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
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
Accuracy and precision even at very low concentrations with superior long-term stability and repeatability
Cost savings by replacing multiple, costly gas cylinders
Small quantities of target chemicals reduce the risk of dangerous exposure
Simple to Use
Fast and easy sample replacement removes dangers associated with high-pressure cylinders
Compact footprint for significant laboratory space savings
Owlstone permeation tubes are traceable to NIST standards, and are supplied with their own calibration certificates
