Description
GP-1000 72-0076-CH4
The Combustible Gas Monitor Model GP-1000 is a gas monitor designed to provide continuous monitoring of exposure to combustible gas in hazardous areas. The measuring range of GP-1000 is 0-100% LEL. The gas sample is sucked in by built-in micro pump. Power supply is only with four series connected Alkaline AA batteries. Battery exchange in a hazardous area is not performed.
