Product Description

portable Grinder / Polisher

E-FM-MP1 = META-POL-P = Power Operated.

E-FM-MP2 = META-POL-B = Battery Operated.


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

META-POL’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.

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 system, power plants, and so on.  Field Metallography allows for quick on-site evaluation of a component. There are numerous advantages in using on site field metallography.

Portable and can be used on-site.
•Can be used to monitor 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 area

Product Advantages

  • A portable unit for electrolytic polishing and etching
  • Fully automatic program run controlled by a microprocessor
  • Independent from the power supply by using a Li-Ion storage battery
  • Handle with the integrated polishing unit, Start / Stop function
  • Handle with multicolor LED for showing the current operating state
  • Operating panel with clear LCD display for all important operating state
  • Adjustable voltage and current, adjustable operating time

After grinding and polishing (instead of chemical etching) electrolytic etching of the prepared spot may be
used with connecting the Etching Pen.

---Connect the Etching Pen to Socket #4.
---Clamp the anode (red wire) of the Etching Pen to the sample or workpiece by the clamp or the magnetic anode supplied.
---Select the Etching Mode (E1 or E2) from the adjustment knob #3
---Remove the closing cap and insert a cotton-wool tampon into the Etching Pen.
---Fill the Etching Pen with the relevant electrolyte (depending on material) using the syringe by putting the syringe into the filling hole on the side of the etching pen.
---The cotton-wool tampon is soaked with the relevant electrolyte.
---Wipe the etching pen on the prepared spot until etching is done. (The mirror-like polished surface becomes darker).
---After the etching process is finished, clean the area with water or alcohol (ethanol) to stop the etching process.
---Do not over etch when using the portable microscope. Forgetting a replica for laboratory examination make over-etching.
---When not in use the close the cap of the Etching Pen.
