Shimadzu Model BL220H High-Precision Electronic Balance
Overview and Affordability
The Shimadzu Model BL220H is part of the BL Series of high-precision electronic balances, known for making high resolution affordable. This digital top-loading balance is an excellent choice for general laboratory applications and scientific investigation, providing precision results for routine weighing tasks. The unit employs a high-precision electromagnetic system that is remarkably compact, comparable in size to a portable scale.
Performance and Stability
The BL220H is engineered for speed and reliability, featuring a very quick response time. This fast response significantly enhances efficiency, especially during repeated weighing work. The instrument operates with high stability, providing steady readings even when working under poor environmental conditions. The standard deviation (repeatability) is highly precise.
Functionality and Operation
Designed for ease of use, the BL220H is equipped with a square pan. The instrument provides several standard functions accessible via simple key-touch operation:
• Various Unit Conversions: Switching between different weighing units is straightforward.
• Percentage Mode: This function is included as standard.
• Analog Bar Display: This feature allows the user to see the remaining weighing capacity at a glance, proving especially helpful when filling containers directly on the balance.
• Piece Counting: The piece counting function allows the user to read the quantity of parts immediately upon placing them on the pan. Precision can be enhanced for smaller parts by setting the key after loading 20, 50, or 100 pieces, beyond the standard ten pieces. Switching between piece counting and gram display is achieved with a single key press.
Connectivity and Design
The balance features an LCD display with a backlight. Standard accessories include a protective in-use cover and a simple windbreak (brown smoke color). For generating reports, the optional EP-60A Electronic Printer can be connected directly to the balance without requiring a special interface. An optional interface (IFB-102A RS-232C Interface) is also available to enable communication with a PC.
