The Dräger PEX 3000 transmitter detects flammable gases and vapors at concentrations below their lower explosive limit (LEL), ensuring early warning and enhanced safety in potentially hazardous environments. It enhances your plant’s explosion safety by delivering early detection. Using a catalytic bead sensor, it ensures stable long-term performance and delivers rapid response times — typically within seconds of gas exposure.
