Automatic Mercaptan Sulfur Content Tester
This Automatic Mercaptan Sulfur Content Tester is designed and manufactured to the People’s Republic of China national standard GB/T 1792, specifically for measuring mercaptan sulfur in distillate fuels such as jet fuel, gasoline, kerosene and light diesel within a 0.0003 to 0.01% (m/m) range. The instrument excludes hydrogen sulfide interference, ensuring accurate potentiometric titration results for fuel quality control. It features an LCD with an English operation interface, displaying test parameters and measurement outcomes in real time.
The system supports multiple titration modes, including pre-titration, preset endpoint titration, blank titration and manual titration, with the ability to create custom modes based on user preferences. It accommodates various electrode types for acid-base, redox, precipitation and complexometric titrations, as well as non-aqueous titration and pH measurement. The stirring system uses PWM modulation for software-controlled speed and low noise, while the perchloric acid titration system is built with anti-corrosive materials to handle diverse titration tasks.
This tester is primarily used in petroleum refineries, fuel testing laboratories and quality control facilities where precise sulfur content analysis is critical for compliance and performance. Buyers typically include oil producers, fuel distributors and independent testing labs. The instrument’s compact dimensions of 340 × 400 × 400 mm and 10 kg weight make it suitable for bench-top use in controlled environments. Confirm MOQ, packaging and lead time directly with the supplier.

Sourcing Automatic Mercaptan Sulfur Content Tester from Changsha Friend Experimental Analysis Instrument Co., Ltd - China Import Guide
Before ordering, verify the tester’s compliance with your required standards, such as GB/T 1792 or ASTM D3227, and confirm whether the supplier can provide calibration certificates or validation reports for the instrument. Ask for documentation proving traceability to national metrology institutes, as this is often a requirement for laboratory accreditation.
Confirm the Incoterms, such as FOB or CIF, and the port of loading in China, as this will affect shipping costs and responsibility for insurance. Lead times for analytical instruments can vary, so request a realistic production and delivery schedule. Payment terms, such as TT (Telegraphic Transfer) or L/C (Letter of Credit), should also be clarified to align with your procurement policies.
For quality assurance, inspect the instrument upon arrival to ensure it matches the specifications, including the measurement ranges, resolution and stability values. Request a factory acceptance test (FAT) report if available, and consider a third-party inspection for high-value orders. Check that the supplier includes a user manual, calibration tools and spare electrodes, as these are essential for immediate operation.
