The smallest gas detection instrument for the measurement of up to 6 gases. This detector reliably detects explosive, combustible and harmful concentrations of O2, Cl2, CO, CO2, H2, H2S, HCN, NH3, NO, NO2, PH3, SO2, O3, Amine, Odorant, COCl2 and organic vapors. Draeger infrared sensors can generally be used for up to eight years. This advanced technology reduces the cost of ownership considerably because less replacement sensors are needed. In addition, a sensor calibration is only necessary every 12 months which reduces maintenance costs. An optional external pump which can be operated with hoses up to 30 m or 98 ft. in length is the perfect solution for pre-entry measurements in tanks or pipelines. The small and reliable gas detector is suitable for use in areas classified as zone 0, which are areas where explosive atmospheres are always to be expected. Consisting of basic instrument with an integrated data logger, support CD, manufacturer‘s and calibration certificates.
