    • LCD liquid crystal display
    LCD display screen is clear and bright, with a reasonable layout, making it convenient for users to read the weighing results
    • Transparent glass draft shield
    The transparent glass draft shield makes the samples visible in multiple directions during the weighing process, and can also be disassembled and cleaned to achieve quick cleaning.
    • Toggle between different units
    Units such as grams (g), carats (Ct), and ounces (oz) can be freely switched.
    • Various weighing modes
    Basic weighing, percentage weighing, counting weighing, check weighing.
    • Optimized product structure design
    The entire machine adopts a streamlined design，with enhanced design strength, anti-leakage, anti-static, anti-corrosion characteristics.
    • Built-in RS232 two-way communication interface
    Can realize the connection between the balance and the computer and micro-printer. The weighing results can also be transferred to other open applications in a PC.
