What are the main differences in measuring technology between the Sparklike Laser Portable™ and Sparklike Handheld™?

Sparklike Laser Portable™ and Sparklike Handheld™ uses a different technologies to analyze gas levels in IGUs.

Spark Emission Spectroscopy (SES) detects the gas levels

The Handheld uses Spark Emission Spectroscopy (SES) to determine the gas levels. The instrument looks at the intensity and the color of the spark to make its measurements. Background lighting can be detrimental to the operation of the Handheld.

TDLAS penetrates the glass and measures oxygen

Tunable Diode Laser Absorption Spectroscopy (TDLAS) measures gas content.

The Laser Portable 2.1 uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) to determine the gas content. By measuring the amount of the laser signal that is absorbed by the oxygen within the IG unit, the instrument calculates the gas content. The Laser Portable does not determine the type of gas within the unit. It cannot determine whether the insulating gas is argon, krypton, or a mixture. The Laser Portable also measures the configuration of the unit and supplies the dimensions of the glass, cavity thickness and overall unit thickness. Therefore, Laser devices are have more features to analyze gas levels in IGUs.

Both Sparklike Laser Portable™ and Sparklike Handheld™ are a good combo to measure gas concentration level in different situations and glass types.
