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 6 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). Backlighted LCD facilitates nighttime operation.
