Détecteur de fuite géomembrane KODIN-7DJ
Instrument portatif d'essai d'étincelles pour localiser les défauts des revêtements géomembranes électriquement isolants lors de l'installation et de la maintenance.
Product Overview
The KODIN-7DJ Geomembrane Leak Detector is a portable high-voltage spark-test instrument for locating pinholes, punctures and other discontinuities in electrically insulating geomembrane liners. It is intended for installation acceptance, repair checks and routine maintenance on HDPE, LDPE, PVC, polypropylene and asphalt geomembranes.
Key Features
- No pre-buried wire required: connect the ground lead to the conductive sub-base below the liner.
- Wide theoretical test range: suitable for insulating liners from 0.1 to 35 mm, subject to site conductivity and voltage settings.
- Audio-visual indication: a detected discontinuity triggers a clear alarm for field localization.
- Automatic leak counter: records up to 999 alarm events for inspection tracking.
- Field battery: 12.6 V, 4400 mAh lithium battery for mobile site work.
- Adjustable operation: output voltage and sensitivity can be matched to the liner and site conditions.

Field Preparation
- Confirm that the liner is electrically insulating and the substrate can provide a conductive return path.
- Clean the membrane surface and remove standing water, metal debris and exposed conductive materials.
- Install the ground rod and connect the ground lead securely.
- Run a comparison test on a known defect and adjust voltage and sensitivity before formal inspection.
- Mark and record each confirmed leak point for repair and retesting.
Frequently Asked Questions
Which liner materials can be tested?
Electrically insulating HDPE, LDPE, PVC, polypropylene and asphalt geomembranes are supported. Conductive liners are not compatible with the spark-test principle.
Is a pre-buried wire required?
No. A ground rod is placed into the conductive sub-base and connected to the instrument before testing.
What can cause false alarms?
Standing water, a wet surface, exposed conductive substrate, metal debris or an excessively high voltage setting can trigger false indications.
Is a site comparison test necessary?
Yes. Effective detection depends on liner thickness, substrate conductivity and the chosen output voltage, so a known test defect should be checked first.
