Introduction
A petroleum air release value tester is an instrument used to measure the air release property of the lubricating oils and the hydraulic fluids, which indicates the ability of the oil to release the entrained air, and it is used in the petroleum, the lubricant, the hydraulic, and the quality control industries. The air release value is the time required for the air entrained in the oil to be released under the specified conditions, and it is measured by the aeration of the oil sample at a specified temperature, followed by the measurement of the time for the air content to decrease to a specified level, following the standard test methods, such as the ASTM standards; the petroleum air release value tester consists of a test vessel, an aeration system, a temperature control system, a density or the air content measurement system, and the controls, and it provides the air release value, with features such as the temperature control and the data display; the petroleum air release value tester is used for the testing of the air release properties of the turbine oils, the hydraulic fluids, and the lubricating oils, for the quality control, for the product development, and for many other applications, and it is an essential instrument for the oil testing. Petroleum air release value testers are used in the petroleum industry, in the lubricant industry, in the hydraulic industry, in the laboratories, and for many other applications. With their air release measurement, petroleum air release value testers are essential for the oil quality control.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The petroleum air release value tester is used in petroleum refineries, lubricant laboratories and third-party testing organizations to measure the air release properties of lubricating oils, particularly hydraulic oils and turbine oils. It supports lubricant formulation evaluation, product specification compliance, quality control and research on oil aeration behavior. The air release value indicates how quickly entrained air separates from the oil, which is critical for hydraulic system performance, cavitation prevention and maintaining effective lubrication in high-speed machinery where air entrainment can cause pump damage, spongy operation and reduced system efficiency.
Q2: What standards does the instrument comply with?
A: The test method follows ISO 9120 for determination of air release value of fire-resistant hydraulic fluids, ASTM D3427 for air release properties of petroleum oils, and the corresponding GB/T method. The instrument hardware complies with relevant laboratory electrical and pressure safety standards. Test temperature and air pressure should follow the standard specification.
Q3: What is the warranty period for the whole machine and key components?
A: The whole tester is covered by a 12-month warranty. The heating system, timer, air flow controller and bath are covered, while glassware, seals and tubing are consumables excluded from warranty. Damage from improper air pressure, glassware breakage or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with the test method and oil sample handling. We provide an operation manual and remote guidance. Proper sample preparation, temperature equilibration and air flow control are important for accurate and repeatable 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: Temperature calibration against a reference thermometer is recommended every 6-12 months. Air flow and pressure should be verified periodically with a calibrated gauge. Timer accuracy can be checked annually. Full system verification with a reference oil is recommended for accredited laboratories.
Q7: Are supporting consumables universal?
A: Glassware, seals and tubing are available from laboratory suppliers, though original glassware dimensions should match the standard method. Compressed air or nitrogen supply should meet the method purity and pressure requirements. Long-term consumable cost is moderate.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes test temperature, bath capacity and automation level. Additional glassware sets and spare parts 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, glassware and accessories with an operation manual. Remote commissioning guidance is provided. On-site installation and training are not included for standard orders but can be arranged for laboratory setup projects.
Q10: What types of samples are compatible with this equipment?
A: The tester handles lubricating oils and hydraulic fluids within the method viscosity and temperature range. Highly viscous oils may require longer equilibration time. Samples containing water, particulates or additives that affect foaming may produce inconsistent results and should be pretreated or noted in the report. Users should follow the standard method for sample handling and test conditions.
