Automatic Acid Tester
The FDR-2271 Automatic Acid Tester from Changsha Friend Experimental Analysis Instrument Co., Ltd is a potentiometric titration system designed for measuring acid and base numbers in petroleum products, lubricants, and related substances. It complies with SH/T 0251 and GB/T 7304 standards, using perchloric acid potentiometric titration to determine endpoints automatically. The instrument features a computer-controlled interface with Chinese-language software, supporting mouse and keyboard operation for user-friendly interaction.
This tester supports multiple titration modes, including pre-titration, default end titration, blank titration, and manual titration, allowing customisation for different experimental requirements. It is constructed with corrosion-resistant materials to handle various titration reactions, including acid-base, redox, precipitation, complexometric, and non-aqueous titrations. The system also includes automatic cleaning, rehydration, and liquid addition functions, reducing manual intervention and improving repeatability.
Primary applications include quality control in petroleum refining, lubricant manufacturing, and chemical analysis laboratories. The tester’s ability to display potential curves (E-V), first derivative curves (dE/dV), electrode potential (E), and titration volume (V) provides comprehensive data for analytical purposes. Buyers in these sectors should confirm compatibility with their specific sample types and required standards before procurement.

Sourcing Automatic Acid Tester from Changsha Friend Experimental Analysis Instrument Co., Ltd - China Import Guide
Before purchasing, confirm that the FDR-2271 meets the specific standards and methods required for your laboratory’s testing protocols. Request documentation or certification proving compliance with SH/T 0251 and GB/T 7304, as well as any additional industry-specific standards your facility adheres to. Verify whether the supplier offers calibration services or validation support to ensure the instrument meets your accuracy requirements.
Discuss logistics in detail, as laboratory instruments like this often require careful handling to avoid damage during transit. Confirm the Incoterms (e.g., FOB, CIF) and whether the supplier provides export-standard packaging, including shock-absorbing materials and moisture barriers. Lead times for custom configurations or additional accessories should be clarified, as these may extend delivery schedules.
Upon receipt, conduct a full functionality test, including a calibration check using certified reference materials. Inspect the electrodes and titration system for any signs of damage or corrosion. Ensure that the supplied documentation, including user manuals and certificates, is comprehensive and translated into your preferred language to facilitate proper installation, operation, and maintenance.
