Pressurised environments are unique, as are the gas detectors used to monitor the area. The Sub Aspida is a compact portable atmosphere monitor, which is easy to operate and maintain.

Product Overview

This rugged and robust analyzer detects both carbon dioxide (CO2) and oxygen (O2) in pressurised environments from high altitudes to beneath the waves. Due to it's size, it is perfect as a secondary monitor.

Unlike industrial sensing monitors, the Sub Aspida was designed with pressure corrected sensors, giving you 100% confidence in your readings.

'I have worked with the Aspida, it is a small and easy to handle machine that we used to monitor the atmosphere on board when the CAMS was out of order.
I always find Analox equipment easy to handle , reliable and after-sales from Analox is excellent' Jos Bogaert - Retired RNN Submariner

  • It is the only portable monitor to be pressure corrected ensuring no false readings are given 
  • The Sub Aspida is compact in size (127 x 44 x 90mm LxDxW)
  • The oxygen (O2) sensor can be calibrated on air, reducing costly gas requirements and making you self sufficient in the maintenance of the sensor 
  • The carbon dioxide (CO2) sensor only needs calibrating every 12 months

The Sub Aspida is used in applications such as: 

  • Submarine rescue vehicles
  • Submarine escape and rescue
  • Submarine atmospheres
  • Aircraft

Oxygen (O2)
Carbon dioxide (CO2)

We want to ensure that your Sub Aspida is maintained to its optimum performance level. We have various support packages which you can sign up to, ensuring replacement sensors and maintenance is pre-arranged for you.
