Petro Scientific Density Meter
DM-3004 / DM-3005A / DM-3005
Working under the principle of U-tube vibration, it can measure liquid density quickly, and has the functions of electronic excitation, vibration frequency counting and display. By injecting a small amount of samples into the vibrating sample tube, the density of the sample can be calculated according to the change of the vibration frequency of the sample tube and the calibration data.
