Quick-Ox Oxygen Sampling System from Vandagraph Limited. "The Vandagraph Quick-Ox is designed to give true oxygen percentage readings and longer sensor life".

The Quick-Ox offers fast accurate measurement with minimum loss of gas and minimum skill. A by product of this system is the gas flows across the sensor. This prevents high pressures, which can damage the membrane of the sensor and not directly onto the sensor face as in existing Dome sensing system.

This device can be used by any level of diver and is not dependent on skill to achieve accuracy. Calibration is easy and fast by removing the flow divertor and waving in fresh air.

Features

• The Dome is designed to fit flush against the O ring on a Scuba cylinder and also fit into the thread of a Scuba DIN fitting.
• The Dome has been fitted with a concave inlet and a small hole at the end so that the gas builds up in the concave and forces the room air to out of the sampling gas stream.
• The hole size has been chosen to restrict the flow yet allow sufficient gas to enter the sensor and enable the fast response. Venturi effects are eliminated.
• The gas stream is funnelled by the concave on the dome through the hole and then through a one-way valve so that the gas goes in but cannot return back through the dome.
• The one-way valves on the outlet also serves to stop air re-entering the sensor during the reading period.
