Standard Configuration
Stainless steel chamber, two aluminium-alloy heated shelves with independent temperature control and mechanical temperature limits, observation door, touchscreen controller, parameter memory, USB and RS-485 interfaces. Standard data management includes PDF/CSV export, assigned operator permissions and timestamped event audit records. Protection covers leakage current, overtemperature, vacuum timeout and sensor alarms. No regulatory certification or compliance claim is implied.
Optional Accessories
Vacuum pump and pump sound enclosure are optional. Remote monitoring or messaging services require a separately confirmed option and availability; they are not standard. Confirm pump compatibility, tubing, gas-pressure reference and final configuration.
