Pellistor type PC-4x detector of explosive gases is designed to use in devices measuring concentrations of gas and flammable vapours, in explosimeters and systems of monitoring explosion hazard. Because of low power consumption it is especially usable in individual and portable instruments, battery powered or line feeding of limited current output.

In relation to PC-3x type pellistors, the pellistors PC-4x type will be characterized by:

• lower current (lower power consumption)
• possibility of minimizing dimensions

The sensing head type SG is designed to detect and measure the methane concentration in the areas of explosion hazard. Electrical parameters, the metrological range and application area dependent on the head's version. It can be applied in electrical apparatus for detection and measurement methane in devices groups I and II (CH4).

In relation to SG-1 and SG-2 type heads, the heads type SG-14 and SG-24, will be characterized by:

• lower current (lower power consumption)
• possibility of minimizing dimensions

The sensing head type SGp is designed to detect and measure the methane concentration in areas of explosion hazard. The electrical parameters, metrological range and area of application are dependent of the head's version. It is foreseen to gasometric apparatus electrical devices groups I and II (CH4). The head with integrated pump and flow sensor enables the measurements in not easily accessible places.
