Portable Density Meter
Submersible Density Meter
The tuning fork density meter uses the sound wave frequency signal source to excite the metal fork body, and makes the fork body vibrate freely at the centre frequency. This frequency is correlate with the density of the contact liquid, so the liquid can be measured by analysing the frequency. Density, and then temperature compensation can eliminate the temperature drift of the system; and the concentration can be calculated according to the relationship between the density and concentration of the corresponding liquid at a temperature of 20 ℃. This device integrates density, concentration and Baume degree, and has a variety of liquids to choose from.
