Description
Overview
GAOTek portable alarm gas detector is a personal anti-gas detector that can continuously and simultaneously detect a variety of gas concentrations. TFT screen with large colour display, up to 4 gas concentrations at the same time, according to the active sensors, the model of the gas concentration display can be automatically adapted. shell is designed with rubber coated plastic mould, which has waterproof performance. The detector can meet the requirements of explosion-proof, can be widely used in iron and steel metallurgy, petrochemical, emergency rescue, industrial safety and other industries.
