Sparklike Handheld™ 3.0

Sparklike Handheld™ 3.0 is the practical and quick method to test IG gas concentration. The technology is based on plasma emission spectroscopy. A high voltage spark is launched in the IG unit’s cavity causing a light emission which is observed and analyzed further. The device is portable and battery operated, thus being practical and quick to use with a measurement time of 2 seconds! Thanks to its small size, it is easy to get a fast reading of gas concentration, whether it’s argon or krypton. The user can simply place the device against the unit, press the button and receive an instant result with high accuracy. Sparklike Handheld™ 3.0 (formerly known as Gasglass Handheld) has become the industry standard for non-destructive measurement – and used by insulating glass manufacturers, window and door manufacturers and testing laboratories worldwide.

The handheld device is not designed to work with laminated glass. Laminates aren’t all built using the same glass types/substrates and aren’t all the same thickness. Because of that variability, it’s possible it would work with a few as an exception, but it generally will not work with most.


Double glazing with one low-e surface is the best option for Handheld. The spark doesn’t go through the low-e surface. Test from the clear pane side and the spark lands on the inside surface of the low-e pane without going through it.

Handheld device cannot be used in the field.

If you have same coating in both glasses, then the spark will not go through the unit. In any case, if you have Handhelds, you can simply try to see if the spark goes through the unit. If the spark goes though, everything should be fine, and if the spark spreads to the surface, then it doesn’t work.

We have recommended 30min warmup just in case you have a factory that is very cold inside, because frozen devices could have quite jumpy signals right after start, but they should settle down after some time. The necessity of the warmup time is questionable because I have seen that sometimes it matters, and sometimes not. Basically, the nonlinearity of the CCD could be the factor that makes the difference (not 100% sure), and there are differences between component batches. What happens, if something happens, is that the readings drift to slightly higher when the device warms up, so average of 80.0% could drift to 80.5%-81.0% or something like that. The temperature drift is bigger in low concentrations, so you should not see any drift in 97.5%.

There are validations related to certainty of measurements, but no such criteria has been developed yet by Sparklike. Having the annual calibration service performed on your Handheld device gives a tolerance of +/- 2%.
