V-OVG Calibration Gas Generator

v-ovg gas calibration generator.jpg

The Vertical Owlstone Vapor Generator (V-OVG) builds on Owlstone's proven OVG technology. 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 Vapour 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.
