The KD-12 series of ATEX gas detectors is an aluminium cased lightweight and compact detector. |
- Rugged, compact and lightweight.
- LED local display shows the gas concentration and alarm indication.
- Explosion-proof (ATEX, IECEx and TIIS approved).
- Water and dust-proof construction (IP65).
- All setup and maintenance can be performed easily on site by one person.
- The simple plug-in sensor module makes it easier.
- HART model is available (KD-12AH/BH).
