Description

This is the original factory Service Manual for the BT3500 Random Access Chemistry Analyzer, published by Biotecnica Instruments S.p.A. (Italy).
It is intended strictly for authorized and trained service personnel and provides complete mechanical, electronic, software, and diagnostic coverage of the BT3500 system.

The BT3500 is a fully automated clinical chemistry and electrolyte analyzer capable of 300–500 tests per hour, supporting serum and urine analysis, with integrated photometer and ISE (Ion Selective Electrode) modules.

This manual is a true service-level document — not an operator or user guide.
