Solutions to Eliminate the Greatest Enemy of Precision Weighing
| Features | ||
 Instant and smooth static elimination using a built-in fanless ionizer to ensure stable weighing Large working space for better operability and a wider range of applications Interlockable sliding doors allowing efficient operation with both hands Anti-static glass breeze break with a thin evaporated metal coating Adjustable (manual or automatic) response characteristics to help cope with the effect of drafts and vibrations Automatic self calibration to maintain accuracy under temperature changes Embedded temperature, humidity and atmospheric pressure sensors Multiple weighing units: g, mg, oz, ozt, ct, mom, dwt, grain, specific gravity (either tael or tola can be added upon request) Comes equipped with the handy AD-1688 weighing data logger Clearly visible, reverse-backlit LCD GLP/GMP/GCP/ISO compliant output Clock and calendar function Data memory function RS-232C and Quick USB interfaces as standard Counting mode with the Automatic Counting Accuracy Improvement (ACAI) function Percent mode function Comparator function with buzzer Auto power on function Underhook function Special pans/holder (BM-20/22) Density determination function and an optional density determination kit (for BM-252/200/300/500 only) Optional pipette accuracy testing kit Windows Communication Tools software (WinCT) Expert assessment of the set-up environment using AND-MEET* (please inquire at your local distributor for details) |
