The latest evaluation by ift Rosenheim confirms that the Sparklike Laser Portable 2.2™ meets the accuracy requirements of EN 1279-3 for measuring gas concentrations in insulating glass units (IGUs). With its tunable diode laser absorption spectroscopy (TDLAS) technology, the device provides non-invasive, precise measurements across various configurations of double and triple glazing.
Innovative Technology for Accurate Measurements
The Sparklike Laser Portable 2.2 is based on TDLAS technology, which uses a vertical-cavity surface-emitting laser (VCSEL) to measure oxygen levels and calculate argon or krypton concentrations. This approach allows for measurements through coatings and laminated glass without damaging the IGU or requiring additional components inside.
Key features of the device include:
- Scanning of IGU dimensions to ensure precise measurement points.
- Measurement through uncoated, coated, and laminated glass.
- Application in both double- and triple-glazed units.
This versatility makes the Sparklike Laser Portable 2.2 a valuable tool for quality control in the production of insulating glass.
