Sparklike Handheld™

Fast and easy gas measurement for double-glazed IGUs

For double glazed insulating glass units

Sparklike Handheld™ – Non-destructive insulating gas measurement device

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.

  • Non-destructive: Measure argon without breaking the IGU
  • Fast results: Measurement in ~2 seconds
  • Portable: Battery-operated and lightweight for factory or on-site use
  • Accurate: Approved by ASTM E2649-20 and is independently validated by ift Rosenheim (The requirements of EN 1279-3 are fulfilled)

Industry standard for non-destructive argon measurement

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

Validated by ift Rosenheim – Precision You Can Trust

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.

  • Average deviation of just ±1.0% compared to gas chromatography.
  • Sparklike Handheld 3.0™ demonstrates exceptional reliability for measuring argon levels in double-glazed insulating glass units.

Frequently Asked Questions

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.
