QB1 Constant Flow Sampler

QB1 is a family of portable constant flow samplers designed to be used in every air sampling application ranging from low to mid-flow capabilities.

 

The QB1 has been developed to satisfy the everyday 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 reasons for damage 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 constants, even for long-term operations.

 

The QB1 is 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.

PMx Giano & Gemini

The common heart to both models is the multi-purpose core unit (MPC) which manages the sequential sampling on a single or double channel.

 

The MPC particular concept allows both outdoor cabinet solution or the 19” rack installation in shelters or mobile labs.

 

Particular attention is paid to the systems engineering with the target to reduce the number of parts, which increases the reliability and reduces the size and weight. Giano and Gemini weigh only 35kgs without considering the pump/s and support stand.

 

The MPC and the outdoor cabinet are designed to have forced internal air recirculation which helps to keep the ventilation tube, filter under sampling and exposed samples at ambient temperature.

 

The optional air conditioning unit, required for applications where ambient temperature values can be particularly high, keeps the filters area temperature below 25°C in case of ambient temperature exceeds 25°C.

 

The air conditioning unit is placed below the cabinet and offer the advantage to give high cooling performances. Despite other solutions, the air conditioning system doesn’t require special protections or insulations for the filters tanks, which can still be easily accessed and changed in the field.
