CF1 Flowrate calibrator
Flowrate calibrator
CF1
Dado Lab CF1 is the compact and versatile battery-powered digital multiparameter calibrator, designed for the verification and calibration of personal, environmental, and emission samplers. It is ISO17025 certifiable and compliant with international standards.
It simultaneously measures flow rate, volume, and ambient pressure, and with the optional external probe, it can also measure ambient temperature and relative humidity.
The flow rate is based on a mass sensor with a laminar cell, providing a 1:100 dynamic range in a single device, with two possible measurement ranges: 0.45 ÷ 45 Nl/min in the standard version and 0.05 ÷ 5.0 Nl/min in the LF version.
It displays both actual and normalized conditions for flow and volume.
