The Xitech Model 1060H is a high-vacuum bag air sampler built for clean, low-flow VOC and ambient air collection in the field. It's the stronger sibling in the 1060 series, pairing a heavier-duty diaphragm pump and battery with the same reliable sampling method: air is drawn straight into a 1- or 2-liter Tedlar-style bag without ever passing through the pump itself, so the sample stays uncontaminated.
