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.
