Sparklike Laser Portable™ 2.0

Non-destructive insulating gas measurement device for double & triple glazed IGUs with coatings & lamination.

About Sparklike Laser Portable™ 2.0

Sparklike Laser Portable™ 2.0 measures insulating gas concentration on triple and double glazed units. The device measures oxygen, and the results are converted to concentration of argon, krypton, and other insulating gases. The battery-operated, portable device is based on laser technology (TDLAS).


  • Compact measuring head with New ErgoGrip™ – three handles and start-buttons, easy to handle in different measuring positions
  • Smaller main unit case with 150 mm pneumatic wheels – easy to maneuver
  • Vacuum gripping to the IG unit – light signal when reading and vacuum grip is released
  • Insulating gas check at any point of the production flow
  • Measured units can be delivered to the end user and checked again at a later date
  • ErgoGrip™ handles and three start buttons for any measurement position
  • Compact trolley unit for easy maneuverability – enables on-site measuring
  • Determines accurately the concentration of insulating gas, and glass and cavity thicknesses
  • Measures the residual oxygen – any insulating gas can be checked
  • Patented TDLAS technology
  • Portable device with battery
  • Technical support with remote connection

Frequently Asked Questions

Yes, the Laser Portable™ 2.0 is capable of measuring Quad IGUs. The first measurement will be taken as if a triple, and the second measurement will be taken as if a double, from the opposite side.

Here is an illustration showing how 2 measurements can be taken to test gas concentration in a Quad pane IG.

Measuring quad IGs using Sparklike Laser Portable 2.0

The Laser Portable 2.0 is more portable than the original laser portable while it’s in operating mode. The original Laser Portable was configured in a larger case with the measurement fitting inside for shipping and transport.

The Laser Portable 2.0 is shipped in two cases with the measurement head having its own case. This results in a much smaller case when in the operating mode. In addition, the measurement head of the 2.0 is smaller with additional handles and additional measurement start pushbuttons. Sparklike has also made improvements with the cable connections by moving the connectors to the outside of this smaller case.

The Laser Portable 2.0 will measure through most all low-e coatings/laminate. An IG unit with coatings on surfaces 1 and 2 could be measured if the opposite lite was clear and surfaces 3 and 4 had no coatings.

Regarding the air space thickness, the accuracy is the same as with the glass thickness measurement: 50 micrometers.

Regarding the air space thickness, the accuracy is the same as with the glass thickness measurement: 50 micrometers.

Yes. The Laser Portable will measure both cavities through most all lowe coatings.

The Laser Portable unit can track results, which can be saved to a USB memory stick. It’s not integrated into your systems and will not have the report capability other than the .txt file.

Yes, the barcode reader can be added later, and remotely.

The results of measurements taken with the Laser Portable can be downloaded and transferred using a USB memory stick that can be installed in the portable. The Wi-Fi option allows the results of the measurements to be immediately sent to the company’s information system. This eliminates the need to remove the USB memory stick and transfer the data to a computer. WiFi can be added afterwards; we cannot do it remotely.

he Laser Portable 2.0 uses a different technology than the Handheld.  

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. Different algorithms are used for argon and krypton measurements. The ability to measure krypton is an option and is not normally included with most Handhelds. 

The Laser Portable 2.0 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.

The tolerance of the Laser Portable is much better than the Handheld. The readings are within +/- 1% to levels as low as 1%. The accuracy does not decrease with lower gas levels as does the Handheld.

The Laser Portable measures the gas content of the first cavity and then the gas content of the entire unit. It then calculates the content of the second cavity. In most cases the instrument is not influenced by lowe coatings, laminations, or thicker commercial glass. Glass thickness “presets” can be entered into the instrument to assist in the measurement of thicker glass.

The Laser Portable is not affected by background lighting and can be used in the field to measure the content of installed insulating glass units.
