Sparklike has unveiled the Handheld NOVA™, a next-generation device for non-destructive measurement of insulating gases in double-glazed insulating glass units (IGUs). Building on Sparklike’s established spark emission spectroscopy technology, the NOVA combines a redesigned industrial structure with a modern software environment and improved data handling to meet the demands of today’s glass production and quality control.

Argon and krypton gas concentrations are critical for thermal performance and long-term product quality, yet they are invisible during production. Variations in gas fill across shifts, operators, and production conditions can lead to warranty issues, inefficiencies, and reputational risks if detected only after units reach the market. The Handheld NOVA™ enables manufacturers to verify gas fill non-destructively, allowing tested units to remain fully functional and ready for delivery.

The device delivers measurements in roughly two seconds and offers single and multisample modes, user-configurable PASS/FAIL limits, and optional QR code support for unit-level traceability. Wireless data transfer and browser-based access facilitate integration into quality monitoring systems. Argon measurement is standard, with krypton available as an optional feature.

Designed specifically for double-glazed units, the NOVA can measure units with one low-e coating when tested through the clear pane. Certain thin laminated structures are measurable under defined conditions, while more complex configurations, such as triple glazing or multiple coatings, are addressed by Sparklike’s Laser Portable™ and Laser Integrated™ solutions.

Weighing approximately 1.7 kg, the portable, battery-operated NOVA features an ergonomic design for daily factory use. Its non-destructive measurement method eliminates the need to break sealed units, making gas verification a practical part of routine production rather than an occasional check.
