Integrated printer
The integrated printer in the VARIOKLAV Type 65 TC steam sterilizer logs all
process on its printout pursuant to DIN EN 285 (February 1997). The printout is
tamper-proof. In this way, data on each sterilization process are reliably stored for
future reference. The log header is printed out as soon as the program is started.
Two chamber temperatures (control and monitoring) and the chamber pressure are
continuously monitored during program execution and printed upon termination of
the program. In the printout, values are logged every minute during the sterilizing
phase and every 3 minutes during the heating and cooling phases.
Errors occuring during sterilization are printed immediately.
