ADM Aspida

HYPERBARIC CHAMBER MONITOR

In 2000, IMCA released a reference document D 023 ‘Design for Surface Orientated (Air) Diving Systems’. Within the document, there was a recommendation for an oxygen (O2) monitor.

In response to the requirement, Analox designed the ADM Aspida.

Key Features

IP65 rated, ensuring the unit is dust tight and protected against water
The unit can be used to analyze the air quality from a portable decompression chamber
ADM Aspida can be a dual monitor by adding a carbon dioxide (CO2) sensor to the monitor
The ADM Aspida is supplied with datalogging function as standard, assisting you in keeping records
Optional faceplate to make it panel mounted

Industries that use the ADM Aspida for hyperbaric chamber monitoring

The ADM Aspida is part of the Aspida family. Manufactured in a small and rugged portable case, it is a cost-effective oxygen (O2) and carbon dioxide (CO2) monitor. Operator maintained ensures minimal downtime and reduced running & maintenance costs.

The ADM Aspida is available with sensors to monitor O2 only, CO2 only or dual gas.

How do I connect an SDA flow meter panel to my ADM Aspida?

Analox recommends that 6 mm outer diameter and 4 mm inner diameter PVC tubing should be used with this product.

The gas inlet at the rear of the SDA flow meter panel is the lower of the two gas ports. The gas outlet from the rear of the SDA flow meter panel is the upper of the two gas ports.

Connection of the ADM Aspida should be made from the SDA flow meter panel gas outlet port, through the hole to the left of the ADM Display and then connected to the flow adaptor (which is fitted to the front of the ADM Aspida).

How do I change the Oxygen sensor?

This is understandable as the procedure is a little fiddly. The best way to explain this is by video:

Amazingly Affordable

With a high IP rating, easy calibration functions and data logging, the ADM Aspida, a hyperbaric chamber monitor, offers an amazingly affordable price point for a great specification in the commercial diving industry.

Many Options

The ADM Aspida is a cost-effective, operator-maintained monitor, developed in response to IMCA’s DO23 – “Design for Surface Orientated (Air) Diving Systems” reference document in 2000. It can be panel-mounted to your chamber panel or in dive control.

It can also be used to analyze air quality from a portable decompression chamber. There is an option to purchase O2 only, CO2 only or dual gas.
