Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›The Automatic Tan And TBN Tester For Oil from Changsha Friend Experimental Analysis Instrument Co., Ltd is a computer-controlled potentiometric titration system designed for determining the base number of petroleum products in compliance with SH/T 0251 and GB/T 7304 standards. It features a Windows-based interface with mouse and keyboard input, enabling real-time display of potential curves, first derivative curves, electrode potential, titration volume and results. The system automatically identifies titration endpoints and calculates results, supporting pre-titration, preset endpoint titration, blank titration, and manual titration modes alongside custom experimental setups.
Constructed with corrosion-resistant materials, the tester accommodates a broad selection of titration reactions, including acid-base, redox, precipitation, and non-aqueous titrations when paired with appropriate electrodes. Its technical specifications include a measuring range of 0.00 to 14.00 pH, -1800 to 1800.0 mV, and -5.0 to 105.0 °C, with resolutions of 0.01 pH, 0.1 mV, and 0.1 °C respectively. The burette system offers capacities of 10 ml or 20 ml, with tolerances of ±0.025 ml and ±0.035 ml, and resolutions of 1/10000 and 2/10000 respectively, ensuring precise titration control.
This tester is primarily used in petroleum and lubricant quality control laboratories, research institutions, and industrial testing facilities where accurate measurement of total base number and acidity is critical. Buyers typically include oil refineries, additive manufacturers, and independent testing labs that require reliable, automated titration for compliance and quality assurance. The instrument’s ability to handle complex titrations and its automatic cleaning and dosing features make it suitable for high-throughput environments.
