Features

Adopt new super monolithic sensor technology - accurate, fast, stable and reliable.

♦ Sensitivity: unparalleled sensor design and processing technology ensure the sensitivity of micro-weighting results

♦ Precision: Particular super monolithic sensor technology ensures the accuracy, stability and consistency of weighing results.

♦ High-Speed: The sensor technology of horizontal bar, combined with excellent circuit design and software algorithm, meets the requirements of rapid weighing in the laboratory Compliance with 21CFR Part 11 - full traceability

♦ Designed in accordance with FDA data integrity principles to achieve attributable, legible, contemporaneous, original, and accurate data (ALCOA).

♦ User administration: Three-level user administration through access control

♦ Electronic Signature: The user''s electronic signature can be used to sign the final report of the weighing operation.

♦ Audit Trail and Weighing Log: An audit trail is a tamper-proof electronic log file with a timestamp that allows the reconstruction of events related to the creation, modification, and/or deletion of records.

♦ Data transmission security; Electronic records should be protected from any tampering.

♦ Data output meets GLP/GMP requirements Operating system with full touch screen

♦ Operation requirement is concise and clear, so customers can conveniently operate the balance and directly read the results on the screen to have a wonderful experience. At the same time, it is necessary to consider the special requirements of users in special industries, such as non-contact operation, etc. Adopt automatic calibration and adjustment technology

♦ isoCAL automatic internal calibration and adjustment function, automatically triggered by temperature and time, fully ensure the accuracy of weighing results. Adopt automatic door technology (optional)

♦ The technology of automatically opening and closing door is not only to improve customer experience satisfaction, but also necessary to consider the requirements of non-contact weighing in special industries, so as to achieve the goal of not contacting the balance during the weighing operation. Besides, The balance has a function of memorizing door position. Fully automatic electrostatic removal technology (optional)

♦ Built-in ionizer can automatically eliminate the effect of static electricity on weighing Built-in multi-applications

♦ Built-in multi-applications, print output, & data output meet GLP/GMP requirements Standard communication interface

♦ Automatically identify the printer

♦ Standard RS232, easy to connect with peripherals

♦ PC connection function not only is easy to connect to PC, but also can directly transfer weighing data to spreadsheets (Excel) Standard USB-C interface for data storage and export functions
