Since 2000, spark emission spectroscopy has been the foundation of Sparklike technology. The goal has always been simple: make the invisible gas inside insulating glass units measurable without damaging the unit.
Unlike scratches, sealant issues, or spacer alignment problems, argon and krypton cannot be seen. But proper gas fill is important for thermal performance and meeting industry requirements. That is why reliable gas measurement has always been important in insulating glass production.
The beginning of Non-Destructive Measurement
The challenge was finding a way to measure invisible gas without breaking the product.
The first Sparklike systems were stationary and connected to external power. The non-destructive measurement technology already existed, but portability was limited. The core principle was the same as today: a high-voltage spark is created inside the insulating glass cavity, and the light emission is analysed to determine gas concentration.
2006: The first handheld device
In 2006, Sparklike introduced its first true handheld device. For the first time, gas fill levels could be checked directly on the production floor using a portable device.
Measurement became easier to include in daily production routines while the insulating glass unit remained fully usable.
2008–2022: Improving a proven tool
In 2008, Handheld 2.0 improved durability and reliability even further. Many of these devices are still calibrated and serviced today.
In 2022, Sparklike launched Handheld 3.0 with a renewed design and improved usability. The proven spark technology and fast 2-second measurement time remained the same. By this stage, the device had become a trusted standard for non-destructive gas measurement in insulating glass quality control.
The need for better connectivity
Production environments were changing. Manufacturers increasingly needed traceability, documentation, wireless data transfer, and integration with quality systems.
Small software updates were no longer enough.
Handheld NOVA™
Handheld NOVA™ is the first fully redesigned generation of the device. The proven spark emission spectroscopy technology remains unchanged, but everything around it has been modernised.
NOVA™ introduces a redesigned industrial structure, new software environment, wireless data transfer, QR-code-based traceability, and improved measurement modes.
The evolution from stationary systems to NOVA™ reflects how gas measurement itself has changed from simple verification to connected quality control.
For over two decades, Sparklike has built its solutions around a stable and proven technology trusted by more than 1,000 customers worldwide. The invisible gas inside insulating glass units still cannot be seen, but today it can be measured, documented, and integrated into production more easily than ever before.
