Differential pressure densitometerRK080-Nanjing Rankong Technology Co., Ltd

RK-080 based on microprocessor electronic switching device, signal processing, calculation and diagnosis function in a body.

Besides with convincing accuracy of measurement and reliability. It can direct communicate with PC through RS485 or Hart interface,

under the software environment for professional users, the user can direct set the online node configuration, fault diagnosis and data records.

When measuring density and temperature, it also can calculate the basic density.°API, brix and concentration ratio, mass ratio, volume fraction and so on.
