ambient air sampler / automatic / fixed

The ECHO HiVol is a standalone automatic instrument designed to be used outdoors even in severe weather conditions.


The Echo Hi Vol uses a Venturi gas meter which gives it many advantages, such as measuring stability in the long term, the possibility to be used in all weather conditions, and reduced sensitivity to staining, thanks to the self-cleaning profile.


The flow measure and regulation in relation to actual conditions allow the user to change the sample head and flow rate without recalibrating the flow meter.
