VRAE is a flexible multi-gas detector with optional LEL/VOL dual-range flammable gas sensor, electrochemical oxygen (DPPGM-7800) and three (PGM-7800) or four (PGM-7840) electrochemical The gas sensor can continuously detect real-time gas, oxygen and various toxic gases. VRAE is light in weight, small in size, reliable in performance and easy to carry. It can meet the needs of many industries such as gas, petroleum, petrochemical and metallurgy.
