Introduction
The Elcometer 280 is a 'handle type' EDM Detector designed to make pulsed DC high Voltage EDM testing safer, more convenient and more reliable than ever before.
The Elcometer 280 utilises specialist electronics to inspect coatings without the need to connect ground wires to the component substrate – ideal for inspecting large surfaces and pipes.
The Elcometer 280 utilises high Voltage pulsed DC technology to inspect coating porosity – even if the coating is wet, dirty or slightly conductive.
The Elcometer 280 sets the standard for the safety of high Voltage detection – a two-stage safety switch, a bright LED display and on-screen icon display when high Voltage start-up, and an extended coil thread to protect the user from sparks.
A variety of probe accessories can be used to inspect the porosity/pinhole of coatings up to 25 mm thick.
Rugged, shockproof and waterproof design, even in harsh environments.
Features
When a hole is detected, the display will flash, the LED indicator will be on, the alarm will sound, and the volume will be adjustable.
0.5-35kV range (user selectable) to inspect coating porosity up to 25mm (1") thick
The safety switch in the handle cuts off the power supply as soon as it is released
The rugged, shockproof and waterproof design ensures a long service life – even in harsh environments
The balanced design is ergonomic and comes with a shoulder strap that lasts for a long time
A wide range of interchangeable probe accessories are available – compatible with all Elcometer models of Elcometer Flash Leak Detectors
Ideal for inspecting clean, wet, dirty, or slightly conductive coatings
Based on the coating thickness value, the Voltage calculator automatically sets the correct Voltage (Advanced only)
The internal Voltage verification device ensures that the selected Voltage is the test Voltage
Structural advantages

☆ Glue hanging auxiliary handle:This allows for better control and balance during the inspection process.
☆ Large waterproof keys:It's easy to use – it doesn't hurt to wear gloves.
☆ High Voltage on/off:Separate buttons minimise the risk of accidental start-up.
☆ Clear backlit LCD display:Even in the dark, all relevant information is displayed.
☆ Shoulder strap holes:Quickly clip on the shoulder strap.
☆ Special extended coil threads:Designed to meet EN61010 standards, the threads provide additional protection for user use.
☆ Integrated safety trigger switch:If released, turn off the high Voltage.
☆ Ground feedback wire socket:1/4 circle lock/unlock function to ensure that it does not fall off during use.
☆ Easy to remove the battery pack:Fully charged in 4 hours, it can last up to more than 30 hours.
