V-OVG

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

  • More versatile–a bigger, vertical oven that holds up to 6 standard permeation tubes
  • Easier to use–digital split flow meter readout
  • Suitable for multiple permeation sources
  • Easy–access top entry oven
  • Optional RS-485 connection

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.

  • V-OVG's vertical oven holds up to 6 permeation tubes
  • Wafer device/diffusion tube
  • Digital control of permeation oven temperature, sample flow, and split flow enables fully automated generation of calibration gases. Easily add parallel channels.
  • Vertical loading, large-bore oven for multiple permeation tubes and diffusion tubes.

V-OVG and OVG-4

The three principal differences between the calibration gas generators are listed below. V-OVG has:

  • Vertical oven compatible with diffusion tubes
  • Large-bore oven can hold up to 6 permeation tubes simultaneously
  • Digital control of split flow and sample flow
