Easy in Use

The VariDens is a robust , sealed, stand-alone system with the flexibility to handle any measuring inquiry in even the harshest environments. Density determination for liquid substances and concentration measurements are made simple with the modular display that can be adapted and combined with the other VariSeries instruments. As part of the VariFamily the VariDens can be used by different users simultaneously, enabling lab managers to handle and sign off data while lab technicians are still measuring.


SCHMIDT + HAENSCH offers reliable density and concentration measurement solutions for the food and beverage, pharmaceutical, chemical, cosmetics, petrochemical industries, and more. By ordering the pharma-ready version of the VariDens, you will receive all documents, options, and methods to comply with the 21 CFR part 11 standard. Multiple reference alcohol tables, precision density resolution, USB and ethernet, serial output, and a wide range of accessories solve the most challenging applications.

All our benchtop instruments are built in enduring and robust materials, ensuring the instrument’s longevity in even the harshest conditions.

Product in depth

The SCHMIDT + HAENSCH VariDens Density Meter offers an optional moisture and air pressure sensor, and accurate temperature control programs provide the extended usage also in difficult environmental conditions. Made in Germany and stress tested, the VariDens density meter is prepared for a long product lifecycle and durable operation. Intuitive user-friendly software and the large Color-TFT Touchscreen reduce the setup times for protocols and add powerful trouble-shooting capabilities. Common accessories and robust exchangeable fittings reduce installation expense and save time evaluating third party products. The VariDens Density Meter can be combined with other SCHMIDT + HAENSCH laboratory instruments, such as Refractometers, which allow this instrument also to be used for complex analyses. This unique modular capability combined with advanced interior design sets a new standard for density measurement instruments. The VariDens ensures for you a consistent manufacturing process and allows tighter tolerances on the results, reducing costs and increasing product quality.
