FireBoss 100 Carbon Monoxide Sensor -All CO sensors are not alike. The FireBoss toxic 0-25-100-500 ppm CO sensor line has been re-designed and enhanced over a period of two decades of underground mining use, and has evolved as a tough, dependable product with exceptionally long-term stability. Others are often plagued with temperature problems and short life expectancy. We frequently observe sensors still working on their first electrochemical cell after 5- 8 years of grueling service.
