The Handheld NOVA enables the non-destructive measurement of argon concentration in double-glazed insulating glass units. Measurements are performed directly through the insulating glass unit—without gas extraction and without damaging the sealed unit. Optional krypton measurement is available.

Its lightweight, battery-operated design makes the Handheld NOVA ideal for production quality control. Within seconds, the instrument delivers reproducible measurement results and supports complete documentation of gas filling quality.

The Handheld NOVA uses Plasma Emission Spectroscopy (PES). A high-voltage spark is generated inside the cavity of the insulating glass unit, producing a light emission that is analysed to determine the argon concentration.

• Fully automatic, non-destructive verification of insulating gas concentration
• Integration into existing insulating glass production lines
• Inspection of every insulating glass unit produced
• Continuous monitoring and optimisation of gas filling processes
• Automatic documentation and traceability
• Reduced inspection effort
• Turnkey installation available
• Measurement without manual intervention

The Laser Integrated enables fully automatic, non-destructive verification of insulating gas concentration directly within the insulating glass production line. Designed for double- and triple-glazed insulating glass units, including coated and laminated units, the system continuously verifies gas fill quality without interrupting the production process.

Fully integrated into the production line, the Laser Integrated automatically inspects every insulating glass unit produced. Measurement data is recorded automatically, providing complete traceability, reliable quality assurance and continuous optimisation of the gas filling process.

The Laser Integrated uses TDLAS (Tunable Diode Laser Absorption Spectroscopy) to automatically determine the residual oxygen concentration within the cavity. Based on this measurement, the system calculates the insulating gas concentration without damaging the insulating glass unit. Operating directly within the production line, it delivers accurate, highly reproducible results for continuous verification of gas fill quality.
