AKF-3B Bromine Valence Bromine Index Tester

In the vast and precise industrial system of petrochemicals, the inherent "health" and "activity" of every drop of oil directly affect production efficiency, product lifespan, and ultimate benefits. Bromine value and bromine index, as the core indicators for measuring the content of unsaturated hydrocarbons in oil products, are the key "listening instruments" for insight into this inherent characteristic. It warns of the risk of oil oxidation stability and monitors the conversion efficiency of key processes such as alkylation, serving as a scientific link between production control and quality safety.

Faced with this high standard detection demand, relying on traditional methods often comes with the problems of cumbersome operation, low efficiency, and human error. Nowadays, the AKF-3B, meticulously crafted by Shanghai Hegong Scientific Instrument Co., Ltd. (hereinafter referred to as "Hegong Scientific Instrument")Bromine Value Bromine Index TesterWith its excellent precision, intelligent and convenient experience, and reliable service that exceeds expectations, it has become a trusted domestic preferred solution for many petrochemical, quality inspection and R&D laboratories, helping enterprises to elevate quality control to a new dimension.

AKF-3BBromine Value Bromine Index TesterDefine industry level precision and efficiency

AKF-3B is a newly developed electrochemical analysis instrument by Shanghai Hegong Scientific Instrument Co., Ltd. It adopts the principle of microcoulometry titration. The sample is directly added to the titration cell, and bromine is produced through electrolysis, which reacts with unsaturated substances in the sample. After the reaction is completed, the instrument automatically maintains equilibrium. The instrument can automatically calculate the bromine value and bromine index content in the sample based on the amount of electricity consumed to produce bromine. Widely used for the determination of bromine value and bromine index of petroleum and chemical products such as gasoline, kerosene, diesel, lubricating oil, and light and heavy aromatic hydrocarbons.

AKF-3B embodies multiple thoughtful technological innovations in its design:

More stable endpoint determination: The use of potential method to indicate the endpoint ensures higher repeatability and accuracy compared to traditional methods, resulting in a more stable signal.

Safer operating environment: Supports the use of benzene free electrolytes, significantly reducing the health hazards of traditional reagents to operators and environmental pollution, reflecting the people-oriented design concept.

Faster detection speed: relying on intelligent program control and multiple adjustable electrolysis speeds, the instrument can automatically determine the endpoint. Usually, it only takes about 1 minute to complete the determination of a single sample, greatly improving the laboratory's detection throughput.

More extensive compliance: The instrument design is fully compatible with domestic and foreign standard methods such as SH/T0630, GB/T11136, ASTMD1492, ensuring comparability and recognition of test data within the range.

Its core performance parameters are a direct proof of its powerful capabilities:

Parameter project technical indicators

Measurement range: Bromine valence: 0-300gBr/100g; Bromine index: 1-1000mgBr/100g

Resolution 0.01mgBr

Accuracy ± 3% (± 0.3mgBr when bromine index<1mgBr/100g)

Detection limit of 0.1mgBr

Color LCD touch screen for operation interface

Empirical evidence: When precision technology meets strict standards

The persuasiveness of data is worth a thousand words. The following two actual test cases visually demonstrate the reliability of AKF-3B in practical applications:

1. Verification of accuracy of reference materials

Continuous testing was conducted using bromine index standard substance (nominal value of 1942mgBr/100g), and the results are shown in the table below. All test deviations were far better than the qualified requirement of ≤ 3%, demonstrating the excellent accuracy of the instrument.

2. Verification of repeatability of actual oil products

Three parallel measurements were conducted on a certain petroleum sample, and the results were highly concentrated

More than just sales: we promise to provide "beyond expectations" full cycle services

We are well aware that half of the value of an instrument lies in its factory performance, and the other half comes from long-term and stable service guarantee. Hegongke Instrument has proposed a "beyond expected after-sales service system" in the industry and has made a firm commitment to the quality of its own products with confidence.

Wuyou Buyqi: We implement nationwide unified real price sales with transparent prices. More importantly, since 2013, we have dared to provide customers with the "30 day no reason return and exchange" benefit. Any dissatisfaction can result in a return, as we firmly believe that good products speak for themselves.

Full process escort: Starting from on-site installation and debugging, free on-site operation training, to 7 * 24-hour technical response, regular patrol services, and long-term free application technical support, we have built a complete service network.

Continuous win-win situation: We also offer the rights of exchanging old products for new ones and long-term free software upgrades for our entire range of products, aiming to establish a long-term and trustworthy partnership with customers and grow together with them.

Choose Hegong Scientific Instrument, choose a reliable commitment

In today's pursuit of high-quality development and independent and controllable supply chain, choosing an excellent domestically produced scientific instrument is not only a consideration of cost-effectiveness, but also a vote for a company's technological background, quality philosophy, and service original intention.

The equipment of Shanghai Hegong Scientific Instrument Co., Ltd. is not only an intelligent device that can accurately understand the "health" password of oil products, but also the crystallization of Hegong Scientific Instrument's dual core driving concept of "research and development+service". It carries our ideal of breaking the inherent concept of "imported instruments are better", and also fulfills our commitment to providing customers with "one-stop" solutions.
