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
