 The premature corrosion of a substrate is often due to the failure of it's coating. Major causes of failure are flaws in the finished coating, these include pinholes, holidays, inclusions, thin spots and bubbles.
The Elcometer 236's convenient carrying case allows the probe handle and accessories to be attached to the front making the Elcometer 236 ideal for field, site or laboratory inspection.
An accessory pouch, which accommodates the additional rechargeable battery (optional) can also be attached to the soft carrying case - thereby extending inspection time without the need for recharging the unit.

- Simple to use
- Robust and fully portable
- Audio and visual alarms - for noisy environments
- Supplied with a band brush probe
- For full set of probe accessories click here
- Digital display of output voltage and current

The Elcometer 236 is available in two versions: 1 - 15kV and 2 - 30kV.
Each unit provides the User with complete control of voltage and sensitivity settings. Due to the 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 systems.
 Convenient Kit Case
The Elcometer 236 DC Holiday Detector is supplied as a complete kit, allowing the User to begin testing immediately after charging the unit.
The kit is supplied in a hard backed transit case for transportation and long term storage.
| Elcometer 236 High Voltage Holiday Detectior
The High Voltage Detection Technique locates flaws in insulating coatings on conductive substrates. A power supply within the instrument generates a high DC Voltage which is supplied to a suitable probe. An earth voltage return lead from the instrument is connected to an uncoated area of the metal of the test substrate.
As the probe is passed over the coated surface, a flaw is indicated by a spark at the contact point with an audible alarm in the detector and a visual alarm in the probe handle.
Note: This test uses the principle of an electric current conducting through a material. When a spark occurs, the circuit is closed and the alarm sounds indicating a flaw. Varying the DC Voltage varies the distance a spark will "jump" to the metal substrate. The maximum distance a spark will jump is dependant on the dialectric strength of free air.
The High Voltage Technique can be used to locate flaws in coatings on concrete. As most concrete conducts electricity (due to moisure inherent in concrete), the Elcometer 236 can be used. |

EXTERNAL DIAMETER PIPE TESTING KIT
The Elcometer External Diameter Pipe Testing Kit has been created specifically to allow the pipeline inspector to create probes for non standard pipe sizes.
Each kit allows the user to create either 1 external spring for use on a 635mm (25") diameter pipe, or up to 3 springs of User defined diameters.
Larger diameters can be made by connecting additional spring lengths together.
Spring lengths can be purchased separately using the part numbers listed above. |
