HKL-664 Automated Potentiometric Titrator
Overview
HKL-664 Automated Potentiometric Titrator conforms to ASTM D664 Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration. The sample is dissolved in a titration solvent and titrated potentiometrically with alcoholic potassium hydroxide using a glass indicating electrode and a reference electrode or a combination electrode. The meter readings are plotted manually or automatically against the respective volumes of titrating solution and the end points are taken only at well-defined inflections in the resulting curve. When no definite inflections are obtained and for used oils, end points are taken at meter readings corresponding to those found for aqueous acidic and basic buffer solutions.
Features
Strictly complies with ASTM D664 standard. The instrument features a compact and practical overall design.
The device uses a flat heating mantle, which enables rapid and stable heating. Temperature regulation is achieved indirectly through a voltage regulation module.
The instrument adopts a basket-type structure, is operated from the front panel, has a simple structure, and is easy to maintain.

FAQ
Q1: What standards does this product (HKL-664 Automated Potentiometric Titrator) comply with?
A: HKL-664 Automated Potentiometric Titrator conforms to ASTM D664 Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration. This test method covers procedures for the determination of acidic constituents in petroleum products, lubricants, biodiesel, and blends of biodiesel.
Q2: Significance and use of HKL-664 Automated Potentiometric Titrator?
A: New and used petroleum products, biodiesel, and blends of biodiesel may contain acidic constituents that are present as additives or as degradation products formed during service, such as oxidation products. The relative amount of these materials can be determined by titrating with bases. The acid number is a measure of this amount of acidic substance in the oil, always under the conditions of the test. The acid number is used as a guide in the quality control of lubricating oil formulations. It is also sometimes used as a measure of lubricant degradation in service. Any condemning limits must be empirically established. Since a variety of oxidation products contribute to the acid number and the organic acids vary widely in corrosion properties, the test method cannot be used to predict corrosive-ness of oil or biodiesel and blends under service conditions. No general correlation is known between acid number and the corrosive tendency of biodiesel and blends or oils toward metals.
Q3: What types of instruments does your company mainly provide?
A: Hello! We diversified our expertise into life science analysis, environmental monitoring, and industrial automation control.
