ADM Aspida

Hyperbaric Chamber Monitor

ADM Aspida oxygen and carbon dioxide monitor

In 2000, IMCA published guidance document D 023, Design for Surface Orientated (Air) Diving Systems, which included a recommendation for oxygen (O₂) monitoring. In response to this requirement, Analox developed the ADM Aspida.

Part of the wider Aspida range, the ADM Aspida is housed in a compact, rugged portable case and provides a cost-effective solution for monitoring oxygen (O₂) and carbon dioxide (CO₂). The unit is designed for operator-level maintenance, helping to minimize downtime while keeping ongoing service and maintenance costs low.

The ADM Aspida can be configured for oxygen-only, carbon dioxide-only, or dual-gas monitoring. With a high IP rating, straightforward calibration, and integrated data logging, it offers a practical and reliable solution for hyperbaric chamber monitoring within the commercial diving sector.
