I. Main Features of the HSY-6900B Fully Automatic Potentiometric Titrator

1. Hybrid Synchronous Liquid Feeding System: Internationally advanced simultaneous 4-channel injection, supporting expansion up to 8-channel modular combination liquid feeding system. Titrants, additives, or auxiliary reagents can be combined arbitrarily, completely eliminating manual operations for complex liquid addition requirements.

2. Built-in Burette: The world's safest built-in burette, integrated within the instrument. The burette can be observed externally through a viewing window, ensuring complete separation between the solution and personnel during operation to avoid spills and operator injury.

3. Optional Capacity Burettes: 5ML/10ML/25ML.

4. Cloud Service Function (Optional): The first to adopt the cloud service concept domestically. The instrument is equipped with a network interface, allowing data to be stored in the cloud via the internet. It supports big data applications in experimental modes, moving beyond the era of standalone instrument operation.

5. Diversified Titration Platforms: Freely choose between an independent titration station or 16-position (Type A), 20-position (Type B), 34-position (Type C), or 40-position (Type D) automatic samplers. These samplers enable fully automated multitasking operations, eliminating worries about multi-batch and multi-task operations. The entire process requires no manual monitoring, improving work efficiency.
