Due to the unique method of operation, the Elcometer 236 minimises the risk of additional damage to a coating and avoids the dangerous act of coating popping off the surface which can occur with some high Voltage techniques.

Convenient carriage system
The Elcometer 236 DC Holiday Detector is supplied as a complete kit, allowing the user to immediately (upon charging the unit) begin testing.
  • The kit is supplied in a hard backed transit case for trasportation and long term storage.
