BD-T18609-ZG5 Automatic acid value tester

Applicable standards

GB/T_7304-2014, GB/T 18609

Main Features

1. BD-T18609-ZG5 Automatic acid value tester consists of three parts: hardware circuit, titration device and PC. With the support of application software, it can measure the acid value of petroleum products.
2. it has a simple structure, beautiful appearance, high degree of automation and accurate analysis results. It is an ideal intelligent instrument for petrochemical laboratories, analysis rooms and scientific research departments.
3. Universal Windows operating system, the operation adopts human-computer dialogue mode, which is simple and easy to understand.
4. The titration device adopts precision transmission device, which has stable and reliable performance and low transmission noise.
5. Automatic cleaning, automatic replenishing, fixed-value adding, and mechanical and electrical functions are organically combined.
6. Multi-parameter settings and corrections make the analysis of different types of samples easier and faster, with shorter analysis time and more accurate results.
7. The end point is automatically judged, and the end point can be manually selected to delete/add. The titration results can be saved as WORD documents, and the titration data can be saved as EXCEL documents. The titration results can be stored and printed, and complete titration data can be provided for analysis and research.
8. The electrode signal adopts high-impedance input, and the electrode potential is more stable and reliable.
9. Glass electrode: pencil shape, length 125-180mm, diameter 8-14mm, universal for 0≤pH≤14; reference electrode: saturated calomel electrode or silver/silver chloride electrode; motor-driven burette: capable of equal amounts of dripping, accurate is ±0.001ml; in non-aqueous titration of acids and bases, the dripping rate is lower than 0.2ml/min, and the dripping rate near the end point is 0.05ml/min.
