Elcometer 266 DC Holiday Detector

The Elcometer 266 revolutionises high voltage DC testing of coatings porosity detection making it safer, easier and more reliable than ever before. 

The Elcometer 266 holiday detector can be used to test porosity on coatings up to 7.5mm (300 mils) thick and is ideal for inspecting coatings on pipelines and other protective coatings. This holiday tester features a built-in voltage calculator which will determine and set the correct test voltage based upon the test standard and the thickness of coating being tested.

Elcometer 266 DC Holiday Detector Features

 

  • Voltage calculator automatically sets the correct voltage from your coating thickness value
  • Adjustable Voltage:
    • 0.5kV - 1kV in 50V steps
    • 1kV to 30kV in 100V steps
  • Dual safety switch on handle to avoid accidental switch on (Grey/orange probe handles only)
  • Internal Voltmeter/ Jeep tester ensures that the test voltage equals the selected voltage
  • Visual and audible alarms, Bright LEDs on the handle, as well as a loud buzzer, clearly indicate when a holiday is detected
  • To change maximum voltage range, select a different handle; 5kV, 15kV or 30kV DC or 30kV DC continuous
  • A wide range of probe brushes and rolling springs available

 

Elcometer 266 DC Holiday Detector Features Explained

 

High Voltage DC Testing
Voltage calculator

Automatically sets the correct voltage from your coating thickness value. No need to use look up tables. Enter the test standard and the coating thickness and the gauge will automatically programme the correct voltage.

 
Electrical Tester
Adjustable Voltage

No need for screwdriver: 0.5kV - 1kV in 50V steps, 1kV to 30kV in 100V steps. Sensitivity to current can be manually preset or automatically adjusted by the gauge for partially conductive coatings.

 
Voltage Detector
Internal Voltmeter/ Jeep tester

Ensures that the test voltage equals the selected voltage. The closed loop system ensures that the generated test voltage is accurately measured and continuously controlled, regardless of climatic conditions.

 
Electric Current Tester
Interchangeable probe handles

Available, 5kV, 15kV and 30kV DC and DC continuous versions.

 
Porosity Testing
Audible and visual alarms

Visual and audible alarms are activated when a flaw is detected. Bright LEDs on the handle, as well as a loud audible alarm, clearly indicate if the gauge is on (Red) and when a spark is detected (Blue).

 
Continuity Tester Accessory
Battery pack

Can be recharged inside or outside the gauge for continued use. Batteries are fully charged within 4 hours and provide up to 40 hours continuous use between charges.

 
Holiday Tester Accessory
Universal probe adaptors

Enables the Elcometer 266 to work with all major holiday detector accessories.

 
DC Holiday Detector

Screen display

Large, backlit display enables easy viewing even in dark environments. When a flaw is detected the backlight also flashes.

 
Electric Current Tester
Second hand grip

The optional second hand grip is designed for two handed use without compromising its safety. Ideal for testing pipes and tank floors.

 

Elcometer 266 DC Holiday Detector Safety Features

 

  • Dual safety switch on handle to avoid accidental switch on. 2-stage safety switch ensures that if the Elcometer 266 handle is not gripped, the handle will switch off.
  • Specialised ribbing provides superior protection while an optional second hand grip is ideal for two handed use. This holiday detector has been specifically designed to meet standard EN61010.
  • The speaker on the gauge clearly emits a ticking noise to indicate that there is voltage at the handle.
  • A loud audible alarm is activated when a spark is detected. The beep volume can also be adjusted to ensure it can be heard - even in noisy environments.

An Introduction to Pinholes and Holidays – Porosity Detection

Corrosion is caused by two things – a steel substrate and oxygen, while contaminants such as water can accelerate the process. The coating is there to protect the steel from oxygen and contaminants. A flaw in the coating can leave the substrate poorly protected, or in some cases completely exposed.

The high voltage method comes in two versions – Continuous DC and Pulsed DC. In this video, we’ll be introducing you to the Continuous DC method, which is used to test non-conductive coatings up to 7.5mm (300mils) thick on conductive substrates.

Testing Coating Porosity using an Elcometer Continuous DC High Voltage Holiday Detector

Setting the correct voltage is vital, as testing with a voltage that is too low could fail to break down the gap between the probe and substrate, missing flaws. While testing with a voltage that’s too high could break down and damage the coating, causing the unit to alarm when there are no flaws, while creating a flaw in the process. Testing with bright blue sparks is a clear sign the voltage is too high, and is probably damaging the coating.
