NM01D266--4U

The USED Elcometer 266 Holiday Detector, accompanied by a Probe Handle rated for 15 Kv, is a portable instrument utilized for the non-destructive detection of discontinuities, such as pinholes and holidays, in non-conductive protective coatings applied over conductive substrates. Being offered in USED condition, this unit presents a potentially cost-effective solution for ensuring coating integrity.

The Elcometer 266 operates by applying a controlled electrical voltage to the surface of the coating. At any point where the non-conductive layer is breached, allowing contact with the underlying conductive material, an electrical circuit is completed, triggering an audible and/or visual alarm. This method is crucial for quality control in various industries to prevent corrosion and ensure the long-term performance of protective coatings on structures like pipelines, tanks, and other critical assets.  

The inclusion of a Probe Handle with a 15 Kv rating indicates the maximum voltage output capability of this specific configuration. This voltage capacity suggests its suitability for inspecting coatings of moderate thickness. The Elcometer 266 platform is known for its versatility in testing a wide array of coating types applied to conductive materials such as steel and concrete.  

Typical features expected from an Elcometer 266 Holiday Detector include:

• Selectable Testing Modes (Potential Variation in Used Units): Depending on the original model specifications, the Elcometer 266 may offer both Direct Current (DC) and Alternating Current (AC) testing modes. DC is generally preferred for thicker coatings, providing higher sensitivity for detecting through-thickness flaws. AC is often employed for thinner coatings and can be more effective in the presence of surface contamination or moisture. The specific testing modes available on this particular USED unit would require verification.

• Adjustable Output Voltage: The instrument typically allows for the adjustment of the output voltage to match the specific requirements of the coating thickness, material, and relevant inspection standards. The 15 Kv rated probe handle confirms the unit can operate within a range up to this maximum voltage.  

• Compatibility with Various Probes and Electrodes (Included Accessories May Vary): The Elcometer 266 is designed to be used with a selection of probes and electrodes tailored to different surface geometries and inspection areas. These can include rolling spring probes for large, flat surfaces, conductive rubber electrodes for curved surfaces like pipes and tanks, and brush probes for intricate details and hard-to-reach areas. The specific probe(s) or electrode(s) included with this USED unit are not specified and would need to be confirmed.

• Adjustable Sensitivity: A sensitivity control feature allows the operator to fine-tune the detection threshold, minimizing the occurrence of false alarms due to minor variations or imperfections in the coating that may not constitute a critical flaw.

• Clear Alarm Indication: Upon detection of a holiday, the instrument typically provides both an audible signal (such as a beep or tone) and a visual indicator (like a flashing LED) to immediately alert the inspector.  

• Portable and Durable Design: Constructed for use in field environments, the Elcometer 266 is generally designed to be lightweight and housed in a robust casing to withstand the demands of on-site inspections.

• Battery Operation: The unit is typically powered by rechargeable batteries, offering portability and freedom of movement during inspections. The condition and charge-holding capacity of the batteries in this USED unit should be assessed.  

Prospective buyers of this USED Elcometer 266 Holiday Detector should carefully consider the following:

• Verification of the specific model and its original functionalities (DC/AC capabilities).

• Confirmation of the type and condition of any probes or electrodes included with the unit.

• Assessment of the instrument's operational status, including the accuracy of the voltage output and the functionality of the alarm systems.

• Evaluation of the condition and expected lifespan of the internal batteries.

• Inquiry about any available calibration records or service history for the unit.
