Intrinsically Safe Portable Density Meters: DMA™ 35 Ex and Ex Petrol
The intrinsically safe DMA™ 35 Ex and Ex Petrol portable density meters measure the density and concentration of your sample directly out of the sample container. With ATEX protection according to class II 2 G Ex ib IIC T4 the instruments are ready for safe operation in hazardous environments. The DMA™ 35 Ex version is designed for concentration measurement of flammable or explosive chemicals whereas DMA™ 35 Ex Petrol is the solution for measurement of petroleum samples. Their robust and lightweight design enables long-term on-site operation even in harsh working environments.
