Entris II Advanced (BCA) Precision Balance
The Sartorius Entris II Advanced (BCA) precision balances weigh from 220 g up to 12,200 g with 1 mg, 10 mg or 100 mg readability and a typical stabilization time of 1.0 second or less. A graphic touch display, real-time level support, integrated protection systems, CalAuditTrail and 13 built-in applications add value to the Entris II range; "i" models also offer isoCAL internal adjustment.
Overview
The Sartorius Entris II Advanced (BCA) Precision Balances are best-value laboratory balances for everyday precision weighing, with extra features that simplify daily work and documentation. Models with internal adjustment are marked i (for example BCA623i-1S); the others are adjusted with an external test weight.
1 mg models with draft shield (Ø 120 mm pan)
BCA223 (220 g), BCA323 (320 g), BCA423 (420 g) and BCA623 (620 g), each with internal (i) and external adjustment, and BCA1203i (1,200 g) with internal adjustment.
10 mg models with open pan (182 × 182 mm pan)
BCA822 (820 g), BCA1202 (1,200 g), BCA2202 (2,200 g), BCA3202 (3,200 g), BCA4202 (4,200 g) and BCA6202 (6,200 g), each with internal (i) and external adjustment.
100 mg models with open pan (182 × 182 mm pan)
BCA2201 (2,200 g), BCA5201 (5,200 g), BCA8201 (8,200 g), BCA10201 (10,200 g) and BCA12201 (12,200 g), each with internal (i) and external adjustment.
What the Advanced line adds
Real-time level support: an internal electronic level sensor monitors the level continuously, raises an alarm if it is not correct and guides you interactively through levelling.
Integrated protection systems: three configurable levels decide which weighing data is valid, so only valid data is passed to external devices.
CalAuditTrail: calibration processes are documented automatically with the calibration trigger and a date and time stamp.
Graphic touch display: an intuitive graphic touch display and user management control access to the balance settings.
Quality built in and easy to connect
A monolithic weigh cell, a fast stabilization time and parts made of hard-wearing PBT, stainless steel and glass give accurate, durable results that are easy to clean. The balance detects Sartorius accessories such as a printer or a second display automatically, and a USB Type-C interface, a 9-pin RS232 interface and the PC-Direct feature transfer weighing data straight into spreadsheets or documents. Thirteen built-in application programs and 13 languages are included. Our team can help you choose the right model and accessories.
