PD-12 Detector type gas detector
A suction type ATEX detector with a very strong design. Suitable to detect a wide range of flammable and toxic gases in industrial applications and locations with limited access. A unique detector in an ATEX enclosure with built in pump. There are 3 models available:
PD-12A for measurement of combustible gases in ppm range PD-12B for measurement of combustible gases in %LEL range PD-12C for measurement of combustible gases in %vol. range
Also available as SIL 1 version. |
Features
- Small and lightweight with concentration and alarm display
- Extractive type with hydrogen explosion proof (Ex d IIB + H2 T4X)
- Detecting decreased flow rate function except PD-12C (option)
- Environmental friendly product
- Water and dust-proof construction (Degree of protection: IP65)
