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.

General Parameters
- low power
- high sensitivity
- long exploatation time
- short answer time
- operating mode: continuos or impulsive

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.
