Sparklike Handheld 3.0

Verified accuracy for gas concentration measurement in insulating glass units

A recent evaluation by ift Rosenheim has validated the performance of the Sparklike Handheld 3.0™ for measuring gas concentration in insulating glass units (IGUs). The results confirm that the device meets the accuracy requirements of EN 1279-3, providing reliable and non-destructive measurements.

Non-destructive testing through plasma emission spectroscopy
The Sparklike Handheld 3.0 utilizes plasma emission spectroscopy to measure argon gas concentration within IGUs. By creating a high-voltage spark in the glass cavity, the device analyses the resulting light spectrum to determine the gas concentration. This method eliminates the need for invasive procedures, preserving the integrity of the glass unit during testing.

Comprehensive testing by ift Rosenheim
To evaluate its performance, the Sparklike Handheld 3.0 underwent a series of tests under varied conditions:

  • Measurements from both inner and outer sides of IGUs.
  • Assessment across different coatings and glass thicknesses.
  • Performance through laminated glass layers.
  • Testing with freshly filled IGUs containing 92.5% argon gas.

These tests simulated real-world manufacturing and operational scenarios, providing a clear picture of the device’s practical applications.

Key findings

  1. Accuracy and consistency
    The device showed an average deviation of 1% from reference gas chromatography (GC) measurements, with a standard deviation of 0.8%. These results indicate its capability for precise and repeatable measurements.
  2. Broad application range
    The device performed reliably across various IGU configurations, including laminated glass and uncoated float glass. However, measurements on low-emissivity, electrically conductive coatings are limited to one side only.
  3. Standards compliance
    The Sparklike Handheld 3.0 fulfills the accuracy requirements of EN 1279-3, confirming its suitability for quality control in IGU production.

Supporting efficient quality control
The ability to measure argon concentration non-destructively is a practical solution for manufacturers and quality assurance professionals. It reduces testing time and minimizes material waste while ensuring that IGUs meet regulatory and performance standards.
