OVERVIEW
The V-OVG platform features an innovative new oven design. The larger, vertically mounted chamber allows the use of multiple, physically large or specialist permeation devices.
Owlstone Vapor Generators are compact, cost-effective calibration gas systems, which can generate NIST traceable, precise, repeatable, and accurate concentrations of chemicals and calibration gas standards. The V-OVG is a versatile platform for the calibration of industrial and scientific gas sensors. Using permeation tube technology, a V-OVG system can replace multiple gas cylinders resulting in significant cost and space savings.
The new V-OVG sample oven is 16 times the volume of the OVG-4 model. This larger oven allows gas standards to be produced from multiple and non-standard geometry permeation sources. The V-OVG also features an improved split flow meter with a digital readout and a RS-485 communications module for computer control.
