Base Unit with AC Adapter and 9V Battery (No plates included)

Krell Technologies Part No.: PRTX

  • $ 3,543.00 or

Proton FTTX Field Polisher is designed for field polishing environments in which cable and connector access is limited. Rather than bringing a cable to the polisher, Proton can be located in close proximity of the connector to be processed.

Proton features true, hand-held operation in a rugged and battery operated package. Applications include FTTx, CATV and avionic/harsh environments.

Production performance is now available in field environments in the form of Proton. Though portable and battery operated, Proton consistently achieves singlemode UPC and APC finishes.

Proton incorporates the same Independent Suspension (IS) and optically aligned workholder design found in Krell's mass production Scepter Polishing System.
