Detection Do’s and Don’ts
10.3.1
Case 1 – Detection through glass
When detecting through the glass, if the infrared laser is incident on the glass vertically, part of the
light reflected by the glass will be received by the device, which will cause the light intensity
saturation or inaccurate measurement result. In such case, the GAZOSCAN™ needs to be pointed
as shown in figure below to avoid receiving the light reflected by the glass.

Case 1: Detecting through glass
10.3.2
Case 2 – Detection through materials with strong absorption or reflection effect on the
infrared laser
Avoid detecting through materials that have strong absorption or reflection effects on the infrared
laser, such as PMMA, laminated glass or anti-infrared glass.
In such case, the methane concentration behind can’t be detected or the measurement result may be
inaccurate.
Case 2: Avoid detecting through anti-infrared or absorbing infrared material
