QB1 is a family of portable constant flow samplers designed to be used in every air sampling application requisting from low to mid-flow capabilities.
The QB1 has been developed to satisfy the every day job of technicians; it’s easy to use, rugged and reliable thanks to the built-in protections for particulate matter and liquids, which are the main responsibles for damages to the pump and dry gas meter.
More protection means less service and more availability of the instrument.
All the versions are capable of automatic pressure drop compensation, granting high flow constance, even fort longterm operations.
The QB1 are equipped with Dry Gas Meter, high precision flowmeter and thermometer for volume normalization, as requested by the standards.
The pneumatic circuit has been designed to eliminate flow pulsations due to the use of diaphragm pumps.
