Built-in PC and Control Software
With built-in touch panel PC and control software instant temperature and pressure monitoring with automatic detection of pressure drop with data exporting options.
Automatic pressure monitoring
Automatic analysis with precise pressure detection and pressure drop control
Precise temperature control
Embedded AI temperature control technology gives the 0.001°C bath temperature stability.
Precise time detection
Automatic elapsed time detection to save time for the operator
Data memory and transfer
Internal memory keeps the calibration and settings data with the latest 100 measurement results. Oxidation results can be transferred to a PC aor USB environment at any time.
Rapid Cooling
Fast cooling with coil connected to the around test chamber to eliminate time loss from 150°C to ambient.
Safety Locks
Interlocks for over temperature and over pressure guarantees safe analysis. In case of any issue, visual and audible notifications warns the user with instructions to follow.
