MOBIPREP Portable Grinding/Polishing & Electrolytic Etching Machine

In-situ/Field metallography is widely used for microstructure analysis on large parts (samples) that cannot be easily carried or where destructive preparation is not permissible such as storage tanks, piping systems, power plants, etc. In-situ Metallography allows for quick on-site evaluation of a component. There are numerous advantages to using in-situ/field metallography.

MOBIPREP is a battery-powered portable Grinder / Polisher and etcher designed for metallographic sample preparation in the field or in the laboratory. MOBIPREP contains maintenance-free batteries to work without stationary mains and consists of a control unit and a precision hand-guided grinding-polishing device with a high-performance micromotor.

MOBIPREP’s hand-guided device can be used with either 45° or 90° angle or straight grinding-polishing pieces. The switch for ON/OFF is on the hand guide and provides a click sensation with a confirmation tone from the control unit when the switch is operated.

All accessories are supplied with hard case protection and a carrying bag where you have sufficient space to place your consumables. With the etching pen, MOBIPREP may be used for electrolytic etching. Thus working in the field with alloyed steels is possible which can be etched by weak electrolytes instead of strong acids.

•Portable and can be used on-site.
•Can be used to monitor the quality of purchased components.
•Nondestructive with Replica techniques.
•Replicas are ideal for both flat and curved surfaces.
•Ability to evaluate microstructural changes in a component during its lifetime.
•Wide range of application areas.
