Capable and Versatile
DF-R280
The DF-R280 handles a wide range of requirements, from in-line inspections to laboratory examinations.
The flow sensor features a laminar flow tube that provides high accuracy readings of ± 1%.
The large LCD display shows flow rates and other useful information.
Intuitive and easy-to-navigate interface with simple menu configuration.
Test pressure and differential pressure waveform display.
The influence of the noise generated during the test on the workpiece can be compensated by reducing the test time.
Three languages can be selected such as English, Chinese, and Japanese.
USB port for easy management of test data.
Closest location of the sensor unit to the target capsule.
