Can Sparklike Handheld™ measure triple units?

No, you cannot use Handheld for measure triple units. You need Sparklike Laser Portable™ or Sparklike Laser Integrated™ for that.

All devices within the Sparklike Laser™ product line, are based on TDLAS (Tuneable Diode Laser Absorption Spectroscopy) that allow the measurement of insulating gas fill without breaking the insulating glass unit or without having any extra components inside. By using this technology, the device measures oxygen and from there, the amount of argon, krypton, or other insulating gas, can be calculated. TDLAS enables non-invasive measure gas concentration of triple units even through coating and laminated glasses.
