The density meter DMA 4100 M provides unparalleled ease of use and state-of-the-art digital density measurement at an attractive price. Among the DMA 4100 M density meter's numerous applications are its use in industrial quality control, in research, at authorities and at standards organizations
Features

 

Technology: Anton Paar’s DMA density meters combine the groundbreaking oscillating U-tube principle, the integrated reference oscillator, highly accurate platinum thermometers and a full-range viscosity correction to provide exceptional measurement performance. The new features of DMA Generation M add an outstanding level of user confidence and comfort
 
Adaptable configurations: Use the function keys below the touchscreen, a mouse or an external keyboard if you are working in a harsh environment. Enter sample identifications through a keyboard, a bar code reader, or via other means. Connect a large PC monitor or touchscreen to read the results or operate the instrument from afar. Choose from common density units such as g/cm3, kg/m3, pound/gallon and employ “customer tables” to calculate concentrations in units such as %w/w, %m/m
