Import Air Release Value Analyzer — Buy in wholesale FOB from Supplier in China

The Air Release Value Analyzer from Changsha Friend Experimental Analysis Instrument Co., Ltd is a laboratory instrument designed to determine the air release value of fuel oil, hydraulic oil, turbine oil and other petroleum products, in accordance with standard test methods for measuring the time required for entrained air to escape from lubricating oils. The unit combines a heat-resistant jacketed test tube, circulating water bath, air heating bath, gas pressure control and gas time control within a single integrated housing. Water bath temperature spans ambient to 100 degrees Celsius with control accuracy of plus or minus 1 degree, while the air heating section operates up to 90 degrees Celsius with plus or minus 5 degrees accuracy. Power requirement is 220 volts plus or minus 10 percent at 50 hertz, with maximum power consumption of 1000 volt-amperes.

The instrument employs an LCD screen with English display interface and menu-prompted input for operator guidance. A computerised temperature control system maintains the stated precision, and the integrated regulator device ensures steady air flow through the test assembly. The jacketed tube construction provides thermal insulation for the test fluid during the air release measurement cycle. Standard test methodology for this product category typically follows ASTM D3427 or IP 313 protocols, where a sample is heated to test temperature, air is blown through and the time for density to return to baseline is recorded. Typical sample volumes range from 200 to 300 millilitres depending on test standard applied.

This analyser serves petroleum testing laboratories, oil blending facilities, quality control departments in refineries, and research institutions evaluating lubricant performance. Hydraulic oil users in aviation, power generation and heavy machinery sectors require documented air release values to prevent compressibility failures in high-speed systems. Importers should confirm whether the unit ships with standard glassware and tubing sets, and verify compatibility with local voltage standards. The supplier lists a Hunan province address and holds harbor-level trust status, though response rate data is not available.

Changsha Friend Experimental Analysis Instrument Co., Ltd is located at 3F/8, No. 627 Lugu Road, Longsea Group, Changsha, Hunan Province, 410000, China. The company operates from a registered commercial address in Changsha's technology district, with the building name indicating a multi-tenant business complex rather than a dedicated manufacturing campus. The supplier holds harbor-level trust tier status on the platform, which represents a baseline verification level. Response rate is recorded at 0.00 percent with zero average response hours, indicating either a new listing or inactive inquiry management at time of data collection.

The supplier's product range centres on petroleum testing instrumentation, specifically the air release value analyser described here. No employee count, annual revenue, factory size, or client reference information is present in the source data. The company name structure, combining a city reference with 'Experimental Analysis Instrument,' suggests specialisation in laboratory equipment rather than broad industrial supply. Buyers should verify current production capacity, whether the unit is manufactured in-house or sourced from an OEM partner, and the availability of English-language technical support before placing orders.
