"OVG is a great tool for our corrosion studies in atmospheres polluted with controlled low amounts of contaminants. As well as high precision air flow and gas generation control, modularity and versatility, we especially value the exceptional long-term customer support provided by Owlstone."

OVG for detection of CWS and explosive taggants

"As we develop sensors responding to ppb concentrations of VOCs, our Owlstone eight-channel OVG-4 calibration gas generator has been invaluable with their excellent stability, and are significantly more cost effective than the competition"

"The OVG-4 units work exactly as advertised and I couldn't be more happy with the performance of our system. Also, the support Owlstone have given us throughout has been outstanding"
