New flow calibrator goes above and beyond the ordinary

Mar 18 2021

Dado Lab have just added a flow calibrator to their portfolio. They did not simply wish to have the usual features available from all the other manufacturers, their plan was to offer something different, something better.

To describe the CF1 as a "flow calibrator" is quite an understatement  because, of course, it measures the actual/normalised flowrate but it also measure the volume passing through the cell, ambient pressure, gas temperature and pressure drop of the line.

A second version named CF1-UR is available and, through an external sensor, also measure ambient temperature and relative humidity.

The CF1 features an annular laminar flow cell which grants a flowrate range with a very wide dynamic 1:100 (from 0,45 to 45 l/min) and capability to measures flows both sampled or delivered by the pump.

CF1 is compact and light (only 300 gr) and is equipped with LiPO batteries which makes it ideal  as a secondary reference for field operations. All CF1 sensors can be ISO17025 certified, which makes it suitable also as primary reference for flowrate, volume, pressure, temperature and rH%  in the lab.

CF1 has also wireless communication capabilities, it will be supplied with USB dongle for direct communication of all the readings through the software (under development) for long lasting sampler tests. The software will also allow users to program the certificates into the unit.

A highly accurate calibration is available as an option to give the unit a flowrate accuracy of 0,8% ± 0,1% f.s.! The CF1, despite all its capabilities is also very competitively priced.
