Features

Essential functions for semi-micro weighing in an easy-to-adopt balance

0.01 mg readability for up to 101 g (BM-255DS) with the smart range function^*1

AD-Just – Automatic self-sensitivity adjustment using the internal weight

Anti-static glass breeze break with a transparent evaporated metal coating

Two breeze break rings, including a high-profile one for better draft protection

Internal repeatability test to quickly assess the performance at the installation location

Selectable response characteristics (FAST/MID/SLOW) to suit drafts and vibrations at the location

User access control (UAC) with password lock and user rights management for up to 10 users

Key lock function for operation via PC commands only

GLP/GMP/GCP/ISO compliant output to meet documentation requirements

Clock and calendar function

Data memory function

Universal Flex Coms (UFC) to customize printout content and layout^*2

Gross/Net/Tare output

Counting mode with the Automatic Counting Accuracy Improvement (ACAI) function

Percent mode function for target weighing or checking sample variation

Density measurement mode

Underhook for weighing a magnetic material as well as measuring density

Multiple units of measure: g, mg, oz, ozt, ct, mom, dwt, gr, density (either tael or tola can be added upon request)

Clearly visible, reverse-backlit LCD

Auto power ON and OFF functions

RS-232C and USB (Type-C) interfaces as standard

Optional BM-014 pipette accuracy testing kit

*1 Smart range function: The full precision range becomes available again after a re-zero or tare operation.
*2 For editing and sending UFC setting commands, download WinCT-UFC here

External Input/Output

RS-232C interface
Quick/bi-directional USB interface^*3
External key input (jack socket)

*3 Users can toggle between the Quick USB mode (plug-and-play with weighing data output to a PC only) and the Virtual COM mode (for bi-directional communication) using internal settings. For the latter, a driver (available for download here) needs to be installed on the PC (except for those with Windows 10/11).
