Features
With concentration and alarm display functions, the gas concentration and alarm status can be seen at a glance on-site, helping to ensure the safety of workers.
During maintenance, the output can be checked at the detection unit, and calibration can be performed by one person, leading to cost reductions.
The adjustment system uses a magnetic stick, making maintenance easy.
Waterproof and dustproof structure (protection class IP65)
Hydrogen/acetylene explosion-proof structure (Ex db ⅡC T5 Gb)
