Analox Sensor Technology has launched the Sub Aspida, a new portable dual-gas monitor designed specifically for use in locations such as submarines where there are variations in atmospheric pressure.

At launch, Analox has also confirmed that the Dutch Navy have signed a contract for nine Sub Aspidas to be used on their fleet of four Walrus Class submarines.

Vicky Brown, Sales and Marketing Director – Analox Military Systems, said: “The Dutch Navy requires accurate dual-gas monitoring in a compact unit, in an environment which is prone to fluctuations in atmospheric pressure. The Sub Aspida addresses this need, and ensures the submariners remain safe whilst at work.”

From March to May 2010, the Sub Aspida was tested by Lt Leppink of the Dutch Navy in the control room of a submarine.  He said: “We were very impressed with the Analox Sub Aspida.  One of its most important advantages is the pressure-correct read out which remained accurate even during rapid changes in the atmospheric pressure, making it a vital tool to have on board any submarine.”

The Analox Sub Aspida is a compact, portable monitor capable of detecting both carbon dioxide (CO₂) and oxygen (O₂).  By combining continuous monitoring of partial-pressure O₂ and the volume of CO₂, the monitor is ideal for use on submarines.  With a pressure sensor incorporated, the Analox Sub Aspida is the only monitor which automatically corrects O₂ and CO₂ readings in relation to changes in atmospheric pressure, resulting in a more accurate and trusted reading.  This prevents spurious alarms caused by pressure variations typically found on board submarines.

The Sub Aspida offers audible, visual and vibrate alarms.  Where silence is vital, the audible alarm can be disabled.  To ensure its practicality the unit is easy to use, rugged in design and comfortable to wear.  It offers 12 hours of battery life from one charge and can also be powered by a 9 volt DC supply.  The software enables easy configuration, calibration and downloading of data and also ensures optimum performance of the unit by informing what maintenance is required and when.
