Us BIOS traffic calibrator Defender 520 series

First, flow calibrator introduction:

The Defender 520 is a new generation dry gas flow meter with easy calibration and accurate flow rate. It is used by many individual sampling pump manufacturers. It can be used in industrial hygiene, environmental protection and various laboratories. It uses the principle of dry piston movement, which can produce multiple consecutive readings with a single press. Compared with the traditional bubble flowmeter, it is more convenient and fast to use. The 520 model adds the ability to test both temperature and pressure at the same time as the 510.

Second, flow calibrator features:

1, the dry piston principle, easy to use

2, accurate flow control, ISO17025 certification

3. Compact structure

4, large display screen

5, each group of readings up to 100

6, 520 series can be built-in temperature, pressure sensor, optimize the test results
