Biobase Electronic Precision Analytical Balance, 500G Capacity, 1Mg Readability, External Calibration

Model: BP5003B | Capacity: 500 g | Readability: 1 mg | External Calibration

The Biobase BP5003B is a high-precision electronic analytical balance designed for accurate weighing in research laboratories, pharmaceutical quality control, academic institutions, and industrial environments. Built around a next-generation electromagnetic weighing sensor, this model provides stable and repeatable measurements with a readability of 1 mg, making it ideal for routine analytical and precision weighing applications.

Its fully enclosed five-side transparent windshield minimizes the effects of air currents and environmental disturbances, ensuring consistent results even in sensitive laboratory environments. The balance combines high measuring accuracy with durability, intuitive operation, and multiple built-in functions to support a wide range of laboratory tasks.

Design and Construction

The BP5003B features a modern, humanized design with a full glass draft shield for enhanced visibility and protection against airflow interference. The rugged internal structure and electromagnetic weighing sensor ensure long-term stability and reliable performance, even with frequent use.

A large LCD display provides clear and easy-to-read measurements, improving operator comfort and reducing errors during prolonged working sessions. The solid build and compact footprint make it suitable for most laboratory benches without occupying excessive space.

Key Functional Capabilities

This analytical balance supports multiple intelligent functions for convenient and flexible operation, including:

• Automatic counting for piece counting applications
• Unit conversion (grams, carats, gold ounces, and other metric units)
• Full-range tare and zero memory functions
• Stability indication for consistent measurement results
• Built-in self-check and automatic fault detection
• Four-point linear calibration to maintain accuracy across the weighing range
• Overload protection system to prevent sensor damage

The integrated RS232 communication interface allows direct connection to external devices such as computers, printers, and data acquisition systems for seamless data transfer and documentation.

Additionally, the balance includes a bottom weighing (density determination) hook, enabling suspended weighing for density measurements and specialized applications.
