KGD - MQ - 534 Toxic and Hazardous Gas Detection (Alarm) Instrument
Product Introduction
The KGD - MQ - 534 Toxic and Hazardous Gas Detection (Alarm)
Instrument adopts ECD electrochemical technology and is mainly used
for detecting and alarming CO/H2S gas leaks in fields such as
natural gas, coal - bed methane, landfill, sewage treatment, and
anaerobic fermentation.
Product Features
- Adopts long - life electrochemical technology to accurately measure
CO/H2S.
- Can be used in an oxygen - free environment.
- Has temperature compensation and automatic zero - point correction
functions.
- Long service life, with no sensor poisoning phenomenon.
- Explosion - proof grade: Ex d ⅡC T6 Gb, meeting the safety alarm
requirements for gas leaks in multiple fields.
