The micro MICRO Combusitbie Gas Leak Detecor detects gas concentrations through the use of an internal sensor. This sensor is heated during operation. As the heated sensor interacts with gases, the unit immediately indicates to the user that combustible gases are present.

The GD-3308 Combusitble Gas Leak Detecor indicates the presence of combustible gases with visual, audio and vibration feedback mechanisms. It can detect different combustible gas concentration 1-1 OOOppm or 0-1 OOOOppm by setting high and low concentration detection. When the tool senses the presence of a combustible gas, it will tell the operator by LCD display, triggering the appropriate audible alert or providing the appropriate vibration alert. The GD-3308 Combusitbie Gas Leak Detecor comes equipped with an attached flexible 16″probe hose.
