Aspida
PERSONAL CO2/O2 MONITOR
The 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.
Key Features
- IP65 rated, ensuring the unit is dust tight and protected against water
- Data logging capability
- Man down alarm
- Time Weighted Average (TWA) monitoring
- Rechargeable batteries
- Intelligent software – up to 2 users registered to one unit
- User changeable alarms
- We recommend: 23.5% for oxygen (O2) enrichment (As per NHS SOPS/EH40/OSHA); 19.5% for oxygen (O2) deficiency 0.5%; & 1.5% for carbon dioxide (CO2) enrichment
Resources for the Aspida
The Aspida is a robust, high specification personal oxygen (O2), carbon dioxide (CO2) or dual (O2 / CO2 combined) monitor which can be worn on a belt or even wall mounted as a backup to a primary safety system.
The Aspida, (Greek for Shield) helps you comply with the regulations, will remind you when maintenance is needed and it safeguards the user from the gas risks.
When you need hassle free, personal protection, choose the Aspida.
The process for confidence testing the Aspida units is similar to the calibration process as described in the product user manual.
The procedure below is similar to testing carried out by Analox when validating the devices are operating within specification:
1. Connect the supplied flow adaptor to the device (PGA-401DK)
or
2. Connect the free end of the flow adaptor hose to a flow regulator (SA7L705XFLIND)
3. Fit the flow regulator to a cylinder of 20.9% O2 (In N2) (SA7L11009)
4. Set the flow rate to 0.2lpm
5. Leave to settle for 3 – 5 minutes
6. Carry out a calibration of the unit as described in the product user manual
7. Ensure the oxygen reading is within ±0.75% of 20.9% O2
8. Change the gas cylinder to a 100% N2 cylinder (SA7L10308)
9. Set the flow rate to 0.2lpm
10. Leave to settle for 3 – 5 minutes
11. Verify that the O2 reading begins to fall and at about 19.5% the following activate: (Red LEDs, Sounder, Vibration motor (stops vibrating after 10 seconds), O2 reading shows a flashing outline and flashing symbol.
Note. 19.5% is a default O2 alarm level, this may vary if your device settings have been changed
12. Verify that at 18% O2, the LEDs and sounder begin to pulse faster
Note. 18% is a default O2 alarm level, this may vary if your device settings have been changed
13. Press the
button to mute the alarm
14. Note the O2 reading is correct to ±0.75% of 0% O2

Aspida Legislation
Standards such as OSHA, EH40 and TUV in Europe mandate that employees and members of the public are not exposed to potentially dangerous levels of CO2 as it is a highly toxic gas in relatively small quantities.
Guidelines also advise consideration be given to the use of oxygen monitors where inert gases such as nitrogen are used, as a leak can cause an asphyxiation risk.
The NHS SOPS (Standard Operating Procedures) also details the requirement for oxygen (O2) enrichment monitoring.
Analox are committed to helping you achieve your local and application specific legislation, please call us to discuss your requirements.
Technical Specification
Personal Protection
Enriched oxygen (O2) can cause a condition on the human body called hyperoxia, enriched CO2 is highly toxic, both are a threat to life and must be safeguarded against.
If an inert gas such as nitrogen (N2), argon (Ar), helium (He) or liquid nitrogen (LN2) leaks then this will deplete the levels of oxygen (O2) in the surrounding area, creating a dangerous atmosphere.
The Aspida can offer personal protection and alerts to all of these risks, offering you true peace of mind.
Ideal Solution
Offering audible and visual alarms, data logging and a man down alarm for lone workers, it is an ideal solution to protect staff from the dangers of a leak of carbon dioxide (CO2), oxygen (O2) or inert gas.
The Aspida is an affordable, easy to operate gas detection monitor and is perfect for ensuring safety in areas where the gas is piped, used or stored.
It operates using rechargeable battery technology allowing it to run for more than 12 hours continuously between charges.
