Overview
Portable Submersible Density & Viscosity meter VDM-250 SERIES best suited for liquid density, viscosity, concentration and temperature measurements directly in the storage or process tanks (up to 30 meters depth). No labor extensive and errors critical sampling required. Instead, the sensor of VDM-250 SERIES is submersed at any required level and record spot density/viscosity and real temperature at that point directly in the liquid. The operation personal can get in minutes the average density/viscosity in the tank and its density / viscosity / temperature / level profile, for example, at every meter. Hundreds of measurements can be stored locally and future transferred to a PC or printer via built-in bluetooth connectivity. The VDM SERIES has robust design for heavy duty year round indoor or outdoor operation, even in severe climatic conditions at –40°C to +85°C (-40°F to +185°F).
