In close cooperation with industry and science, Kruss, Germany has developed digital density meters with U-tube oscillators that best meet the requirements in terms of accuracy, speed, required sample volume and ease of integration into the manufacturing process.
The DS7000 density meters are available in two versions – DS7700 and DS7800. Their only difference lies in the measuring accuracy; all other characteristics are identical. The devices are very robust, compact and yet precise and suitable for nearly all liquids, emulsions, pastes etc. thanks to the chemical-resistant parts made of borosilicate glass and PTFE that are in contact with the sample.
The samples are supplied manually via syringe, semi-automatically via peristaltic pump or fully automatically via autosampler. Highly viscous samples are usually supplied with a syringe; low-viscous to slightly viscous samples can also be supplied with a peristaltic pump or an autosampler. The company provides suitable density meter sets for any working method and any type of sample that include all the required accessories from tube sets to nozzles and adaptors to splash guards for the manual supply of aggressive substances.
The user can also choose between two measurement methods: the measurement with a manual measurement time input and an optimised measurement time thanks to automatic stability recognition. The devices will always require a sample volume of less than 1 ml. The U-tube oscillator is cleaned by rinsing it with the appropriate medium supplied with a syringe or peristaltic pump. Just one keystroke is needed to have the drying unit eliminate all liquid residues. The drying unit DS7060 with its 3/2-way valve allows for a fully automatic drying. The density meters feature a self-explanatory, well-arranged user interface, which makes it easy even for non-expert personnel to operate the device. A state-of-the-art TFT display ensures a clear, bright representation of all the information. The integrated touch-screen tops off the convenient user experience.
