Sparklike Handheld 3.0 is the backbone of measuring IGU’s with double glazing. Just place the device against the unit, press the button and receive an instant result with high accuracy.
Sparklike Handheld™ has become the industry standard for non-destructive inert gas measurement for insulating glass units.
Trusted worldwide: Used by IG manufacturers, window/door producers, and testing labs
Optional Krypton measurement: Expand capabilities to Krypton fill verification
Proven methodology for determining gas concentration in sealed insulating glass units: Plasma emission spectroscopy (ASTM E2649-20, ift Rosenheim) ensures repeatable results
Simple workflow: Place the device on the IGU, press the button, receive instant concentration in 2 seconds
The Sparklike Handheld 3.0™ has been independently tested and validated by ift Rosenheim, confirming its compliance with the EN 1279-3 standard for gas concentration measurement accuracy.
The device is primarily designed for use in factories or laboratories, supporting quality control at different stages of the production process.
Sparklike does not recommend using the Handheld™ device in the field, as direct sunlight can interfere with measurement accuracy. However, it has been successfully used in some cases for measuring installed windows. As a rule of thumb, accurate results depend on knowing the glass structure being measured.
Sparklike Handheld™ can measure certain coated and laminated insulating glass units, but there are limitations based on glass type and structure.
Low-E coatings:
Yes, the device can measure double-glazed IG units that have one Low-E coating, provided the other pane is clear glass. The measurement must always be taken through the clear side, as Low-E coatings reflect the light emission used in spark technology.
Laminated glass:
Sparklike Handheld™ can measure through thin laminated glass under specific conditions:
Typically 1 or 2 interlayers of 0.38 mm each (e.g., 3+3 mm or 4+4 mm glass)
Higher gas fill rates improve spark penetration
Measure close to the spacer for best accuracy
The spark must be visible during measurement
Laminated units with multiple interlayers or excessive thickness may not produce reliable results.
For IGUs with multiple coatings, complex laminations, or triple glazing, Sparklike recommends using a Sparklike Laser device, which can measure through coatings and laminations using laser (TDLAS) technology.
The result is displayed in about two seconds, enabling fast checks even in high-volume production.
The Sparklike Handheld™ measures argon as standard and can be configured to measure krypton at the time of manufacturing.
It is important to note that the gas type cannot be changed later as the measurement configuration is defined during production. Therefore, customers should confirm their preferred gas type when ordering the device.
Thanks to its small size, it is easy to get a fast reading of gas concentration. The user can simply place the device against the unit, press the button and receive an instant result with high accuracy.
