ASTM D4052 Digital Density Meter
U-tube oscillating density meter, electronic liquid density meter is based on the principle of different oscillating frequency when the double U-tube is filled with different media. After pumping the sample into the resonance tube sensor, the measurement data is processed by the single chip microcomputer, it features fast , direct, and has high sensitivity. It consists of a dual tuning fork density sensor, vibrating tube circuit, temperature measuring circuit, CPU, display, constant temperature
