VariDens Series

VariDens Series

The VariDens benchtop density meter offers precise and reliable measurements. With the proven oscillating U-tube principle, the VariDens provides density and concentration measurements of pharmaceutical products, chemicals, and petrochemicals.
The VariDens density meter offers an optional humidity and air pressure sensor, and precise temperature control ensures extended use even under difficult ambient conditions. Available accessories and interchangeable fittings reduce the installation effort and save time when evaluating products from other manufacturers.
The modular design allows the VariDens to be combined with other VariFamily instruments setting a new standard for density measurement instruments.

  • Integrated reference oscillator
  • Fast temperature control
  • Automatic detection of gas bubbles
  • Modular connectivity to your internet browser and tablet or device of your choice
  • An intuitive user interface, multiple users
  • Easy cleaning
  • Compliant with 21 CFR part 11
  • ELN/LIMS ready

    The SCHMIDT+HAENSCH VariDens Density Meter is a rugged, sealed system designed for continuous density measurement in a broad range of applications with the flexibility to handle any measuring inquiry in even the harshest environments.

    Intuitive, user-friendly software and the large, color-TFT touchscreen interface reduces the setup times for protocols.

    The VariDens Density Meter can be combined with other SCHMIDT+HAENSCH laboratory instruments enabling lab managers to handle and sign off data while lab technicians are still measuring.
