XE305S Series Semimicro Analytical/Precision Balance Tester
Features
unparalleled sensor design and processing technology, to ensure the sensitivity of trace weighing results
precision: unique super single sensor technology, ensure the accuracy of trace weighing results, the stability and consistency
fast: adopt the single lever sensor technology, combined with excellent circuit design and software algorithm, and meet the requirement of laboratory of weighing fast
design according to the American FDA data integrity principle, implement the data accurate, clear, easy to read, synchronization, original and traceability (end)
user management: through access control for user level 3 management.
electronic signature: electronic signature can be used to sign the final report of the weighing process.
audit tracking and weighing log: audit tracking is a time-stamped tamper-proof electronic log files, allows reconstruction and record to create, modify, delete the related events.
data transmission security: electronic records should be protected, to avoid being tampered with.
data output in line with the requirements of GLP/GMP
operational requirements is concise, clear, satisfy the user’s convenience, visual display good experience, at the same time, considering the special requirements of special industry users, such as non-contact operation at any time, any temperature can obtain accurate weighing results.
IsoCAL (the internal calibration and adjustment function, fully ensure accurate weighing results, using automatic temperature and time control of calibration and adjustment function.
Automatic identification of standard communication interface, and a printer
standard RS232, easy connection and peripherals.
