Defender520 flow calibratorThe series provides you with everything related to BIOS DryCal technology designed primarily for the occupational health and safety industry. Open it and connect it to the pump for measurement, it's that simple. Immediately use the quick start calibration air sampler, which is a solution that does not require any preparation or cumbersome soap film flow. Alternatively, when you quickly set the continuous measurement pump for flow, manual continuous measurement can be used. Many users of Defender use optional operation modes to simplify calibration work, which is exactly the format you need and like.

Working methods

The 520 flow calibrator samples through a filter or adsorption tube during pump suction, or fills the sampling bag for gas collection and steam during pressure measurement calibration of the pump. It measures values at a certain time or adopts continuous measurement using continuous and burst modes, including user selectable groups from 1 to 100 measurements. To track the long-term stability of the pump, set the time from 1 to 60 minutes to measure and record on your computer at your reading or decide how to view your data - select the measurement unit and use the quick zoom feature (applicable only to Defender520) to display the size and appropriate details.
