedule. Full method verification is recommended for accredited laboratories.
Q7: Are supporting consumables universal?
A: Hydrometers, cylinders and thermometers are available from laboratory suppliers, though accuracy class should match the standard method. Long-term consumable cost is low for hydrometer systems; digital sensors may require periodic servicing.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement method, bath capacity, temperature range and hydrometer set. Additional accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the instrument and accessories with an operation manual. Remote commissioning guidance is provided. On-site service is not included for standard orders.
Q10: What types of samples are compatible with this equipment?
A: The tester handles petroleum products within the method density and viscosity range. Samples should be homogeneous and free of trapped air bubbles. Highly volatile samples require careful handling to prevent light end loss. Waxy or viscous samples may require heating to ensure flowability. Users should follow the standard method for sample handling, test temperature and density correction to the reference temperature.
