    A1: What is a density meter used for?
    Q1: Density meters are instruments that measure the density of a sample liquid or gas. Digital density meters are used in the pharmaceutical, petroleum, chemical, and food and beverage industries for quality control and in research and development.

    A2: How does a fork density meter work?
    Q2: The Fork Density Meters use vibrating fork technology to measure density directly, and can be used in process control where density is the primary control parameter for the end product or as an indicator of another quality control parameter, such as %solids or %concentration.

    A3: How to use a density meter?
    Q3: Density meters work by measuring the oscillation of a glass tube that contains the sample. There are digital density meters that can measure specific gravity and refraction index as well as the density of a sample.

    Tips: Why choose a tuning fork density meter?

    the tuning meter equipped with a microprocessor-based electronic switching device that integrates signal processing, calculation and diagnostic functions. In addition to its convincing measurement accuracy and reliability, it can communicate directly with the PC through the RS485 interface. Under the ADView software environment, users can directly perform online node configuration, fault diagnosis and data logging. While measuring density and temperature, it can also calculate basic density, °API, Brix, concentration percentage, mass percentage, volume percentage, specific gravity and other parameters.
