Sparklike Laser devices offer a precise, non-invasive solution for measuring insulating gas concentrations in Insulating Glass Units (IGUs). By using Tunable Diode Laser Spectroscopy (TDLAS), the devices ensure accuracy without compromising the unit’s structure, making them a trusted tool in quality assurance processes.
How the Technology Works
The Sparklike Laser emits near-infrared light at a 760 nm wavelength, specifically targeting oxygen molecules. This detection allows for the calculation of the insulating gas concentration, critical for evaluating the thermal performance of IGUs.
Key Preparation Steps
To ensure optimal performance, users should:
- Identify any glass coatings using detectors or visual methods.
- Clean both the measuring head and glass surfaces.
- Ensure tight attachment to avoid air gaps or misalignment.
Measurement Best Practices 
- Confirm IGU type (double or triple glazing) before starting.
- Measure from the uncoated side when coatings are present.
- Use device presets for laminated or toughened glass.
- Repeat each measurement to confirm accuracy and spot anomalies.
Avoiding Common Pitfalls
Issues such as dirty surfaces, low light transmission through coatings, or user error can lead to incorrect readings. Regular cleaning, proper training, and awareness of glass types help mitigate these challenges.
Repeated measurements improve data reliability, while standardized documentation ensures traceability and supports continuous improvement.
