Online sulfur dioxide gas detection alarm

Online sulfur dioxide gas detection alarm

The MIC-600 online sulfur dioxide detection alarm is applied for 24-hour continuous online monitoring of sulfur dioxide gas concentration and temperature and humidity measurement on site. It displays concentration and over limit sound and light alarms on site, and remote data transmission. Adopting a 2.5-inch high-definition color screen to display concentration in real time, and selecting the best brands of electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoionization principle gas sensors in the industry according to different detection gases, as well as high-precision capacitive digital temperature and humidity sensors from Switzerland, MIC-600 advanced circuit design and mature core algorithm processing, a new generation of multifunctional fixed online composite gas detection alarm has been born. The MIC-600 can detect gas concentrations in pipelines, confined spaces, and atmospheric environments, as well as detect gas leaks and the purity of high concentration single gases. The sturdy and durable explosion-proof shell and fluorocarbon paint surface treatment process are suitable for various hazardous areas and corrosive environments with strong acids and alkalis. They are wear-resistant and will not fade or peel off the paint within 10 years.
