Sub Aspida

Personal CO2/O2 Monitor

The Sub Aspida is the ideal solution to protect you and your team from the dangers of enriched oxygen (O2), carbon dioxide (CO2) or inert gas leaks.

The Sub Aspida is a personal, portable monitor which is used to detect levels of carbon dioxide (CO2) and oxygen (O2) in pressurized environments.

Key features

  • 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
  • OLED (Organic Light Emitting Diode) display
  • Pressure compensated CO2 & O2 sensors
  • Rechargeable battery-operated (NiMH)
  • Data logging
  • Man-down alarm
  • Can offer continuous monitoring or spot checking
  • Audio, visual and vibration alarms
  • TWA (Time Weighted Average) Alarm
  • User maintainable
  • Can be worn on the belt or clipped to a panel
  • Pressure range of 700-1200mbara
  • Maintenance reminders as standard

Legislations / Standards

For the transportation of large quantities of dry ice, the FAA (Federal Aviation Administration) advise that:

  • CO2 sensors installed or carried in the aircraft or worn by the pilots and other crew members will assist the operator and crew in recognising hazardous concentrations of CO2 and implementing effective risk controls.
  • Pilot training on specific conditions and procedures can improve pilot decision-making in the event of a CO2 detector alert or other system abnormalities.

To persons conducting operations under Title 14 of the Code of Federal Regulation (14 CFR) Parts 121, 125, 129, 135 on safety issues related to the transportation of COVID-19 vaccines by air, which may require larger than typical quantities of dry ice for preservation.

Operators must comply with applicable federal regulations pertaining to the carriage of dangerous goods (49 CFR parts 171-180).

Additional Information

CO2 & O2 Monitoring

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

The Sub Aspida has been upgraded to support those who work at high altitude.

Pressure tested to 10,000 ft or 700 mb, the Sub Aspida will remain accurate and reliable when monitoring CO2 and O2 in the atmosphere, meaning you can concentrate on the job at hand!

Accuracy

The Sub Aspida also finds itself at home inside submarine rescue vehicles (SRV), tourist submarines, and research submarines. The Sub Aspida produces accurate readings over a pressure range of 800–1200 mb without false alarms. Having the option to power the unit from AA alkaline batteries in the event of a submarine losing power makes it a perfect backup safety monitoring system in order to comply with the rules around SRVs and life support stores, with emergency monitoring required for a minimum of three days.

Regulations

For the transportation of COVID-19 vaccines requiring large quantities of dry ice, the FAA (Federal Aviation Administration) advises that:

CO2 sensors installed or carried in the aircraft, or worn by the pilots and other crew members, will assist the operator and crew in recognizing hazardous concentrations of CO2 and implementing effective risk controls.
Pilot training on specific conditions and procedures can improve pilot decision-making in the event of a CO2 detector alert or other system abnormalities.

This applies to persons conducting operations under Title 14 of the Code of Federal Regulations (14 CFR) Parts 121, 125, 129, and 135 on safety issues related to the transportation of COVID-19 vaccines by air, which may require larger than typical quantities of dry ice for preservation.

Operators must comply with applicable federal regulations pertaining to the carriage of dangerous goods (49 CFR Parts 171–180).

Pressure

Whether you are measuring the atmosphere in an aircraft at altitude or in a submarine under the sea, the Sub Aspida can take the pressure.

It is critical to use pressure-compensated sensors in these environments; otherwise, it’s likely that you will get false readings, exposing your team to potentially dangerous levels of gas.

Relax—let the Sub Aspida take the pressure.

Applications
  • Submarines
  • Submarine DISSUB
  • Medical
  • Aircraft

Frequently Asked Questions

How do I calibrate using the Sub Aspida Configuration Software?

The process for Sub Aspida calibration is very simple, please follow these steps:

Step 1:

Connect your aSub Aspida to the PC via a USB A to USB lead

Step 2:

Open the Analox Sub Aspida shortcut

unnamed 26

Step 3:

The software should load with your device identified under found devices

unnamed 27

Step 4:

Select your device (under found devices (click the icon) then click sensor settings

unnamed 28

Step 5:

Select the sensor you wish to calibrate and click calibrate

unnamed 29

Step 6:

In the calibration window, click next

unnamed 30

NB. it is always best to low calibrate prior to high calibration

Step 7:

Select low calibrate the sensor, and change the gas content value to the content of your low calibration gas (in ppm) (100% N2 would be preferable)

Step 8:

Click next

unnamed 31

Step 9:

Follow the instructions for connecting regulator to a gas cylinder and click next

unnamed 32

Step 10:

Follow the instructions for connecting the flow adapter to your device and click next

unnamed 33

Step 11:

Turn the calibration gas on and click next

unnamed 34

Step 12:

Wait for the reading to stabilize and click calibrate

unnamed 35

Step 13:

Then move on to the sensor’s high calibration. The instructions should guide you through this step by step.

How do I change the Oxygen sensor on the Sub Aspida?

The Oxygen sensor in my Sub Aspida is depleted, I have purchased a replacement however I am unsure of the cell replacement procedure.

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

My Sub Aspida will not calibrate. It doesn’t matter what span gas I use, whenever I press Cal O2 I get an x on the screen (calibration failed)

It sounds like the O2 cell has depleted. As the cell depletes due to oxygen exposure its output reduces. The Sub-Aspida accounts for this and displays a corrected reading. However when the cell depletes too much, the Sub-Aspida refuses to calibrate, this is to prevent incorrect readings from the Oxygen cell. Please contact your vendor and order a new Oxygen cell part number: 9100-1060A
