Owlstone develops, manufactures and supplies advanced chemical detection solutions across a wide range

of markets and applications.

The Owlstone technology detects a wide range of chemicals with extreme sensitivity and selectivity.

The technology has numerous applications - across industries from security and defense to automotive

and healthcare - that depend on the rapid, accurate detection and measurement.

Owlstone works with market leaders within these applications to integrate its technology into next

generation chemical sensing products and solutions. Owlstone offers a unique combination of benefits,

including: small form-factor, minimal power consumption, reduced false-positives, and a customizable





The Owlstone V-OVG is a system for generating precise, repeatable trace concentrations of gases.

By using permeation and diffusion tube technology, a range of concentrations from low parts per billion

to high parts per million levels can be achieved.


The large permeation oven allows the use of up to 6 permeation tubes to create multiple-component

mixtures, or a diffusion tube to generate high ppm concentrations.


  • High number of available compounds

  • Generation of multiple gas mixtures

  • Fast and easy sample replacement

  • High accuracy and precision, even at lowest concentrations

  • Can replace multiple expensive gas cylinders






The OHG-4 is a versatile humidity generator that is used to produce a range of relative humidity

concentrations from 1 to 90%rh (±1%). When used in the GEN-SYS, in combination with an OVG-4 and

an OFC-1, it can generate a wide range of vapor standards, suitable for calibration of sensors, especially

gas sensors. In the OHG, the airflow is controlled by a mass flow controller.


A flow suitable for the application is set using the front panel Wet Air Flow control, this controls the mass

flow controller (MFC). Downstream of the MFC the airflow is split into two flow paths, the first of which

bubbles through the water reservoir.


Downstream of the reservoir the two flows are recombined. The ratio of the two needle valve settings controls

the humidity of the output air.
